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."
