Mischa Barton wants to strip naked on screen.

The 'St. Trinian's' star has no problem baring all if the role requires it, but claims she just hadn't the opportunity yet.

Mischa, 21, said: "I don't mind nudity. I just don't do it that often. It depends on the film and if I trust the director and if the context is emotional or just sexual."

The actress is rumored to have been offered the starring role in the new 'Supergirl' movie, and admits she would love to play the sexy heroine.

She said: "It would be pretty awesome. But everybody in Hollywood goes up for those films. I haven't been offered anything."

The former star of 'The O.C.' has also spoken about her last appearance as rebellious teenager Marissa Cooper in the hit US TV show.

Mischa admits she loved filming Marissa's car crash death scene and kept demanding it be made gorier.

She added to Maxim magazine: "You have no idea how much fun I had doing that scene. I was on the set, yelling, 'More blood! More blood!' She needed to go out with a bang."
