Oh Yes! Keira Knightley Copies When Harry Met Sally Orgasm Scene

Keira Knightley has shown off her saucy side in a cheeky short film celebrating the achievements of British talent in the run-up to this year's Oscars.

The 29-year-old star recreates Meg Ryan's famous fake orgasm scene from When Harry Met Sally, moaning increasingly loudly and banging on the table as she gets carried away with her role.

And Dame Judi Dench plays the part of the fellow diner who deadpans to a waiter: "I'll have what she's having."

The hilarious scene is part of a set of three shorts directed by photographer Jason Bell for Vanity Fair in the style of a vintage newsreel - with some of Britain's top talent taking on iconic moments from movie history.

Tom Hiddleston and Felicity Jones are seen as Bonnie And Clyde, while Benedict Cumberbatch becomes Mr Darcy and other stars involved include Jamie Dornan, Sienna Miller, Sam Claflin, Natalie Dormer, Emily Blunt, Gugu Mbatha-Raw, Damian Lewis and James Corden.

If you don't have time to watch all three bits, head straight for the third to check out Keira's bit!
