• I'm sure that in 1985 plutonium is available in every corner drug store, but in 1955 it's a little hard to come by.

Dialogue

Mr. Strickland: 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: Can I go now, Mr. Strickland?

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: Yeah, well, history is gonna change.

Lorraine: I don't like her, Marty. Any girl who just calls up a boy is just asking for trouble.

Linda: Oh, Mom, there's nothing wrong with calling a boy.

Lorraine: I think it's terrible! Girls chasing boys. When I was your age I never chased a boy or called a boy or sat in a parked car with a boy.

Linda: Then how am I supposed to ever meet anybody?

Lorraine: Well, it will just happen, like the way I met your father.

Linda: That was so stupid! Grandpa hit him with the car.

Marty: Wait a minute. Wait a minute Doc, uh, are you telling me you built a time machine... out of a DeLorean?

Doc Brown: The way I see it, if you're going to build a time machine into a car, why not do it with some style?

Marty: Sorry about your barn. (Old Man Peabody tries to shoot him)

Sherman Peabody: It's already mutated into human form, shoot it!

Old Man Peabody: Take that, you mutated son of a bitch!

Doc Brown: Tell me, Future Boy, who's President of the United States in 1985?

Marty: Ronald Reagan.

Doc Brown: Ronald Reagan? The actor? Then who's vice-president, Jerry Lewis? I suppose Jane Wyman is the First Lady? And Jack Benny is Secretary of the Treasury!

Marty: This is heavy, Doc.

Doc 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?

George: I don't know what I should say.

Marty: Well say anything, George. Say the first thing that comes to your mind.

George: Nothing's coming to my mind.

Marty: Jesus, George. It's a wonder I was ever born.

Marty: What about all that talk about screwing up future events? The space-time continuum?

Doc Brown: Well, I figured, what the hell!

Taglines

• Meet Marty McFly. He's broken the time barrier. Busted his parents' first date. And, maybe, botched his chances of ever being born.

• 17 year old Marty McFly got home early last night. 30 years early.

• Marty McFly just broke the time barrier. He's only got one week to get it fixed.

• Marty McFly's having the time of his life. The only question is -- what time is it?

• He was never in time for his classes... He wasn't in time for his dinner... Then one day... he wasn't in his time at all.

• Bumping into your parents is no big deal unless you bump into them before you were born.
