In an interview with Newsweek, Heath Ledger sat down to discuss, amongst other things, his role in the upcoming Batman Begins sequel The Dark Knight.
Here is the section of the interview where the actor briefly touches on the role of playing Joker:
NW: As the Joker in the new “Batman” movie, have you tried on the mask yet?
HL: Metaphorically, yes. I’ve been bouncing around like a lunatic for four months. I definitely have a different take on him, but I’ve yet to do a proper makeup run. It’s on the agenda.
NW: Do you walk around the house all day practicing your laugh?
HL: I’d be lying if I said I haven’t been.
