Heath Ledger
The Dark Knight: Hospital Scene
INT. HOSPITAL ROOM - DAY

JOKER: Hi.

The Joker draws closer to Dent's bed. Dent strains at the leather cuffs binding him to the bed.

JOKER: Y'know, I don't want there to be any hard feelings between us, Harvey.

The Joker loosens Dent's restraints.

JOKER: When you and, uh...

HARVEY DENT: RACHEL!

JOKER: ...Rachel were being abducted, I was sitting in Gordon's cage. I didn't rig those charges.

DENT: Your men. Your plan.

JOKER: Do I really look like a guy with a plan?

Dent's hand is trembling.

JOKER: You know what I am? I'm a dog chasing cars. I wouldn't know what to do with one if I caught it!

Y'knnow I just do things. The mob has plans. The cops have plans. Gordon's got plans. Y'know they're schemers. Schemers trying to control their little worlds. I'm not schemer. I try to show the schemers how pathetic their attempts to control things really are. So when I say that you and your girlfriend was nothing personal, you know I'm telling the truth. 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, hmm? You know what I noticed? Nobody panics when things go according to plan. Even if the plan is horrifying. If tomorrow I told the press that, like, a gang-banger would 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 everybody loses their minds!

Hands him the pistol. Dent holds it to the Joker's head.

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?

Dent looks into the Joker's eyes. Finding meaning.

JOKER: It's fair.

Dent looks down at the coin in his hands. Turns it over, feels it's comforting weight. Shows the Joker the good side.

DENT: You live.

He turns the coin over. The flip side is deeply scarred.

DENT: You die.

The Joker looks at the coin. Looks at Dent, admiringly.

JOKER: Now we're talking.
