In an interview with BBC News, Gary Oldman, who portrays Commissioner Gordon, admitted to misplacing his personal screenplay for the Batman sequel.
"I was in a panic for 20 minutes... I thought, 'Where the hell have I put it?' It had my name on it. They would have killed me."
Lucky for Oldman, he found the script in his hotel room later in the evening.
"I'd gone out for dinner and I had put it in the room between the mattress and the bed, because I couldn't scrunch it into the safe. I was half-thinking about something else and shoved it there," said Oldman.
Despite the secretive methods for protecting the film, there have been plenty of on-set photos from "TDKR" popping up on the Web. For now, however, plot details for the highly anticipated sequel have been left intact.
