Sir Michael Caine appeared on BBC Radio 1's The Chris Moyles Show on Wednesday to promote his autobiography "The Elephant to Hollywood" and talk turned to director Christopher Nolan's third Batman movie.
He said the movie will "probably start in May next year..." Asked if he will be part of the cast, he said, "I assume I'm there. In the movie business, you never believe anything, you assume."
He added that Chris and co-writer Jonathan Nolan are not telling anyone who the villain will be in the new film.
In related news, Chris Nolan confirmed to Empire today that he is indeed directing, in case you had any doubts.
Warner Bros. Pictures is targeting a July 20, 2012 release date for the film.
