Chris Nolan wants Dark Knight rises finale to be kept secret

London: Director Christopher Nolan has refused to give out any scripts detailing the ending of The Dark Knight Rises as he wants to keep it a secret.

The 41-year-old is determined to keep the ending of his third Batman movie starring Christian Bale under wraps and is advising his cast on the story verbally in order to minimise the chance of leaks, reported Contactmusic.

Actor Gary Oldman, who plays Police Commissioner James Gordon in the film, said, "Christopher doesn't want anyone to ruin it and I completely understand that. The newer people on the film go to his office to read the script. They sent mine out, but it had to be hand delivered directly to me and nobody else. And the final few pages were missing. I went along and talked to Christopher and in person about the ending. Then I locked it away in my head," Oldman said.

The actor is happy with his role in the film and is pleased his career has moved on from the frenetic characters of his younger days.

"I was younger then, that's all. In 'The Dark Knight Rises' I'm the 50-year-old police commissioner while wonderful, young Heath Ledger is bouncing off the walls as The Joker. Now, had that part come along 15 years ago, people might have said, That's a Gary Oldman role," Oldman added.
