Daniel Craig thinks he's getting too old to play James Bond

Asked how long Bond can keep going, he said: "He's old now - 47. He'll keep going for as long as he's physically able, which isn't that long.

"I'm contracted for one more film, which seems to be a fair number, but I'm not going to make predictions."

And though Daniel thinks it would be possible to remake some of the classic Bond movies, he's ruled himself out of any such project because of his age.

He said: "I don't think [I'd remake one]. I guess you could because all the movies come from the books in which there are so many characters and stories and different angles to explore. But no, I'm too old."

And Daniel admitted it is getting more and more difficult to get into the shape required for the action films.

Asked how he prepares, he told Britain's HELLO! magazine: "Nothing special - the usual exercising, working myself to death. No secret method involved, just sheer hard graft that I'm used to. It's getting harder I will admit but such is life."
