Back to the Future
Movie Quote Quiz

Dr. Emmett Brown: 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 buy plutonium. Did you rip that off?
Dr. Emmett Brown: Shhhhhh. 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 shiny bomb-casing full of used pinball machine parts!

[Doc is wearing his thought reading device.]
Marty McFly: Doc, 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 this means? It means that this damn thing doesn't work at all!

Marvin Berry: Chuck. Chuck! It's Marvin - your cousin, Marvin BERRY. You know that new sound you're looking for? Well, listen to this!

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.

Biff Tannen: Why don't you make like a tree and get out of here!

[Lorraine's parents are talking about Marty McFly, Lorraine's future son.]
Stella Baines: He's a very strange young man.
Sam Baines: He's an idiot. Comes from upbringing. His parents are probably idiots too. Lorraine, if you ever have a kid that acts that way I'll disown you.

Marty McFly: Jesus, George, it was a wonder I was even born.

Doc: Next Saturday night, we're sending you Back to the Future!

Marty: Jeez, Doc. You disintegrated Einstein!
Doc: Don't worry, Marty. Einstein is perfectly fine.
Marty: Well then where the hell is he?
Doc: I think the appropriate term is WHEN the hell is he.

Doc: The only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.
Marty: What?
Doc: A bolt of lightning! Unfortunately, you never know when or where it's ever going to strike!
[Marty holds out the "Save the Clock Tower" flyer.]
Marty: We do now.

Biff: Why don't you make like a tree, and get out of here?

Marty: Doc look, all we need is a little plutonium!
Doc: Oh! I'm sure that in 1985, plutonium is available at every corner drug store, but in 1955 it's a little hard to come by. Marty, I'm sorry, but I'm afraid you're stuck here.

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

Back to the Future mistake picture

Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)

Trivia: The farm where Marty arrives in 1955 belongs to a man called Peabody, and he calls his son Sherman; the names are a tribute to "Sherman and Mr. Peabody," two cartoon time travellers from a 1960s American TV show.

More trivia for Back to the Future

Question: Right when Marty gets back to Doc before he goes back to 1985, he's praising his dad's actions of the night. One line that's bothered me ever since I can remember is "My dad laid out Biff. He's never stood up to Biff in his life." And then the Doc pauses for a second and gets a strange look on his face and says, "Never?" To that, Marty says, "No, why?" and the Doc shrugs it off saying, "Nevermind." What's Doc thinking? The best I can come up with is that he's wondering what effects it'll have on the future, but that's a rough guess. If anyone out there knows, I'd be happy to hear it.

DenizenZERO

Chosen answer: I think that is *exactly* what he is thinking. He realizes that by standing up to Biff, George may have irrevocably changed his personal future, and therefore affected Marty's future as well. This is exactly the sort of thing Doc was so eager to prevent by refusing to hear any information about the future.

Phil C.

Answer: It would have had to be something that would have happened anyway without the interference, otherwise Marty wouldn't have originally existed.

Answer: In the novel Marty adds that George is also thinking about college now. Doc says that this might delay Loraine and George having kids for awhile and adds that Marty might find himself like 10-14 years old when he gets back to 1985.
