A decade after Michael Caine first collaborated with Christopher Nolan, the actor says his director friend and regular movie collaborator is at work on a new screenplay ? only not even Caine knows if there?ll be a role for him. Caine said recently in an interview, "He?s got a new movie. I had dinner with him last night and he?s all secretive, and he never told me a thing. I don?t know if there?s a role for me even. He won?t tell me." Caine, who has worked with Nolan six times added that meeting the director marked an incredible change in his life.
