Michael Caine has admitted to getting into trouble with director Christopher Nolan about giving too much information away about The Dark Knight Rises.
Security on the third and final part of Nolan's Batman trilogy is exteremely tight, with no information whatsoever being able to leave the set.
Caine told The Daily Express: "I'm lucky to be able to mention the title. I've already got in trouble for mentioning I'm working on it and that we're filming. Chris phoned saying, 'Why did you say that? You shouldn't have said that!"
The veteran actor will no doubt be wise to hold his own counsel between now and the movie's release date.
The Dark Knight Rises, which sees Christian Bale reprising his role as the Caped Crusader, is released on July 20, 2012.
