Michael Caine appeared on BBC's The Chris Moyles Show earlier today, where he revealed that Batman 3, the highly anticipated sequel to The Dark Knight, will begin shooting this May.

The actor did not confirm that he would be appearing in the sequel, only saying, "I assume they'll ask me to be there. In the movie business, you never believe anything. You always assume." Michael Caine also made it clear that Christopher Nolan and his co-writer Jonathan Nolan know who the main villain will be, but they are not sharing that information with anyone at this time.

In related news, Christopher Nolan confirmed (as if there were any doubts) to Empire that he would in fact return to direct Batman 3. About directing the sequel, the director had this to say:

"It's becoming inevitable, I'll put it that way. I feel myself falling into it, I guess. And getting it all figured out and I'm pretty excited about what we're doing so... If I haven't announced it, I think that people probably all know at this point that I'm doing it. I think (I) can at this point, (say) yes."

Jonathan Nolan has written at least one draft of the Batman 3 screenplay, which Christopher Nolan is currently revising.
