Producer on Batman Begins Charles "Chuck" Roven has been talking to Superherohype about the sequel The Dark Knight which is due in June 2008.He said "One of the things that we have always done--we did it with the first 'Batman movie in which we were involved, 'Batman Begins'" he explained, "[is] we don't comment on any rumors because it takes all the fun away."
He did however talk a little about Heath Ledger joining the cast. "We're really thrilled about Heath Ledger playing The Joker. As Chris Nolan said, the great thing about Heath is he commits himself fully and totally to everything he does. He's just a brilliant, brilliant actor and you know this Joker is a very interesting dark fellow."
How so we asked? "You're going to have to wait on that," Roven laughed.
As far as confirming who will be back for the sequel, he did confirm Christian Bale as we already know, but was very vague when it came to anyone else. "We are hoping, depending upon everyone's schedule and other aspects of what it is they want to do with their careers, that we're going to get most if not all of them who are alive back. Meaning "alive in the movie", not really alive
