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.

He said: ''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 explained: ''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.''

Daniel admits Javier has put in a ''superb'' performance as Raoul thanks to his knowledge of how a successful Bond villain should act.

He added to ShortList magazine: ''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.''
