Charlize Theron finds it easy to bare it all 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, compartmentalized way, but sometimes it's harder to do a scene where you have to bear a raw emotion of pain or vulnerability."

Charlize Theron is sick of being linked with "doom and gloom." The South African-born actress - who played a serial killer in "Monster" and a mine worker who was sexually harassed in "North Country" - accepts her most famous movies have involved depressing storylines.

Charlize - who portrays a woman with a troubled childhood in new movie "The Burning Plain" - said: "I am starting to figure that if there is a woman in a doom and gloom scenario, my name comes up."
