I’ve just found out that Christopher Nolan, the director of Batman Begins and The Dark Knight, has another Batman project in the works. The project is currently titled Untitled Batman project, but I think it’s safe to say that it’s the sequel to The Dark Knight.
As for casting, I do know that Christian Bale, Michael Caine and Gary Oldman are all under contract for three films. There is also a rumor floating around that Harvey Dent “Two-Face” played by Aaron Eckhart will be returning for the third film (that’s only a rumor though).
The other rumors I’ve heard all have to do with the possible villains. I know that Catwoman is a very strong possibility and so is The Riddler, fans have also been asking to see The Penguin once again on the big screen and there is also talk that they might recast The Joker (which I don’t want to happen).
I’ll keep you updated with any information I receive.
