Back to the Future (1985)
Marty McFly: Wait a minute. Wait a minute, Doc. Ah... Are you telling me that you built a time machine... out of a DeLorean?
Dr. Emmett Brown: The way I see it, if you're gonna build a time machine into a car, why not do it with some *style?*

[1955 Doc is watching a video of 1985 Doc]
Dr. Emmett Brown: What on Earth is this thing I'm wearing?
Marty McFly: Ah, this, this is a radiation suit.
Dr. Emmett Brown: Radiation suit? Of course. 'Cause of all the fallout from the atomic wars.

[in the past, Marty observes his dad's incompetence]
Marty McFly: Jesus, George, it was a wonder I was even born.

Mr. Strickland: I noticed your band is on the roster for the dance auditions after school today. Why even bother, McFly? You don't have a chance. You're too much like your old man. No McFly ever amounted to anything in the history of Hill Valley!
Marty McFly: Yeah, well, history is gonna change.

[repeated line]
Marty McFly: If you put your mind to it, you can accomplish anything.

Biff Tannen: Mr. McFly! Mr. McFly, this just arrived. Oh, hi, Marty. I think it's your new book.
Lorraine Baines: Oh, honey! Your first novel.
George McFly: Like I've always told you, you put your mind to it, you can accomplish *anything*.
Biff Tannen: Oh, Marty. Marty, here's your keys. You're all waxed up, ready for tonight.
Marty McFly: Keys?

Marty McFly: "Too loud." I can't believe it. I'm never gonna get a chance to play in front of anybody.
Jennifer Parker: Marty, one rejection isn't the end of the world.
Marty McFly: Nah, I just don't think I'm cut out for music.
Jennifer Parker: But you're good, Marty. You're really good, and this audition tape of yours is great. You've gotta send it in to the record company. It's like Doc's always saying.
Marty McFly: Yeah, I know. I know. "If you put your mind to it, you can accomplish anything."
[Marty notices two girls walk by and looks at them]
Jennifer Parker: [turns Marty's head back to her] That's good advice, Marty.
Marty McFly: All right, okay, Jennifer. What if I send in the tape in and they don't like it? What if they say I'm no good? What if they say, "Get out of here kid. You've got no future"? I mean, I just don't think I can take that kind of rejection. Jesus, I'm starting to sound like my old man.
Jennifer Parker: Come on. He's not that bad. At least he's letting you borrow the car tomorrow night.
Marty McFly: [sees a tow truck pull up with a 4x4 Toyota on the flat bed] Check out that 4x4. That is hot. Someday, Jennifer. Someday. Wouldn't it be great to take that truck up to the lake? Throw a couple of sleeping bags in the back. Lie out underneath the stars.
Jennifer Parker: [smiling] Stop it.
Marty McFly: What?
Jennifer Parker: Does your mom know? About tomorrow night?
Marty McFly: No, get out of town. My mom thinks I'm going camping with the guys. Look, Jennifer, my mother would freak out if she knew I was going out with you, and I'd get the standard lecture about how she never did that kind of stuff when she was a kid. I mean, look, I think the woman was born a nun.
Jennifer Parker: She's just trying to keep you respectable.
Marty McFly: [puts his arm around her, flirting] Well, she's not doing a very good job.
Jennifer Parker: [both lean in to kiss] Terrible.

Marty McFly: [being chased by terrorists] Let's see if you bastards can do 90.

[concerning his audition tape]
Marty McFly: What if I send in the tape and they don't like it? I mean, what if they say I'm no good? What if they say, "Get outta here, kid. You got no future"? I mean, I just don't think I can take that kind of rejection. Jesus, I'm starting to sound like my old man!

Lou: You gonna order something, kid?
Marty McFly: Ah, yeah. Give me- Give me a Tab.
Lou: Tab? I can't give you a tab unless you order something.
Marty McFly: Right. Give me a Pepsi Free.
Lou: You want a Pepsi, pal, you're gonna pay for it.

Goldie Wilson: [rushes up to George] Say! Why do you let those boys push you around like that for?
George McFly: Well, they're bigger than me.
Goldie Wilson: Stand tall, boy. Have some respect for yourself. Don't you know, if you let people walk over you now, they'll be walking over you for the rest of your life. Look at me. You think I'm gonna spend the rest of my life in this slop house?
Lou: Watch it, Goldie.
Goldie Wilson: No, sir! I'm gonna make something of myself. I'm going to night school, and one day, I'm gonna be somebody!
Marty McFly: That's right! He's gonna be mayor.
Goldie Wilson: Yeah, I'm...
[smiles, one of his front teeth is gold]
Goldie Wilson: Mayor! Now *that's* a good idea! I could run for mayor.
Lou: A colored mayor. That'll be the day.
Goldie Wilson: You wait and see, Mr. Caruthers. I *will* be mayor! I'll be the most powerful man in Hill Valley, and I'm gonna clean up this town.
Lou: Good. You can start by sweeping the floor.
[hands Goldie a broom]
Goldie Wilson: [stands tall with a hand over his heart] Mayor Goldie Wilson. I like the sound of that.
[collects George's dishes]

[Dr. Emmett Brown is doubting Marty McFly's story about that he is from the future]
Dr. Emmett Brown: Then tell me, future boy, who's President of the United States in 1985?
Marty McFly: Ronald Reagan.
Dr. Emmett Brown: Ronald Reagan? The actor?
[chuckles in disbelief]
Dr. Emmett Brown: Then who's vice president? Jerry Lewis?
[rushing out and down a hill toward his laboratory]
Dr. Emmett Brown: I suppose Jane Wyman is the First Lady!
Marty McFly: [following Doc] Whoa. Wait, Doc!
Dr. Emmett Brown: And Jack Benny is secretary of the treasury.
Marty McFly: [outside the lab door] Doc, you gotta listen to me.
Dr. Emmett Brown: [opens the door to the lab] I've had enough practical jokes for one evening. Good night, future boy!
[closes the door leaving Marty outside]
Marty McFly: No, wait, Doc. Doc. The-the-the bruise on your head, I know how that happened. You told me the whole story. You were standing on your toilet and you were hanging a clock, and you fell and you hit your head on the sink. And that's when you came up with the idea for the flux capacitor,
Marty McFly: which is what makes time travel possible.
[Doc opens the door and looks at Marty with a stunned look on his face]

Marty McFly: Whoa. Wait a minute, Doc. Are you trying to tell me that my mother has got the hots for me?
Dr. Emmett Brown: Precisely.
Marty McFly: Whoa. This is heavy.
Dr. Emmett Brown: There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

[repeated line]
Marty McFly: This is heavy.

[referring to the DeLorean]
Marty McFly: [looks through a camcorder] This is heavy-duty, Doc. This is great. Uh, does it run, like, on regular unleaded gasoline?
Dr. Emmett Brown: Unfortunately, no. It requires something with a little more kick. Plutonium.
Marty McFly: Um, plutonium. Wait a minute. Are...
[lowers the camcorder]
Marty McFly: Are you telling me that this sucker is NUCLEAR?
Dr. Emmett Brown: Hey, hey, hey! Keep rolling. Keep rolling there.
[Marty raises the camcorder]
Dr. Emmett Brown: No, no, no, no, no, this sucker's electrical, but I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need.
Marty McFly: Doc, you don't just walk into a store and-and buy plutonium! Did you rip that off?
Dr. Emmett Brown: Of course. From a group of Libyan nationalists. They wanted me to build them a bomb, so I took their plutonium and, in turn, gave them a shoddy bomb casing full of used pinball machine parts. Come on! Let's get you a radiation suit. We must prepare to reload.

Dr. Emmett Brown: You're late! Do you have no concept of time?
Marty McFly: Hey, come on. I had to change. Do you think I'm going back in that-that zoot suit? The old man really came through. It worked!
Dr. Emmett Brown: What?
Marty McFly: He laid out Biff in one punch. I didn't know he had it in him. He's never stood up to Biff in his life!
Dr. Emmett Brown: [looks at the restored picture, realizing the implications of what Marty just said] Ever?

[last lines]
Marty McFly: Hey, Doc, we better back up. We don't have enough road to get up to 88.
Dr. Emmett Brown: Roads? Where we're going, we don't need roads.

George McFly: I know what you're gonna say, Son, and you're right.
[chuckles breathlessly]
George McFly: You're right. But, uh, Biff just happens to be my supervisor, and I'm afraid I'm just not very good at... confrontations.
Marty McFly: But the car, Dad. I mean, he wrecked it. He totaled it. I needed that car tomorrow night, Dad. I mean, do you have any idea how important this was to me? Do you have any clue?
George McFly: I know, and all I can say is I'm... I'm sorry.

Marty McFly: [watching a Honeymooners episode in 1955] Hey, hey, I've seen this one. I've seen this one. This is a classic. This is, uh, where Ralph dresses up as a man from space.
Milton Baines: What do you mean, you've seen this? It's brand new.
Marty McFly: Yeah, well, I saw it on a
Marty McFly: ... rerun.
Milton Baines: What's a rerun?
Marty McFly: You'll find out.

[Stella Baines is Marty's future grandmother]
Stella Baines: You know, Marty, you look so familiar to me. Do I know your mother?
Marty McFly: [turning to look at Lorraine, his mother in the future] Yeah, I think maybe you do...

[Marty sees the outside of the Hill Valley High School in 1955]
Marty McFly: Whoa. They really cleaned this place up. Looks brand-new.
[Marty and Doc walk toward the building]
Dr. Emmett Brown: Now, remember. According to my theory, you interfered with your parents' first meeting. If they don't meet, they won't fall in love, they won't get married and they won't have kids. That's why your older brother's disappearing from that photograph. Your sister will follow, and unless you repair the damage, you'll be next.
Marty McFly: Sounds pretty heavy.
Dr. Emmett Brown: Weight has nothing to do with it.

[on the phone while all the clocks chime at once]
Dr. Emmett Brown: Are those my clocks I hear?
Marty McFly: Yeah, it's 8:00.
Dr. Emmett Brown: Perfect! My experiment worked! They're all exactly 25 minutes slow!
Marty McFly: Wait a minute - wait a minute, Doc... are you telling me that it's 8:25?
Dr. Emmett Brown: Precisely.
Marty McFly: Damn! I'm late for school!
[hangs up, grabs his skateboard and rushes out]

Marty McFly: Do you know where Riverside Drive is?
Sam Baines: It's on the other end of town. A block past Maple. East end of town.
Marty McFly: A block past Maple? That's, uh, that's John F. Kennedy Drive.
Sam Baines: Who the hell is John F. Kennedy?

[on the phone]
Marty McFly: You know, Doc, you left your equipment on all week.
Dr. Emmett Brown: My equipment. That reminds me, Marty. You better not hook up to the amplifier. There's a slight possibility of overload.
Marty McFly: Yeah, I'll keep that in mind.

Marty McFly: [introducing his band] All right.
[microphone feedback]
Marty McFly: We're the, uh... We're the Pinheads.

Lorraine Baines: Kids, we're gonna have to eat this cake by ourselves. Your Uncle Joey didn't make parole again.
[drops the cake on the dining table. It reads "Welcome Home, Uncle Joey"]
Lorraine Baines: I think it would be nice if you all dropped him a line.
Marty McFly: Uncle "Jailbird" Joey?
Dave McFly: He's your brother, Mom.
Linda McFly: Yeah. I think it's a major embarrassment having an uncle in prison.
Lorraine Baines: We all make mistakes in life, children.

Marty McFly: [to Uncle Joey as a baby, playing in his playpen] So you're my Uncle Joey. Better get used to these bars, kid.

George McFly: You really think I ought to swear?
Marty McFly: Yes, definitely. Goddamn it, George, swear.

Dr. Emmett Brown: Oh, my God. They found me. I don't know how, but they found me. Run for it, Marty!
Marty McFly: Who? Who?
Dr. Emmett Brown: Who do you think? THE LIBYANS!
Marty McFly: HOLY SHIT!

Dr. Emmett Brown: [the DeLorean has just made the first time-jump] Ah! What did I tell you? 88 miles per hour! The temporal displacement occurred exactly 1:20 a.m. and zero seconds!
Marty McFly: Ah, Jesus Christ! Jesus Christ, Doc, you disintegrated Einstein!
Dr. Emmett Brown: Calm down, Marty. I didn't disintegrate anything. The molecular structure of both Einstein and the car are completely intact.
Marty McFly: Then where the hell are they?
Dr. Emmett Brown: The appropriate question is, "*When* the hell are they?" You see, Einstein has just become the world's first time traveler! I sent him into the future. One minute into the future to be exact. And at precisely 1:21 a.m. and zero seconds, we shall catch up with him and the time machine.

Younger Dr. Emmett Brown: [running out of the room] 1.21 gigawatts! 1.21 gigawatts. Great Scott!
Marty McFly: [following] What-what the hell is a gigawatt?

Marty McFly: Look, Marvin, you gotta play. See, that's where they kiss for the first time on the dance floor. And if there's no music, they can't dance. If they can't dance, they can't kiss. If they can't kiss they can't fall in love, and I'm history.

[addressing the shocked expressions at the dance after playing a wild heavy metal guitar solo]
Marty McFly: I guess you guys aren't ready for that yet. But your kids are gonna love it.

[Marty and Doc observe George's incompetence in 1955]
Dr. Emmett Brown: Which one's your pop?
Marty McFly: [points him out] That's him.
[they see him getting kicked around by other school bullies]
George McFly: [has a "kick me" sign on his back] Okay. Okay, you guys. Ah-ha-ha-ha. Very funny. You guys are being real mature.
Dr. Emmett Brown: Maybe you were adopted.

Dr. Emmett Brown: Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.
Marty McFly: [startled] What did you say?
Dr. Emmett Brown: A bolt of lighting. Unfortunately, you never know when or where it's ever gonna strike.
Marty McFly: We do now.
[hands Doc the "Save the Clock Tower" flyer]

Marty McFly: That's Strickland. Jesus, didn't that guy ever have hair?

Marty McFly: Calvin? Wh... Why do you keep calling me Calvin?
Lorraine Baines: Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear.

Marty McFly: Hey, Dad! George! Hey, you on the bike!

Marty McFly: [heads for a door then stops] Oh. One other thing. If you guys ever have kids, and one of them, when he's eight years old, accidentally sets fire to the living room rug... go easy on him.

[seeing a poster for the Enchantment Under the Sea dance]
Dr. Emmett Brown: Look! There's a rhythmic ceremonial ritual coming up.
Marty McFly: Of course! The Enchantment Under the Sea dance! They're supposed to go to this. That's where they kiss for the first time.
Dr. Emmett Brown: All right, kid. You stick to your father like glue and make sure he takes her to that dance.

Marty McFly: [acting cool] Do you mind if we... park... for a while?
Lorraine Baines: That's a great idea. I'd love to park.
Marty McFly: Huh?
Lorraine Baines: Marty, I'm almost 18 years old. It's not like I've never parked before.
Marty McFly: What?
Lorraine Baines: Marty, you seem so nervous. Is something wrong?
Marty McFly: [trying to maintain composure] No. No.
[Lorraine takes a sip from a liquor bottle]
Marty McFly: [grabbing the bottle from Lorraine] Lorraine! Lorraine, what are you doing?
Lorraine Baines: [starting to laugh] I swiped it from the old lady's liquor cabinet.
Marty McFly: Yeah, well, you shouldn't drink.
Lorraine Baines: Why not?
Marty McFly: Because you... You might regret it later in life.
Lorraine Baines: Marty, don't be such a square. Everybody who's anybody drinks.
[Marty takes a sip from Lorraine's bottle then spit-takes as he notices Lorraine lighting a cigarette]
Marty McFly: [nauseatingly] Jeez! You smoke, too?
Lorraine Baines: Marty, you're beginning to sound just like my mother.

[Marty wakes up in Lorraine's bed]
Marty McFly: Mom. That you?
Lorraine Baines: There, there, now. Just relax.
[pats a damp cloth on Marty's forehead]
Lorraine Baines: You've been asleep for almost nine hours now.
Marty McFly: I had a horrible nightmare. I dreamed that I went... back in time. It was terrible.
Lorraine Baines: Well, you're safe and sound now, back in good old 1955.
Marty McFly: [opens his eyes wide] 1955?

Dr. Emmett Brown: You've got to get your father and mother to interact in some sort of social...
Marty McFly: Wh-what? You mean like a date?
Dr. Emmett Brown: Right!
Marty McFly: What kind of date? I don't know. What do kids do in the '50s?
Dr. Emmett Brown: Well, they're your parents. You must know them. What are their common interests? What do they like to do together?
Marty McFly: Nothing.

Marty McFly: Okay. Time circuit's on. Flux capacitor, fluxing. Engine running. All right.
[the engine stops suddenly]

Lorraine Baines: Marty, will we ever see you again?
Marty McFly: I guarantee it.

Marty McFly: [sees that he has destroyed the huge speaker] Whoa! Rock 'n' Roll.

[Marty places headphones over his father's ears and wakes him up by playing Van Halen music at full blast. George wakes up screaming - Marty pauses the music. George looks up to see Marty, who is unrecognizable because he is wearing a radiation suit]
George McFly: Who are you?
Marty McFly: [after giving him another earful of loud rock music] Silence, Earthling. My name is Darth Vader. I am an extraterrestrial from the planet Vulcan!
[makes Live Long and Prosper sign with his hand]

Lorraine Baines: It's our first television set. Dad just picked it up today. Do you have a television?
Marty McFly: Well, yeah. You know we have... two of them.
Milton Baines: Wow! You must be rich.
Stella Baines: Oh, honey, he's teasing you. Nobody has two television sets.

Dr. Emmett Brown: Let me show you my plan for sending you home. Please excuse the crudity of this model. I didn't have time to build it to scale or paint it.
[reveals intricate tabletop model of the town square]
Marty McFly: [impressed] It's good.

Mr. Strickland: Am I to understand you're still hanging around with Dr. Emmett Brown, McFly?
[clicks with his mouth, gives Jennifer a tardy slip]
Mr. Strickland: Tardy slip for you, Miss Parker.
[gives Marty one, too]
Mr. Strickland: And one for you, McFly; I believe that makes four in a row. Now let me give you a nickel's worth of free advice, young man. This so-called Dr. Brown is dangerous. He's a real nutcase. You hang around with him, you're gonna end up in big trouble.
Marty McFly: [sarcastically] Ooh, yes, sir.
Mr. Strickland: [pushes Marty a little bit] You got a real attitude problem, McFly; you're a slacker. You remind me of your father when he went here; he was a slacker, too.

Marty McFly: [whilst with his girlfriend] What happens to us in the future? Do we become assholes or something?

Dr. Emmett Brown: [Marty is showing Doc Brown the flux capacitor in the DeLorean time vehicle] It works! It works!
[grabs Marty]
Dr. Emmett Brown: I finally invent something that works!
Marty McFly: [quietly] You bet your ass it works.

Marty McFly: Where are my pants?
Lorraine Baines: Over there, on my hope chest.

Marty McFly: Since when can weathermen predict the weather, let alone the future?

Lorraine Baines: Marty? Why are you so nervous?
Marty McFly: Lorraine. Have you ever been in a situation where you knew you had to act a certain way, but when you got there, you didn't know if you could go through with it?
Lorraine Baines: You mean like how you're supposed to act on a first date?
Marty McFly: [stammering] Sort of.
Lorraine Baines: I think I know exactly what you mean. You know what I do in those situations?
Marty McFly: You do? What?
Lorraine Baines: I don't worry.
[kisses him hard]
Lorraine Baines: [Lorraine stops and pulls back, Marty is freaking out]
Lorraine Baines: This is all wrong. I don't know what it is. But when I kiss you, it's like I'm kissing... my brother. I guess that doesn't make any sense, does it?
Marty McFly: Believe me, it makes perfect sense.

Marty McFly: [Marty has just woken up to a new and improved 1985, and sees his brother and sister well-dressed and sitting at the dinner table, eating breakfast]
Marty McFly: Hey. What the hell is this?
Linda McFly: Breakfast.

Dr. Emmett Brown: [Deleted Scene, Doc Brown uses a sound fork and hits the time machine with the sound fork and frantically steps back] I knew, I knew it, I knew it.
Marty McFly: Doc, do you have a 75-ohm matching transformer?
Dr. Emmett Brown: What?
Marty McFly: [Realizing where in time he is] Not invented yet. That's right.
Dr. Emmett Brown: [Walks over to his future self's suit case] So, these are my personal belongings, huh?
Marty McFly: Yeah.
Dr. Emmett Brown: [Opens up the suit case and picks up a hair dryer] What's this thing?
Marty McFly: It's a hair dryer.
Dr. Emmett Brown: A hair dryer? Don't they have towels in the future?
Dr. Emmett Brown: [Picks up a pair of underwear] Oh, look at these underpants. They're all made of cotton. I though for sure we'd all be wearing disposable paper garments by 1985.
Dr. Emmett Brown: [Picks up a Playboy Magazine] What's... this?
[Looks at the magazine]
Dr. Emmett Brown: [exclaims] Suddenly, the future's looking a *whole* lot better.

Dr. Emmett Brown: [Doc has just finished the final preparations for Marty's return to 1985] Well, I guess that's everything.
Marty McFly: [pause] Thanks.
Dr. Emmett Brown: Thank *you*!
[Marty emotionally embraces Doc, which surprises him]
Dr. Emmett Brown: See you in about 30 years.
Marty McFly: I hope so.

Marty McFly: [Doc has just been shot. Marty runs over to him] Doc! Doc!
Marty McFly: [Marty turns Doc's body over to reveal it is apparently bullet-ridden and lifeless. Marty begins to cry] No! No!
Marty McFly: [Doc suddenly blinks and sits up] You're alive.
Marty McFly: [Doc unzips his radiation suit to reveal a bulletproof vest underneath] Bulletproof vest? How did you know? I never got a chance to tell you.
Marty McFly: [Doc smiles and removes a weathered piece of paper from his pocket. Marty unfolds the paper to reveal it is the warning letter he had written in 1955, taped back together] What about all that talk about screwing up future events? The space-time continuum?
Dr. Emmett Brown: Well, I figured, what the hell?

1955 radio weatherman: [It's Marty's last night in 1955. Doc is setting up the cable that will channel the lightning bolt into the time machine] ... Hill Valley area weather this Saturday night. Mostly clear, with some scattered clouds. Lows tonight in the upper 40s.
Dr. Emmett Brown: Are you sure about this storm?
Marty McFly: Since when can weathermen predict the weather, let alone the future?
Dr. Emmett Brown: You know, Marty, I'm gonna be very sad to see you go. You've really made a difference in my life. You've given me something to shoot for. Just knowing that I'm going to be around to see 1985. That I'm gonna succeed in this!
[gestures at time machine]
Dr. Emmett Brown: That I'm gonna have a chance to travel through time!
[Marty looks solemn, knowing that Doc is destined to be murdered before he gets to use the time machine himself]
Dr. Emmett Brown: It's gonna be really hard waiting 30 years before I can talk to you about everything that's happened in the past few days. I'm really gonna miss you, Marty.
Marty McFly: I'm really gonna miss *you*.
Marty McFly: Doc, about the future...
Dr. Emmett Brown: No! Marty! We've already agreed that having information about the future can be extremely dangerous. Even if your intentions are good, it can backfire drastically!
[Marty nods reluctantly]
Dr. Emmett Brown: Whatever you've got to tell me, I'll find out through the natural course of time.

Marty McFly: [Reading a letter he has just written] Dear Dr. Brown. On the night that I go back in time, you will be shot by terrorists. Please take whatever precautions are necessary to prevent this terrible disaster. Your friend, Marty.
[Writes the words "Do not open until 1985" on the envelope]

George McFly: I've never picked a fight in my entire life.
Marty McFly: Look, you're not gonna be picking a fight, Dad... Dad-Dad-Daddy-O.

Marty McFly: Let's go over the plan again, so eight-thirty where are you going to be?
George McFly: I'm gonna be at the dance.
Marty McFly: And where am I gonna be?
George McFly: You're going to be in the car with her...
Marty McFly: Right, so right around nine o'clock she's going to get very angry with me.
George McFly: Why would she get angry with you?
Marty McFly: [reluctantly] Because, George, nice girls get angry when guys take advantage of them.
George McFly: [Realizing] Ho! Hooo! You-you mean you're going to go touch her on her -
[gestures at a bra in his hand]
Marty McFly: No, no, no listen, George it's just an act! Okay? So around nine o'clock you're walking through the parking lot, you see us... struggling in the car. You walk up, you open the door and you say
Marty McFly: ... your line, George!
George McFly: Oh! "Hey you! Get your damn hands off her!"

[in 1955, catching George spying on a woman undressing in her bedroom]
Marty McFly: He's a Peeping Tom!

Marty McFly: This is heavy.
Dr. Emmett Brown: Weight has nothing to do with it.

Marty McFly: He laid out Biff in one punch. I didn't know he had it in him. He's never stood up to Biff in his life!
Dr. Emmett Brown: [looks at the picture, realizing the implications of Marty's statement] Ever?

Dr. Emmett Brown: [Doc Brown is trying to read Marty's mind with a geodesic helmet and a suction cup] Erm, you want me to make a donation to the Coastguard Youth Auxilliary?
Marty McFly: Doc,
[pulls off suction cup]
Marty McFly: I'm from the future. I came here in a Time Machine that you invented. Now I need your help to get back to the year 1985.
Dr. Emmett Brown: My God. Do you know what this means?
[Significant pause]
Dr. Emmett Brown: It means that this damn thing doesn't work at all!
[Rips the helmet off]

Marty McFly: My name is Lord Vader. I am an Extraterrestrial from the planet Vulcan.

George McFly: [on the day after the evening Marty disguises himself as an alien and makes a threatening visit to George] Marty! Marty! Marty!
Marty McFly: Hey, George, buddy, you weren't at school. What have you been doing all day?
George McFly: I overslept. Look, I need your help. I have to ask Lorraine out but I don't know how to do it.
Marty McFly: Alright, okay, listen, keep your pants on. She's over in the cafe.
[George heads for the cafe, Marty races after him]
Marty McFly: What made you change your mind, George?
George McFly: [loud enough for a couple walking by to hear] Last night, Darth Vader came down from Planet Vulcan and told me that if I didn't take Lorraine, that he'd melt my brain!
Marty McFly: Yeah, well, uh, let's keep this brain-melting stuff to ourselves, okay?
George McFly: Oh, yeah! Yeah!

Back to the Future Part III (1990)
Marty McFly: Listen, you got a back door to this place?
Bartender: Yeah, it's in the back.

Doc: You're just not thinking fourth dimensionally!
Marty McFly: Right, right. I have a real problem with that.

Jennifer Parker: Dr. Brown, I brought this note back from the future and - now it's erased.
Doc: Of course it's erased!
Jennifer Parker: But what does that mean?
Doc: It means your future hasn't been written yet. No one's has. Your future is whatever you make it. So make it a good one, both of you.
Marty McFly: [Marty wraps his arm around Jennifer] We will, Doc.

Doc: Marty, I gave you explicit instructions not to come here but to go directly back to 1985.
Marty McFly: I know, Doc. But I had to come.
Doc: But it's good to see ya, Marty.

[at the town festival]
Buford "Mad Dog" Tannen: Then let's finish it, right now!
Buford's Gang Member #1: Uh, not now, Buford. Uh, Marshal's got our guns.
Buford "Mad Dog" Tannen: Like I said, we'll finish this tomorrow.
Buford's Gang Member #2: Tomorrow, we're robbin' the Pine City Stage.
Buford "Mad Dog" Tannen: What about Monday? Are we doin' anything Monday?
Buford's Gang Member #1: Uh, no, Monday'd be fine. You can kill him on Monday.
Buford "Mad Dog" Tannen: I'll be back this way on Monday! We'll settle this then... right there... out in the street... in front of the Palace Saloon!
Marty McFly: Yeah, right. When? High noon?
Buford "Mad Dog" Tannen: Noon? I do my killin' before breakfast! Seven o'clock!
Marty McFly: Eight o'clock. I do my killin' after breakfast!

[last lines]
Marty McFly: Hey, Doc! Where you goin' now? Back to the future?
Doc: Nope. Already been there.

Young Doc: No wonder this circuit failed. It says "Made in Japan".
Marty McFly: What do you mean, Doc? All the best stuff is made in Japan.
Young Doc: Unbelievable.

Marty McFly: You're Mad Dog Tannen!
Buford "Mad Dog" Tannen: Mad Dog? I hate that name. I hate it. You hear? Nobody calls me "Mad Dog", especially not some duded-up, egg-suckin' gutter trash.

Bartender: [the bartender and his assistant, Joey mix up a special "wake-up juice" using hot peppers, Tabasco sauce and chili powder] In about ten minutes, he's gonna be as sober as a priest on Sunday.
Marty McFly: [sees clock outside - they have 10 minutes to get to the train] Ten minutes? Why do we have to cut these things so damn close?

[Marty and Doc finally say each other's phrases the opposite way]
Marty McFly: Great Scott!
Doc: I know, this is heavy.

[Marty is left-behind back in 1955, with the young Doc of then as his only hope to getting back to the future]
Marty McFly: I'm sorry, Doc. It's all my fault you're stuck back there. I never should have let Biff get to me!
Young Doc: Well, there are plenty worse places to be than the Old West. I could've ended up in the Dark Ages. They probably would have burned me at the stake as a heretic or something.

Buford "Mad Dog" Tannen: What's your name, dude?
Marty McFly: Uh, Mar- Eastwood. Clint Eastwood.
Buford "Mad Dog" Tannen: What kind of stupid name is that?

[Marty teases Doc about his and Clara's reaction to each other]
Doc: Well, she did have quite a shock. After all, Miss Clayton almost ended up at the bottom of Clayton Ravine...
Doc: Clayton Ravine...
Marty McFly: Holy shit, Doc! Clayton Ravine was named after a teacher. They say she fell in there a hundred years ago.
Doc: A hundred years ago? That's this year!
Marty McFly: Every kid in school knows that story 'cause we all have teachers we'd like to see fall into that ravine.

Buford "Mad Dog" Tannen: You owe me money, blacksmith.
Doc: How do ya figure?
Buford "Mad Dog" Tannen: My horse threw a shoe. And seein' as you was the one that done the shoein', I say that makes you responsible.
Doc: Well, since you never paid me for the job, I say that makes us even!
Buford "Mad Dog" Tannen: Wrong! See I was *on* my horse when it threw the shoe and I got throwed *off*! And *that* caused me to bust a perfectly good bottle of fine Kentucky red-eye. So, the way I figure it, blacksmith, you owe me five dollars for the whiskey and $75 for the horse.
Marty McFly: [hoarsely] That's the $80.
Doc: Look! If your horse threw a shoe, bring him back and I'll reshoe him!
Buford "Mad Dog" Tannen: I done shot that horse!
Doc: Well, that's your problem, Tannen!
Buford "Mad Dog" Tannen: Wrong! That's yours. So, from now on, you better be lookin' behind you when you walk. 'Cause one day you're gonna get a bullet in your back.
[Buford and his gang gallop away on their horses]

[Holding baby William]
Marty McFly: So you're my great-grandfather. The first McFly born in America. And you peed on me.

Marty McFly: How many did he have?
Bartender: Just the one.
Marty McFly: Just the one? Come on, Doc!
Bartender: There's a fella that can't hold his liquor.

Doc: Marty, you're going to have to do something about those clothes. You walk around town dressed like that, you're liable to get shot.
Marty McFly: Or hanged.
Doc: What idiot dressed you in that outfit?
Marty McFly: You did.

Buford "Mad Dog" Tannen: [arriving at the Palace Saloon] Are you in there, Eastwood? It's eight o'clock, and I'm callin' you out!
Marty McFly: [looks at the town clock, then steps towards Buford cautiously at a window] It's not 8:00 yet!
Buford "Mad Dog" Tannen: It is by my watch! Let's settle this once and for all, runt! Or ain't you got the gumption?

Marty McFly: I had this horrible nightmare. Dreamed I w-... dreamed I was in a western. And I was being chased by all these Indians... and a bear.
Maggie McFly: Well... you're safe and sound here, now, at the McFly farm.
Marty McFly: McFly farm? Why, you're my, you're my, my... who are you?

Marty McFly: [upon arriving in 1885; sees Indians on horseback, galloping towards him] Indians!

[in a Drive-In, in 1955. The theater screen shows a still picture of a group of Native Americans riding horse in a desert]
Young Doc: All you have to do is drive the time vehicle directly toward that screen accelerating to 88 miles an hour.
Marty McFly: Wait a minute, Doc. If I drive straight towards the screen, I'm gonna crash into those Indians.
Young Doc: Marty, you're not thinking fourth dimensionally. You'll instantly be transported back into 1885, and those Indians won't even be there.
Marty McFly: Right.
Young Doc: Well, good luck for both our sakes. See you in the future.
Marty McFly: You mean the past?
Young Doc: Exactly!
[after a few minutes, when he uses the DeLorean and lands in 1885... an actual group of Native Americans is literally running towards his location]
Young Doc: [shouting frantically]
Marty McFly: Uhhhhh... Indians!

Marty McFly: [gears up before going to 1885] Hi-ho, Silver!

Colt Gun Salesman: [the gun salesman is amazed at Marty's gunmanship at a shooting gallery] Uh, just tell me one thing. Where'd you learn to shoot like that?
Marty McFly: 7-Eleven.

Townsman #1: Good morning, Mr. Eastwood.
Marty McFly: Morning.
Townsman #2: [hands Marty a cigar] Have a cigar, Mr. Eastwood. Anything I can do you for you today Mr. Eastwood?
Marty McFly: Uh, no. That's fine. I don't...
Townsman #3: Good luck tomorrow, Mr. Eastwood. We'll be prayin' for ya.
Marty McFly: Thanks.
Undertaker: [holding a funeral suit] Good morning, Mr. Eastwood. Interest you in a new suit for tomorrow?
Marty McFly: Uh, I'm-I'm fine. Thanks.

Undertaker: Excuse me, Mr. Eastwood. I just need your measurement.
[measures Marty]
Marty McFly: Aw, look, pal. I don't wanna buy a suit.
Undertaker: [chuckles] No. This is for your coffin.
Marty McFly: [realizing what is going on] My coffin?
Undertaker: Well, the odds are running 2 to 1 against you. Might as well be prepared.

Doc: [into the walkie-talkie from inside the cab of the train] Each detonation will be accompanied by a sudden burst of acceleration. Hopefully, we'll hit 88 mph, before the needle gets much past 2,000.
Marty McFly: [into the walkie-talkie] Why, what-what happens after it hits 2,000?
Doc: [into the walkie-talkie] The whole boiler explodes.
Marty McFly: Perfect!

Young Doc: Well, good luck for both of our sakes. See you in the future.
Marty McFly: You mean the past.
Young Doc: Exactly!

Colt gun salesman: I'd like for you to have this new Colt Peacemaker and gun belt. Free of charge.
Marty McFly: Free?
Colt gun salesman: I want everybody to know that the gun that shot Buford Tannen was a Colt Peacemaker.
Marty McFly: Hey-hey, no problem. Thanks a lot!
Colt gun salesman: Of course, uh, you understand, that if you lose, I'm takin' it back.
Marty McFly: Thanks again.

[Marty McFly just found a tombstone with Emmett Brown's name]
Marty McFly: Doc! Doc! Come here quick!
Young Doc: What's wrong, Marty? You look like you've seen a ghost.
Marty McFly: You're not far off, Doc.

[1885 - Marty walks into a saloon, dressed in the outfit that Doc Brown gave him in 1955]
Saloon Old-Timer #1: Take a look and see what just breezed in the door.
Saloon Old-Timer #2: Why, I didn't know the circus was in town.
Saloon Old Timer #3: Musta got that shirt off'n a dead Chinee.
Bartender: What'll it be, stranger?
Marty McFly: Uh, I'll have an... ice water.
[the old-timers laugh]
Saloon Old Timer #3: Ice water?
Bartender: Water? You want water, you better go dunk ya head in the horse trough out there.
[pulls out a shot glass and pours into it]
Bartender: In here, we pour whiskey.

Doc: [reading a letter his future self wrote] I never knew I could write anything so touching.
Marty McFly: I know, Doc, it's beautiful.

Marty McFly: [Doc and Marty use explosives to get in the old Delgado mine, which is near a graveyard] I think you woke up the dead with that blast!

Marty McFly: [holding up a plate that says "Frisbee"] Hey, Frisbee, far-out.
Seamus McFly: What was the meanin' of that?
Maggie McFly: It was right in front of him.

Marty McFly: [reading the gravestone of Doc's future self] "Erected in eternal memory by his beloved Clara."
Marty McFly: [he turns to face Doc, inadvertently standing on the grave] Who the hell is Clara?
Young Doc: [shouts] Marty, please, don't stand there!

Marty McFly: Hey, lighten up, jerk!

[Marty and Doc are asking how fast the train could go]
Marty McFly: Do you think it's possible to get it up to... 90?
Engineer: Ha! 90? Tarnation, son, who'd ever need to be in such a hurry?
Doc: Well, it's just a little bet he and I have, that's all. Theoretically speaking, could it be done?
Engineer: Well, I suppose if you had a straight stretch of track with a level grade, and you weren't haulin' no cars behind you, and if you can get the fire hot enough, and I'm talkin' about hotter than the blazes of hell and damnation itself... then yes, it might be possible to get her up that fast.

[Clara is crawling on the train car filled with wooden fire logs]
Marty McFly: [into walkie talkie] You better hold on to somethin' Doc, the yellow log's about to blow!
[a large explosion occurs, sending a wave of sparks at Clara, knocking her over]
Clara Clayton: [sits up] Golly!

[Clara has pulled the train's whistle, causing Doc to look back towards the cab]
Clara Clayton: [Waves] Emmett!
Doc: Clara!
Clara Clayton: I love you!
Marty McFly: [Into walkie talkie] Doc! Doc, what's happening?
Doc: [Into walkie talkie] It's Clara, she's on the train!
Marty McFly: [to himself] Clara? Perfect.
Doc: [Into walkie talkie] She's in the cab; I'm gonna go back for her!
Marty McFly: [Into walkie talkie] The windmill! Doc! The windwill, we're goin' past fifty, you'll never make it!
Doc: [Into walkie talkie] Then we'll have to take her back with us, but keep calling out the speed!

Doc: Clara! Climb out here to me!
Clara Clayton: I don't know if i can!
Doc: You can do it; just don't look down!
[Clara looks down at the churning wheels and starts leaning out]
Doc: That's it!
[Clara climbs over the cab and steps her high-heeled boots onto the train's thin, precarious ledge]
Marty McFly: [Into walkie talkie] 60 miles an hour, Doc!

[Doc has altered history by saving Clara from falling into what would have been Clayton Ravine]
Marty McFly: Look, Doc, what's the worst that can happen, huh? So they don't name the ravine after her. Let's just get the DeLorean ready and get the hell out of here.
Doc: I wish I'd never invented that infernal time machine. It's caused nothing but disaster.

Jennifer Parker: [Marty floors his truck in reverse and turns the other way while Needles speeds off down the street] Did you do that on purpose?
Marty McFly: Yeah. You think I was stupid enough to race that asshole?
[they watch as a Rolls-Royce pulls out of a drive-way, not yielding the right of way, and Needles screeches on his breaks and zips around it. Marty is shocked to realize something valuable about his fate]
Marty McFly: [to himself] I would have hit that Rolls-Royce.

[Marty is still wearing his 1985 shoes]
Young Doc: Marty, you have to wear the boots. You can't wear those futuristic things back in 1885. You shouldn't even be wearing them here in 1955.
Marty McFly: Alright, Doc. Look, as soon I get there, I'll put them on. I promise.

[first lines]
Marty McFly: Doc! Doc! Doc!
Young Doc: [not paying attention] What?
Marty McFly: Doc!
Young Doc: What?
Marty McFly: Doc!
Young Doc: [finally seeing him] Aaaah!
Marty McFly: Okay, relax, Doc, it's me! It's me, It's Marty!
Young Doc: No, it can't be! I just sent you back to the future!
Marty McFly: Oh, I know you did send me back to the future. But I'm back, I'm back *from* the future.
Young Doc: Great Ssscott!

[repeated line]
Marty McFly: This is heavy.

Marty McFly: You're the doc, Doc.

Marty McFly: [running into the Saloon] Doc. What are you doin'?
Doc: I've lost her, Marty. There's nothing left for me here.
Marty McFly: Yeah, that's why you gotta come back with me.
Doc: Where?
Marty McFly: Back to the future.
Doc: [Nods his head] Right. Let's get going.
[puts down his glass of whiskey]
Marty McFly: [muffled] Great.
Doc: Gentlemen, excuse me. But, my friend and I have to catch a train.
Saloon Old-Timer #1: Cheers to ya, blacksmith.
Saloon Old Timer #3: And to the future.
Saloon Old-Timer #2: Amen.
Doc: [picks up his glass of whiskey] Amen.
Bartender: Emmett, no!
[Doc throws back the whiskey and turns and passes out, tipping over a table in the process]

Marty McFly: Bartender says that's the strongest stuff they got.
[Doc begins to pour alcohol into the DeLorean's gas cap]
Doc: Try it, Marty.
[Marty is trying to start the engine in the DeLorean. The engine begins to sorely start as he keeps turning the keys to work the engine]
Doc: Give it more gas...
[the DeLorean sounds as if its about to start until the fuel-injection manifold blows apart from the car with a lot smog as the car dies; Doc picks it up]
Doc: Damn! It blew the fuel injection manifold. Strong stuff alright, it'll take me a month to rebuild it.
Marty McFly: A month? Doc, you're gonna get shot on Monday!
Doc: I know, I know...! Wait, I've got it! we can simply roll it down a steep hill... no, no, we'd never find a smooth enough surface. Unless... of course, ice! We'll wait until winter, when the lake freezes over we'll...
Marty McFly: Winter? Doc! Monday, it's three days away!
Doc: Okay, okay, let's think this through logically... we know that it won't run under its own power and we know we can't pull it, but if we could find a way to push it up to 88 miles per hour...
[a whistle blows in the distance and Doc looks out the window at the arriving train]
Doc: That's it!

[in a library in 1955]
Doc: [reading a short biography about Buford Tannen] "Buford Tannen was a notorious gunman, whose short temper and a tendency to drool, earned him the nickname 'Mad Dog.' He was quick on the trigger and bragged that he'd killed 12 men, not including Indians or Chinamen."
Marty McFly: Does it mention me? Am I one of the 12?
Doc: [Puts up his finger] Just a minute. "However, this can not be substantiated since precise records were not kept after Tannen shot a newspaper editor who printed an unfavorable story about him in 1884." That's why we can't find anything.
Marty McFly: [Brings over a set of books] Look. "William McFly and family." Your relatives?
Marty McFly: My great-grandfather's name was William.
[Points to William]
Doc: That's him, good looking guy.
Marty McFly: Maybe it was just a mistake, Doc. Maybe that grave wasn't yours. There could've been another Emmett Brown back in 1885.
Doc: No.
Marty McFly: Did you have relatives here back then?
Doc: The Browns didn't come to Hill Valley until 1908. Then, they were the Von Brauns. My father changed our name during the first World War.
Marty McFly: [discovers a picture of Doc] Doc, look.
Doc: Great Scott. It's me! Then, it *is* true. All of it. It is me who goes back there and gets shot.
Marty McFly: It's not gonna happen, Doc. After you fix the time circuits and put new tires on the DeLorean, I'm gonna go back to 1885 and I'm bringing you home.

Doc: Marty, why are you wearing that gun? You're not considering going up against Tannen tomorrow?
Marty McFly: Doc, tomorrow morning, I'm going back to the future with you. But if Buford Tannen comes looking for trouble, I'm gonna be ready for him. You heard what that son of a bitch called me last night.
Doc: Marty, you can't go losing your judgment every time someone calls you a name. That's exactly what causes you to get into that accident in the future.
Marty McFly: What? What about my future?
Doc: I can't tell you. It might make things worse.
Marty McFly: Wait a minute, Doc. What is wrong with my future?
Doc: Marty, we all have to make decisions that affect the course of our lives. You've gotta do what you've gotta do. And I've gotta do what I've gotta do.

Doc: [consulting a map of the train line] This spur runs off the main line three miles down to Clayton Ravine. There's a long stretch of track that will still exist in 1985. This is where we'll push the DeLorean with the locomotive. Funny, this map calls Clayton Ravine "Shonash Ravine"... that must be an old Indian name for it. It's perfect, a nice long run that goes clear across the bridge over the ravine, you know, over near that Hilldale housing development.
Marty McFly: Right, Doc, but according to this map, there is no bridge.
[cut to Marty and Doc standing at the end of the track overlooking the ravine]
Marty McFly: Well, Doc, we can scratch that idea. I mean, we can't wait around a year and a half for this thing to get finished.
Doc: Marty, it's perfect, you're just not thinking fourth-dimensionally!
Marty McFly: [sotto voice] Right, right. I have a real problem with that.
Doc: Don't you see? The bridge *will* exist in 1985. It's safe and still in use. Therefore, as long as we get the DeLorean up to 88 miles per hour before we hit the edge of the ravine, we'll instantaneously arrive at a point in time where the bridge is completed. We'll have track under us and coast safely across the ravine!
Marty McFly: What about the locomotive?
Doc: It'll be a spectacular wreck. Too bad no one will be around to see it.

[Marty has accepted Tannen's challenge to duel]
Seamus McFly: You had him, Mr. Eastwood! You could have just walked away and nobody would of thought the less of you for it. All it would have been was words... hot air from a buffoon. Instead, you let him rile you, rile you into playin' his game, his way, by his rules.
Marty McFly: Seamus, relax, I know what I'm doin'.
Maggie McFly: He reminds me of poor Martin.
Seamus McFly: Aye.
Marty McFly: Who?
Seamus McFly: Me brother.
Marty McFly: Wait a minute, you have a brother named Martin McFly?
Seamus McFly: *Had* a brother. Martin used to let men provoke him into fightin'. He was concerned people would think him a coward if he refused. That's how he got a Bowie knife shoved through his belly at a saloon in Virginia City. Never considered the future, poor Martin, God rest his soul.
Maggie McFly: Sure'n I hope you're considerin' the future, Mr. Eastwood.
[she walks away]
Marty McFly: [to himself] I think about it all the time.

[Doc and Marty load the DeLorean onto the train tracks]
Doc: Marty, I've made a decision. I'm not going with you tomorrow. I'm staying here.
Marty McFly: What are you talkin' about, Doc?
Doc: There's no point in denying it. I'm in love with Clara.
Marty McFly: Oh, man. Doc, we don't belong here! Neither one of us! You know, it could still be you that gets shot tomorrow!
[shows Doc the photo of the blank tombstone]
Marty McFly: This tombstone could still be in your future!
Doc: Marty, the future isn't written. It can be changed. You know that. Anyone can make their future whatever they want it to be. I can't let this one little photograph determine my entire destiny. I have to live my life according to what I believe is right in my heart.
Marty McFly: Doc, you're a scientist.
[points to Doc's heart]
Marty McFly: So you tell me: What's the right thing to do?
Marty McFly: [points to his own forehead] Up here?
Doc: [sighs and looks again at the photograph] You're right, Marty.
[they release the DeLorean onto the tracks]
Marty McFly: Wow, that worked great.
Doc: I've at least gotta tell her goodbye.
Marty McFly: C'mon, Doc. I mean, think about it. What are you gonna say to her? "I gotta go back to the future"? I mean, she's not gonna understand that, Doc. Hell, I'm in it with you and even I don't understand it.
Marty McFly: Doc. Listen, maybe we could - I don't know. Maybe we could just take Clara with us.
Doc: To the future?
[shakes his head]
Doc: As you reminded me, Marty, I'm a scientist, so I must be scientific about this. I cautioned you about disrupting the continuum for your own personal benefit. Therefore, I must do no less. We shall proceed as planned, and as soon as we return to 1985, we'll destroy this infernal machine. Traveling through time has become much too painful.

Marty McFly: [shouts into the walkie-talkie] Doc! The red log's about to bloooooooooooooooooow!

[after the duel between Buford Tannen and Marty, which ended with Buford landing in green horse dung]
Seamus McFly: [chuckling to himself] That was good.

[Marty and Doc meet for the first time in 1885, just as Doc has saved Marty from being hung to death]
Marty McFly: [weakly] Doc?
Doc: [boldly] Marty? I gave you explicit instructions not to come here, but to go directly back to 1985.
Marty McFly: [weakly] I know, Doc. But I had to come.
Doc: Well, it's good to see you, Marty.
[the two hug and then walk off and Doc adds]
Doc: Marty, you're going to have to do something about those clothes. You walk around town dressed like that, you're liable to get shot.
Marty McFly: [gesturing a rope around his neck, weakly] Or hanged.
Doc: What idiot dressed you in that outfit?
Marty McFly: [smiles weakly] You did.

Bartender: [On the day Marty is set to face Buford in a shootout] Seamus! I didn't expect to see you here this early!
Seamus McFly: Aye. But somethin' told me I should be here, as if my future had something to do with it.

[after the DeLorean is smashed to bits by a freight train upon Marty's eventual return to 1985]
Marty McFly: [sadly] Well, Doc, it's destroyed. Just like you wanted.

[Doc is scornful about the idea of falling in love]
Marty McFly: Aw, come on, Doc, it's not science! When it happens, it just hits you. It's like lightning!
Doc: [shudders] Marty, please don't say that!

Marty McFly: [TV Version] Yeah. You think I was stupid enough to race that butthead?

Back to the Future Part II (1989)
[Flying above Biff in 1955]
Marty McFly: There he is, Doc! Let's land on him, we'll cripple his car.
Doc: Marty, he's in a '46 Ford, we're in a DeLorean. He'd rip through us like we were tin foil.

Marty McFly: [Reading the newspaper from 2015] "Within two hours of his arrest, Martin McFly Jr. was tried, convicted and sentenced to fifteen years in the state penitentiary."? Within two hours?
Doc: The justice system works swiftly in the future now that they've abolished all lawyers.

[last lines]
Young Doc: No! It can't be; I just sent you back to the future!
Marty McFly: No, I know; you *did* send me back to the future. But I'm back - I'm back *from* the future.
Young Doc: Great Scott!
[Doc faints]
Marty McFly: Doc! Doc! Doc! Oh, fantastic.

Biff Tannen: That's about as funny as a screen door on a battleship.
Marty McFly: [under his breath] It's "screen door on a submarine," you dork.

Marty McFly: That's right, Doc. November 12, 1955.
Doc: Unbelievable, that old Biff could have chosen that particular date. It could mean that that point in time inherently contains some sort of cosmic significance. Almost as if it were the temporal junction point for the entire space-time continuum. On the other hand, it could just be an amazing coincidence.

Marty McFly: [picks up a newspaper] 1985... it can't be...
[shotgun cocks behind him]
S. S. Strickland: Drop it!
[Marty drops the newspaper]
S. S. Strickland: So you're the son of a bitch who's been stealing my newspapers.
Marty McFly: Mr. Strickland! Mr. Strickland. It- it- it's me, sir. It's Marty!
S. S. Strickland: Who?
Marty McFly: [terrified] Marty McFly! Marty McFly! Don't you know me, sir? From school, sir!
S. S. Strickland: I've never seen you before in my life, but you look to me like a slacker!
Marty McFly: Yeah! That's right! That's right, I am a slacker! Don't you remember, you gave me detention last week!
S. S. Strickland: Last week? The school burned down six years ago! Now you got exactly three seconds to get off my porch with your nuts intact! One!
Marty McFly: [screams] Oh, please! Mr. Strickland! I just wanna know what the hell's going on here!
S. S. Strickland: Two!
Marty McFly: [covers groin] Ahhhhh!
[gang members in a truck round the corner]
Gang Member: Hey, Strickland!
[they do a drive-by]
Marty McFly: [covering his ears] Ah! Ah! Oh! Oh!
[jumps over porch]
S. S. Strickland: [fires two rounds] Eat lead, slackers!

Skinhead: You're coming with us upstairs!
Marty McFly: [struggling to get free] Let me go!
Match: [grabbing Marty] Sonny, we can do this the *easy* way or the *hard* way!
[3-D hits Marty over the head]
Miscellaneous voice: The easy way.

Marty McFly: [seeing a holographic ad for "Jaws 19"] Shark still looks fake.

Lorraine Baines: [frowns at a stuttering Marty] Are you all right?
Marty McFly: [stares at his mother's obviously enlarged breasts] I'm fine, I'm fine. It's just that you're so... you're so... big.

Marty McFly: What about the police, Biff? They're gonna match up the bullet with that gun.
Biff Tannen: Kid, I own the police! Besides, they couldn't match up the bullet that killed your old man.
Marty McFly: You son of a...
[Biff cocks the gun]
Biff Tannen: I suppose it's poetic justice - two McFlys with the same gun.

Marty McFly: Nice shot Doc! You're not gonna believe this, we gotta go back to 1955.
Doc: I don't believe it!

Marty McFly: Where are we? When are we?
Doc: We're descending toward Hill Valley, California, at 4:29 pm, on Wednesday, October 21st, 2015.
Marty McFly: 2015? You mean we're in the future?
Jennifer: Future? Marty, what do you mean? How can we be in the future?
Marty McFly: Uh, Jennifer, um, I don't know how to tell you this, but I... you're in a time machine.
Jennifer: And this is the year '2015'?
Doc: October 21st, 2015.

Marty McFly: The almanac. Son of a bitch stole my idea! He must have been listening when I- It's my fault! The whole thing is my fault. If I hadn't bought that damn book, none of this would have ever happened.
Doc: Well, that's all in the past.
Marty McFly: You mean the future.
Doc: Whatever! It demonstrates precisely how time travel can be mis-used, and why the time machine must be destroyed, after we straighten all of this out.

Marty McFly: I don't get it, Doc. I mean, how can all this be happening? It's like we're in Hell or something.
Doc: No, it's Hill Valley. Although I can't imagine Hell being much worse!

Marty McFly: I had a horrible nightmare. It was terrible.
Lorraine Baines: Well, you're safe and sound now. Back on the good old 27th floor.
Marty McFly: 27th floor?

Marty McFly: 'Cubs win world series... against Miami'?
Old Terry: Yeah, it's something, huh? Who would've thought? 100 to 1 shot! I wish I could go back to the beginning of the season, put some money on the Cubs.
Marty McFly: I just meant that Miami- What did you just say?
Old Terry: I said I wish I could go back to the beginning of the season, put some money on the Cubbies!

[Biff has chased Marty to the roof of a building]
Biff Tannen: Go ahead, kid! Jump! A suicide will be nice and neat.
Marty McFly: What if I don't?
[Biff points gun at Marty]
Biff Tannen: Lead poisoning.

Doc: They're taking her home, to your future home! We'll arrive shortly thereafter, get her out of there and go back to 1985.
Marty McFly: You mean, I'm gonna see where I live? I'm gonna see myself as an old man?
Doc: No, no, no Marty, that could result in a-
Doc: Great Scott! Jennifer could conceivably encounter her future self! The consequences of that could be disastrous!
Marty McFly: Doc, what do you mean?
Doc: I foresee two possibilities. One, coming face to face with herself 30 years older would put her into shock and she'd simply pass out. Or two, the encounter could create a time paradox, the results of which could cause a chain reaction that would unravel the very fabric of the space time continuum, and destroy the entire universe! Granted, that's a worse case scenario. The destruction might in fact be very localized, limited to merely our own galaxy.
Marty McFly: Well, that's a relief.

[answering the phone]
Middle-Aged Marty: Hey, Needles.
Needles: So, did you take a look at that little business proposal of mine?
Middle-Aged Marty: I don't know, Needles.
Needles: What are you afraid of? If this thing works it'll solve all your financial problems.
Middle-Aged Marty: And if it doesn't work Needles, I could get fired! It's *illegal*! I mean, what if the Jitz is monitoring, huh?
Needles: The Jitz'll never find out!
Middle-Aged Marty: Oh, ha, ha.
Needles: Come on... Stick your card in the slot and I'll handle it. Unless you want everyone in the division to think you're *chicken*.
Middle-Aged Marty: [angrily] Nobody calls me 'chicken', Needles. Nobody!
Needles: All right, prove it.
Middle-Aged Marty: All right, all right Needles. Here's my card. Scan it, I'm in.
Needles: Thanks McFly, I'll see you at the plant tomorrow.

Iko 'Jitz' Fujitsu, Marty's Boss in 2015: [shouts] McFly!
Middle-Aged Marty: Fujitsu-san, Konnichiwa.
Iko 'Jitz' Fujitsu, Marty's Boss in 2015: McFly, I was monitoring that scan you just interfaced. You are *terminated*!
Middle-Aged Marty: Terminated? No, no, it wasn't my fault sir! It was Needles, Needles was behind the whole thing!
Iko 'Jitz' Fujitsu, Marty's Boss in 2015: And you cooperated!
Middle-Aged Marty: No, I didn't, ah, it was a sting operation.
Iko 'Jitz' Fujitsu, Marty's Boss in 2015: It was illegal, and you knew!
Middle-Aged Marty: I was - I was - I was setting him up.
Iko 'Jitz' Fujitsu, Marty's Boss in 2015: McFly, read my fax!
Middle-Aged Marty: No! Please! No! I cannot be fired, I'm fired! Oh!
[Fax comes out saying "YOU'RE FIRED!" on three different machines, In concern, Jennifer takes one of the copies]
Middle-Aged Marty: Oh, this is heavy.
[crumples a copy of the fax against his forehead]
Middle-Aged Marty: What am I gonna tell Jennifer?

[after leaving Jennifer on her front porch swing in the Alternate 1985]
Marty McFly: I don't remember bars bein' on these windows...

Marty McFly: [referring to Alternate 1985 Biff] How could he be your husband? How could you leave dad for him?
Old Lorraine: Leave dad? Marty, are you feeling all right?
Marty McFly: [shouting] No! No I'm not feeling all right! I don't understand one damn thing that's goin' on around here and why nobody can give me a simple straight answer!
Old Lorraine: Oh, they must have hit you over the head hard this time.
Marty McFly: Mom, I just wanna know one thing. Where's my father? Where's George McFly?
Old Lorraine: Marty... George... Your father is in the same place he's been for the past 12 years... Oak Park Cemetery.

Old Lorraine: Aren't you and Jennifer getting along?
Middle-Aged Marty: Oh, yeah, great Mom. We're like a couple o' teenagers, ya know?

Marty McFly: Tough break, kid. Must be rough bein' named after a complete butthead.
Marty McFly: What's that supposed to mean?
Marty McFly: [Biff knocks on Marty's head with his cane]
Marty McFly: Hello? Hello? Anybody home? Huh? Think, McFly! Think! Your old man, Mr. Loser?
Marty McFly: What?
Old Biff: That's right. Loser with a capital "L".
Marty McFly: Look, I-I happen to know George McFly is not a loser...
Old Biff: [interrupts him] I'm not talkin' about George McFly. I'm talkin' about his kid! Your old man, Marty McFly Sr.? The man who took his life and flushed it completely down the toilet.
Marty McFly: I did? I - I mean - I mean he did?

Marty McFly: The answer's no, Griff.
Griff Tannen: No?
Marty McFly: Yeah, what are you deaf and stupid? I said "NO!"
Griff Tannen: What's wrong, McFly. Chicken?

Western Union Man: Kid, you all right? You need any help?
Marty McFly: There's only one man who can help me.

Marty McFly: Are you two related?
Biff Tannen: [knocking on Marty's head] Hello? Hello? Anybody home? What do you think? Griff just called me Grandpa for his health?

[Doc and Marty in the time machine are about to depart from the Alternate 1985]
Doc: Time circuits on.
Marty McFly: What do you mean "Time Curcuits on"? Doc, we're not goin' back now!
Doc: Yep.
Marty McFly: Doc, What about Jennifer? What about Einstein? We can't just leave 'em here.
Doc: Don't worry, Marty. Assuming we succeed in our mission, this alternate 1985 will be changed back into the real 1985, instantaneously transforming around Jennifer and Einie. Jennifer and Einie will be fine, and they will have absolutely no memory of this horrible place.
Marty McFly: Doc... what if we don't succeed?
Doc: We *must* succeed.

[Marty and Doc have just arrived back in 1955]
Doc: Sometime today, old Biff will show up to give young Biff the Almanac. Above all, you must not interfere with that event. We must let Old Biff believe he succeeded, so that he'll leave 1955 and bring the DeLorean back to the future.
Marty McFly: Right.
Doc: Once Old Biff is gone, grab the Almanac anyway that you can. Remember, both of our futures depend on this.
Marty McFly: You don't have to remind me of that, Doc.

Lorraine Baines: What the hell do you care? We can afford it! The least we can do with all that money is provide a better life for our children!
