Jude Law reveals weird on-set ritual

Jude Law told Yahoo! Movies that he freaks out co-stars with bizarre gurning right before the camera rolls.

The British star gave us a glimpse of the ridiculous face he pulls before filming scenes and claims that it "helps to relax the face" before takes.

He said: "The problem is that if you keep doing it people think you have a really bad twitch. It could be quite off-putting but I do it a lot".

See the odd facial expression in the video below:

Law's 'Anna Karenina' co-star Keira Knightley didn't seem too bothered by his antics, and was more irritated by the actor's good looks.

She said: "He looks so good when he takes his make-up off. It's really annoying. We'd all be looking very nice during the day and then take our make-up off and look crap and he'd take his make-up off and look shiny and really handsome.

"I think that would p*** me off".
