James Sex Scene Hell

James McAvoy secretly hates filming sex scenes.

He’s told Parky: "It's always a nightmare, isn't it?"

"It's never easy and it's always a little bit sweaty and uncomfortable."

The 28-year-old actor – who is currently appearing alongside Keira Knightley in the brilliant movie Atonement – added: "When they call action, if you feel the lady's breast, it's your decision to feel the lady's breast. It's like, this is wrong. You have no parameters."

"We carried on and about 10 seconds later we just said very sheepishly, 'Sorry about that.'"

James clarified: "What was great about Atonement was Joe Wright, the director, was very, very, very on the ball with what he wanted, so when you were doing something it was at his behest."
