Modest actress Freida Pinto requested a body double for one steamy scene in new movie epic Immortals because she refused to bare her backside.

The Slumdog Millionaire star plays a priestess who romances Henry Cavill's character Theseus, the king of Athens, in the film.

The two stars' characters enjoy a tryst in the movie - but Pinto reveals it isn't her backside cinemagoers will see in their love scene.

She tells Eonline.com, "It wasn't really my butt. It was a butt double. I'm relieved I don't have to deal with that issue."
