Getting back to the roots of darkness in the "Dark Knight". Not your 60's Batman anymore. The role of the Joker definitely changes in this film vs. the classic portrayals of Romero and Nicholson. Ledgers Joker is more true to the original pyscopath intended. It is a remarkable job of acting. Ledger never broke from his portrait of the Joker, he maintained every quirk and tick throughout the film. For once all the hype was on target and Ledgers Joker will be remembered!
