When you see Keira Knightley pulling all sorts of crazy faces in her new movie A Dangerous Method, just remember that she's not being caught up in the heat of passion- every grimace, smirk, and over-dramatic eye roll is the result of careful preparation.

Keira claims she went slightly Method for her role as psychiatric patient and BDSM fanatic Sabrina Spielrein, not only perfecting her O-face, but then putting on a free show for director David Cronenberg on Skype:

"It was a huge part of what Sabina was doing a lot of the time," Keira told The Sun. "I asked psychoanalysts about it and they said, 'sex and anything like that is trying to release pent-up emotion."

"So I worked with that and sat in my bathroom and pulled faces at myself" (Oh, so that's what you call it, eh?) "for two days. Then I got on Skype with David and went 'Ive come up with this' or 'I've come up with that' and he went, 'that one!'"

Two days!? She's lucky she didn't give herself carpal tunnel!
