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.
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!
Older Man on Train 1: I've never seen a man so broken up over a woman. What did he say her name was, Kara, Sarah?
Older Man on Train 2: Clara.
Clara Clayton: Excuse me.
Older Man on Train 1: Ma'am.
Clara Clayton: But was this man tall, with great big brown puppy dog eyes and long silvery flowing hair?
Older Man on Train 1: You know him?
Clara Clayton: Emmitt!
This reminds me of the time I attempted to reach the center of the earth. I'd be reading my favorite author, Jules Verne. I spent weeks preparing for the expedition, I didn't even get this far. Of course, I was only 12 at the time. It was the writings of Jules Verne that had a profound effect on my life. I was 11 when I first read 20,000 Leagues Under the Sea. That's when I realized that I must devote my life into science.Young Doc
Marty McFly: Hey, look, Frisbee. Far-out! [leaves]
Seamus McFly: Wonder what he meant by that?
Maggie McFly: It was right in front of him.
Maggie McFly: I hope you're considering your own future, Mr. Eastwood.
Marty McFly: I think about it all the time.
Marty McFly: Doc! Doc! Come quick!
Young Doc: What's the matter? You look like you've seen a ghost.
Marty McFly: You're not far off.
After as you get the time circuits fixed and put new tires on the DeLorean, I'm going back to 1885, and I'm bringing you home.Marty McFly
Gun salesman: Young man, young man! I'd like you to have this new Colt Peacemaker and gun belt. Free of charge.
Marty McFly: Free?
Gun salesman: I want everyone to know that the gun that shot Buford Tannen was a Colt Peacemaker.
Marty McFly: Hey, no problem. Thanks a lot!
Gun salesman: Of course, you understand, that if you lose I'm taking it back.
I don't dance very well when my partner has a gun in his hand.Clara Clayton
Young Doc: Well, good luck for both our sakes. You've made a real difference in my life. See you in the future.
Marty McFly: You mean the past?
Young Doc: Exactly.
Young Doc: All you got to do is drive directly toward that screen accelerating up to 88 miles an hour.
Marty McFly: Wait a minute, Doc. It I go driving straight towards that screen, I'm gonna crash into those Indians.
Young Doc: Marty, you're not thinking fourth dimensionally. You'll soon enough be transferred back into 1885, and those Indians won't even be there.
