Harvey Dent: The famous Bruce Wayne. Rachel's told me everything about you.
Bruce Wayne: I certainly hope not.

Gotham National Bank Manager: The criminals in this town used to believe in things. Honor. Respect. Look at you! What do you believe in? What do you believe in!
The Joker: I believe whatever doesn't kill you simply makes you... stranger.

Happy: So why do they call him "The Joker"?
Dopey: I heard he wears make-up.
Happy: Make-up?
Dopey: Yeah, to scare people. You know, war paint.

Harvey Dent: Alfred, right?
Alfred Pennyworth: That's right, sir.
Harvey Dent: Rachel talks about you all the time. You've known her for her whole life.
Alfred Pennyworth: Not yet, sir.
Harvey Dent: Any psychotic ex-boyfriends I should be aware of?
Alfred Pennyworth: [smiles] Oh, you have no idea.

The Joker: It's the schemers that put you where you are. You were a schemer, you had plans, and uh, look where that got you. I just did what I do best. I took your little plan and I turned it on itself. Look what I did to this city with a few drums of gas and a couple of bullets. You know what I noticed? Nobody panics when things go according to plan. Even if the plan is horrifying. If tomorrow I tell the press that like a gang banger will get shot, or a truckload of soldiers will be blown up, nobody panics, because it's all, part of the plan. But when I say that one little old mayor will die, well then everyone loses their minds!

The Joker: Introduce a little anarchy. Upset the established order, and everything becomes chaos. I'm an agent of chaos. Oh, and you know the thing about chaos? It's fear.

[with the gun in Two-Face's hand, Two-Face pauses and takes out his coin]
Two-Face: [showing the unscarred side] You live.
The Joker: Mm-hmm.
Two-Face: [flips, showing the scarred side] You die.
The Joker: Mmm, now we're talking.

The Chechen: What do you propose?
The Joker: It's simple, we, uh, kill the Batman.
[Mobsters laugh]
Salvatore Maroni: If its so simple, why haven't you done it already?
The Joker: If you're good at something, never do it for free.

James Gordon Jr.: Did Batman save you, daddy?
Lt. James Gordon: Actually, this time I saved him.

Lucius Fox: Let me get this straight: You think that your client, one of the wealthiest, most powerful men in the world, is secretly a vigilante who spends his nights beating criminals to a pulp with his bare hands. And your plan is to blackmail this person? Good luck.

Bruce Wayne: I need a new suit.
Lucius Fox: Yeah, three buttons is a little '90's, Mr. Wayne.
Bruce Wayne: I'm not talking fashion, Mr. Fox, so much as function.
[hands him a diagram]
Lucius Fox: You want to be able to turn your head.
Bruce Wayne: Sure would make backing out of the driveway easier.
