James McAvoy named sex scenes with Keira Knightley “sweaty and uncomfortable.”

Knightley is acting with James in “Atonement” and her scenes are for him a “nightmare.”

He also revealed that : “It’s always a nightmare filming sex scenes, isn’t it? It’s never easy and it’s always a little bit sweaty and uncomfortable,” he says.

Knightley agrees with McAvoy and she has admited that :“Obviously it’s never going to be the most comfortable thing to do, and particularly when your mate is directing you. And you suddenly think, ‘Oh s**t I don’t really want to do this.’ But it became a laugh,” she says.
