The Dark Knight

The Joker:
"You won't kill me out of some misplaced sense of self-righteousness...and I won't kill you because...you're just too much fun."

The Joker:
"See, I'm a man of simple tastes. I like gunpowder...and dynamite...and gasoline! Do you know what all of these things have in common? They're cheap!"

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

Alfred:
"I suppose they'll take me in as well, as your accomplice. "
Bruce Wayne:
"Accomplice? I'm going to say the whole thing was your idea."

Alfred:
"Were you mauled by a tiger?"
Bruce Wayne:
"It was a dog... "
Alfred:
"Huh?"
Bruce Wayne:
"It was a big dog!"

The Joker: [to Batman]
"We really should stop fighting, we'll miss the fireworks!"
