Margot Robbie's body double in Barbie says she had no idea what the hotly anticipated film was about. Barbie marks Emma Eastwood's first gig as a body double after she applied to be an extra but got turned down. She was then hired to be Robbie's hand double but later took on more prominent scenes in the film. In a recent interview with The New York Times, Eastwood candidly shared that she didn't quite know the concept of Barbie. "They did a very good job of keeping the plot hidden," Eastwood said, adding that she wasn't given "any details" about what they would be doing.

In one scene, Eastwood said she was required to lie on the ground for an hour. "When I got up, I literally felt drunk," she told the publication. "I have no idea what that scene was about." Another scene saw her walk up a flight of stairs as though her feet hurt. Eastwood finally lifted the lid on her recent endeavour in a Twitter post, where she told followers she can now publicly reveal she worked as Robbie's doube. "Had the best experience of my life and will absolutely never shut up about it," she wrote. Greta Gerwig's Barbie, featuring Margot Robbie, Ryan Gosling, Kate McKinnon, Will Ferrell, Micheal Cera and Issa Rae, is set to hit cinemas on 21 July. Have your say in our news democracy.
