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."

The 33-year-old Oscar winner is now hoping to break away from making serious movies and experiment with lighter projects.

Charlize said on British TV show "Richard and Judy": "The next one has to be a comedy. I've always let it be known that I would love to do a musical."

The blonde beauty recently revealed she would love to team up with Will Smith for a sequel to superhero movie "Hancock".

She said: "If everybody was on board, yeah, I'd do it. I would be an idiot not to do it. Riding the Will Smith train is a really nice train to ride."
