Keira Knightley Re-Enacts Meg Ryan’s Famous Orgasm Scene From When Harry Met Sally: Watch!

We'll have what she's having! As part of Jason Bell's British Invasion short film for Vanity Fair, Keira Knightley joined a bevy of other A-list stars from across the pond — including Knightley's Imitation Game costar Benedict Cumberbatch — in re-enacting famous moments in Hollywood history.

Among the highlights? Tom Hiddleston and Felicity Jones doing their best Bonnie and Clyde, Michelle Dockery reciting Lauren Bacall's oft-quoted line from To Have and Have Not, and Game of Thrones star Richard Madden channeling Clark Gable in Gone With the Wind.

The piece de resistance, however, is Knightley's enthusiastic re-enactment of Meg Ryan's famed orgasm scene from the 1989 romantic comedy When Harry Met Sally. Even better? The punch line — "I'll have what she's having" — is delivered by none other than Dame Judi Dench.

Bell told VF he offered multiple options to each star, and that Knightley chose the orgasm scene herself. "I didn't know which bit [Keira] would do," he recalled. "She kind of laughed and said, 'It's the orgasm we've got to do.'"

After that, he explained, it was easy to get everyone else on board. "Once you had Keira Knightley faking an orgasm and Judi Dench saying, 'I'll have what she's having,' it was a pretty easy sell," he shared. "Everyone just said, 'Sure, what do you want me to say?'"
