Charlize Theron happy to bare all

Charlize Theron finds it easy to go naked on screen.

The actress found it harder to convey her character's emotion in new movie 'The Burning Plain' - in which she plays a self-abusing, sex addicted mother - than take her clothes off.

She said: "Being naked is one of those things I think people think of in an isolated, compartmentalised way, but sometimes it's harder to do a scene where you have to bear a raw emotion of pain or vulnerability.

"That kind of nakedness is sometimes much harder than taking your clothes off."

Oscar winner Charlize, who co-produced 'The Burning Plain', also revealed she never thought she would ever step behind the camera on her films.

The 33-year-old star added: "If you' asked me ten years ago if I would produce, I probably would have said, 'You're crazy.' But it's become one of those things that the older I've gotten and the more I've done this, the more I realise I love film making.

"It's not the idea of playing a role and showing up and just acting and doing my thing, it's the collaborative aspect of it that I really love."
