The actor returns as the iconic British spy in the upcoming film and he promises 007 fans the character is tested even more than he was in his previous films 'Casino Royale' and 'Quantum of Solace'.
He told the new issue of Empire magazine: "He's always out of his f***ing comfort zone! Hanging off the top of some kind of structure somewhere, I don't know how comfortable that ever is. I know for me how uncomfortable it is, pushing him, I think, is the best way to describe it.
"We're just pushing the characters, physically and emotionally, as far as we can in the context of a Bond movie."
Although very little is known about the plot of the film, it sees Bond pitted against bad guy Silva, played by Javier Bardem, who was very happy with the role director Sam Mendes has given him to play.
Javier said: "The material is great and the story very powerful and complex. Sam gave me a version of Silva and I was like, 'Hmmm, that's very interesting, this is gonna be fun.' As I say, there is meat to chew."
