Actor Michael Caine, who plays Alfred in Christopher Nolan's Batman series, believes that with Heath Ledger's passing the character of The Joker should be retired from any future caped crusader films.
"I asked him, 'What’s it about?' and he said, 'The Joker.' I said, 'Oh, shoot. Jack Nicholson was so great. How will you top that?' He said, 'I’m going to try.' But when he told me it was going to be Heath Ledger, for some reason I just said, 'That will be fine, then.' Besides, you wouldn’t want to be the guy to try to outdo Jack and Heath," the actor told USA Today.
As for who he thinks should be the next villian? Caine's suggestion is The Riddler.
