The ending of this summer’s Batman Begins suggested that the next bad guy that Christian Bale’s Caped Crusader will face will be the Joker. But who will follow in the footsteps of Jack Nicholson and Cesar Romero to play the grinning villain? Warner Bros. tells PopWatch that no one has been cast yet, but a group of online petitioners would like to see the role go to Charlie’s Angels‘ Creepy Thin Man, Crispin Glover (left). He’d certainly be a good choice, though I still think it would be great if the role went to the TV-cartoon Joker, Mark Hamill. Adrien Brody’s name has also been mentioned; he certainly has the right skeletal jack-in-the-box look.

What say you, PopWatchers? Will you endorse Glover, or do you prefer some other Joker?
