Trivia: When the Joker crashes Bruce's party and threatens Rachel with the knife, it was the first time Maggie Gyllenhaal had seen Heath Ledger in his make-up. When the Joker cups her face in his hand and says "look at me", that was improvised by Ledger because Gyllenhaal was so frightened by his appearance that she was trying to look away.
