Actor Heath Ledger will play 'The Joker', based on the DC Comics villain, in director Chris "Memento" Nolan's 'Batman' sequel "The Dark Knight", starting January 2007."It's definitely going to stump people," Ledger told the Toronto Sun.
"I think it'll be more along the lines of how 'the Joker' was meant to be in the comics...
"Darker and more sinister."
