James McAvoy was terrified filming sex scenes with Angelina Jolie

James McAvoy stars opposite Angelina in Wanted, a film based on Mark Miller's explosive novels.

He plays 25-year-old account worker Wesley Gibson, who is transformed from a loser, cheated on by his girlfriend and bullied by his boss, into a dark superhero.

James says he doesn't enjoy the sex scenes, however convincing they may seem on the big screen.

He said: "It's sweaty and uncomfortable.

"My paranoia is the girl I'm doing the sex scene with will think I'm getting off on her.

"I have nightmares about that the night before a sex scene. There's no chance of getting any kind of stimulus because you're so nervous and there's all these people watching you.

"It's daunting. They're considered to be the most beautiful people in the world, and I'm clearly not. I don't think I've been hit by the ugly stick, but I'm not exactly a matinee idol."
