For those who missed it, here's what Christian Bale had to say about The Joker in Total Film magazine:
But the main attraction is a villain whose "taste for theatrics" was so memorably portrayed by Jack Nicholson in Tim Burton's Batman. The Joker is back. And it's no laughing matter.
"It's a much more anarchic, punk rock, almost junkie version of it," says Bale, f Heath Ledger's disturbing take on Batman's deadliest foe. "He's the kind of psycho kid that just will do anything and has absolutely no conscience and morals - I think they've done a real nice job with his look. It's certainly a whole lot more dangerous; there's a bit of Clockwork Orange there, a bit of Sid Vicious, a whole lot of great, anarchic personalities blended within The Joker."
