Daniel Craig says it's getting "harder and harder" to do nude scenes in James Bond movies.

The 44-year-old actor - who is returning for his third film as the iconic British spy in Skyfall - admits he has "fun" taking his clothes off while portraying the secret agent and hopes it adds some "sexiness" to the 007 film franchise: "I don't actually read those bits. I don't care how many times I have to do it. It's going to be harder and harder the older I get. It's just fun. There's enough sexiness in the movie with the girls - and hopefully me as well - but it's a little bit of a gag now."

Daniel stars opposite Javier Bardem in Skyfall and while he admits there was no free time to spend with the 43-year-old star - who portrays latest Bond villain Raoul Silva - during filming, he is keen to watch a game of rugby with the No Country For Old Men actor when they get a chance.

"He played rugby for Spain, so he's serious. It's funny, we never went together, but he went to the 6 Nations and I went to the 6 Nations when they were on. I got him tickets. He got me tickets. I'd love to go to watch a rugby game with him. There's just no time [to hang out], unfortunately. I'm on set every day. I wish we had more time. But we have a long year ahead of us, so hopefully we'll see each other in a more chilled state," he explained.

Daniel admits Javier has put in a "superb" performance as Raoul thanks to his knowledge of how a successful Bond villain should act. "Well, Javier is a brilliant actor, so that's taken care of. He knows what a Bond villain is and he's given it everything he's got, which is a lot, let me tell you," he added.
