Marty McFly: Whoa... they really cleaned this place up. Looks brand-new.
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.

Dr. Emmett Brown: Are those my clocks I hear?
Marty McFly: Yeah! Uh, it's 8 o'clock!
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.

arty McFly: Do you know where Riverside Drive is?
Sam Baines: It's on the other end of town, a block past Maple. East end of town.
Marty McFly: A block past Maple? That's John F. Kennedy Drive.
Sam Baines: Who the hell is John F. Kennedy?

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.

[introducing his band] All right. We're the, uh... we're the Pinheads.

George McFly: Do you really think I oughta swear?
Marty McFly: Yes, definitely. Goddamn it George, swear.

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!

Marty McFly: Ah, Jesus Christ! Jesus Christ, Doc, you just 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 is 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 am and zero seconds, we shall catch up with him and the time machine.

Dr. Emmett Brown: 1.21 jigawatts? 1.21 jigawatts! Great Scott!
Marty McFly: [following] What the hell is a jigawatt?

Wait, you don't understand. If you don't play there's no music. If there's no music they don't dance. If they don't dance they don't kiss and fall in love and I'm history.

Count Dooku: May I ask why a Jedi Knight is all the way out here on Geonosis?
Obi-Wan: I'm tracking a bounty hunter named Jango Fett. Do you know him?

Anakin: I'm a Jedi.
Watto: A Jedi. Whaddya know?
