Marty McFly • Seamus McFly
- 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.
- 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?
- 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.
- [last lines]
- Marty McFly: Hey, Doc! Where you goin' now? Back to the future?
- Doc: Nope. Already been there.
- [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.
- [pause]
- 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.
- Doc: You're just not thinking fourth dimensionally!
- Marty McFly: Right, right. I have a real problem with that.
- Doc: So, it may not be my name that's supposed to end up on this tombstone. It may be yours.
- [Marty and Doc exchange expressions they have each been saying throughout the trilogy...]
- Marty McFly: Great Scott!
- Doc: I know, this is heavy.
- Young Doc: [looking at a tiny circuit under a magnifying glass] Unbelievable that this little piece of junk could be such a big problem. 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 has accepted Buford's challenge to a duel]
- Buford "Mad Dog" Tannen: Then let's finish it, right now!
- Buford's Gang Member #1: Oh, uh, not now, Buford. Uh, Marshal's got our guns.
- Buford "Mad Dog" Tannen: Like I said, we'll finish this tomorrow.
- Buford Tannen's Gang #3: Tomorrow, we're robbin' the Pine City Stage.
- Buford "Mad Dog" Tannen: What about Monday? 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!
- [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 drives the DeLorean to 1885, an actual group of Native Americans is literally running towards his location]
- Young Doc: [shouting frantically]
- Marty McFly: Indians!
- 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.
- 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.
- [1885 - Marty walks into a saloon, dressed in the outfit that Doc Brown gave him in 1955]
- Levi: Take a look and see what just breezed in the door.
- Zeke: Why, I didn't know the circus was in town.
- Jeb: 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]
- Jeb: 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.
- [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 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!
- 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]
- 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.
- 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?
