Actor Christian Bale told MTV that fans should expect a more realistic portrayal of The Joker as opposed to some of the other more over-the-top interpretations of the character in previous incarnations.

"I think I should let Heath [Ledger] give you the answer on all this," said Bale.  "Certainly I think that we dig a little more than the other movies did...We recognize, of course, they are cartoon characters, [but] we try to ground them in somewhat more reality than the other movies."
