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.

Dr. Emmett Brown: If my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit.

[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?

[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?

Dr. Emmett Brown: Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles per hour, the instant the lightning strikes the tower... everything will be fine.

[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.

Dr. Emmett Brown: [reads the "Save the Clock Tower" flyer and reacts with hope] This is it! This is the answer. It says here that a bolt of lightning is going to strike the clock tower at precisely 10:04 p.m. next Saturday night! If... If we could somehow harness this lightning... channel it into the flux capacitor... it just might work. Next Saturday night, we're sending you back to the future!

Dr. Emmett Brown: I'm sure that in 1985, plutonium is available in every corner drugstore, but in 1955, it's a little hard to come by.

[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]

[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.

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?

[repeated Line]
Dr. Emmett Brown: Great Scott!

[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: Things have certainly changed around *here*. I remember when this was all farmland as far the eye could see. Old man Peabody owned all of this. He had this crazy idea about breeding pine trees.

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]

[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.

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.

Dr. Emmett Brown: [holding Marty's video camera] No wonder your president has to be an actor. He's gotta look good on television.

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.

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.

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.

[pacing in front of the clock tower]
Dr. Emmett Brown: [looks at his watch] Damn! Where is that kid?
[looks at a small alarm clock in his other hand]
Dr. Emmett Brown: Damn!
[looks at a second watch on his other wrist]
Dr. Emmett Brown: Damn! Damn!

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.

Dr. Emmett Brown: You'll have to forgive the crudeness of this model. I didn't have time to paint it or build it to scale.

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]

Dr. Emmett Brown: Now, if my calculations are correct, when this baby hits 88 miles an hour, you're going to see some serious shit!

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.

Doc: The time-traveling is just too dangerous. Better that I devote myself to study the other great mystery of the universe: women!

Doc: Marty! What in the name of Sir Isaac H. Newton happened here?

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: 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!

Doc: Oh, and Marty, be careful around that Griff character. He's got a few short circuits in his bionic implants.

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.

[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.

Doc: Roads? Where we're going, we don't need roads.

Doc: I went to a rejuvenation clinic and got a whole natural overhaul. They took out some wrinkles, did hair repair, changed the blood, added a good 30 to 40 years to my life. They also replaced my spleen and colon. What do you think?

[repeated line]
Doc: Great Scott!

Marty McFly: Tell me about my future. I know I make it big, but do I become, like, a rich rock star?
Doc: Please Marty. No one should know too much about their destiny.

Marty McFly: [on walkie-talkie to Doc] Doc! Biff's guys chased me into the gym and their gonna jump... me!
Doc: [on walkie talkie to Marty] Then get outta there!
Marty McFly: [on walkie-talkie] No, Doc. Not *me*, the *other* me, the one that's up on stage playing "Johnny B. Goode."!
Doc: [on walkie-talkie] Great Scott! Your other self will miss the lighening bolt, you won't get back to the future and we'll have a major paradox!

Marty McFly: [arriving in 1955] Oh, this is heavy, Doc. I mean, it's like I was just here yesterday.
Doc: You were here yesterday, Marty.

Doc: Don't talk to anyone, don't touch anything, don't do anything, don't interact with anyone, and try not to look at anything.

Marty McFly: The future. Unbelievable. I gotta check this out, Doc.
Doc: All in good time Marty, we're on a right schedule here.
Marty McFly: Tell me about my future. I know I make it big, but do I become like a rich rock star or something?
Doc: Please, Marty, nobody should know too much about their own destiny.
Marty McFly: Right, right. But I am rich, right?

Doc: Don't talk to anyone, don't touch anything, don't do anything, don't interact with anyone, and try not to look at anything.
Marty McFly: I don't get it, I thought you said this has something to do with my kids.

Doc Brown: We've been swallowed!

Biff Tannen: [after short-circuiting the lab, and trapping Doc in his own office, he knocks] Hello! Hello! Dr. Brown!
Doc Brown: Biff! How in the blazes did you get here?
Biff Tannen: [revealing the tied up scientists] Why don't you ask these bozos?
Institute Scientist: [Biff removes the tape off of the scientist's mouth] Dr. Brown. Our team was conducting an experiment back in 1955.
Female IFT Scientist: He must have stowed away!
Biff Tannen: Hey! I'm not the one to pass on a free ride!

Doc Brown: Go fourth time travelers, and remember the future is what you make it!

Martin Seamus 'Marty' McFly: Well sure, because its a time machine.
Dr. Emmett Brown: Cause it's a DeLorean! These things are collectors' items.

Verne Newton Brown: Dad, Jules said he could use the computer, but now he won't let me.
Jules Erastosthenes Brown: But father, I have almost completed my calculations, and the delay would be intolerable! I'm computing the logarithmic equivalence of the atomic weight of certain isotopes found in the lampanide series of rare earth elements.
Dr. Emmett Brown: Again?
Verne Newton Brown: I'm trying to beat my all time score on 'The Legend of Bruno'.
Dr. Emmett Brown: Great soups I'm baffled! On the one hand Jules is on the eternal search for knowledge, on the other hand Verne is developing the hand-eye coordination which will come in handy in the world of the future.

Store Clerk: Uh...
[looks to the managers]

Doc Brown: Nothing.
Doc Brown: It's a weather experiment.
Albert: Oh.
[closes the door]
