Margot Robbie's 'Barbie' body double says she 'barely' knows what the movie is about despite being on set

• Margot Robbie's "Barbie" body double said that she doesn't know the plot of the film.
• Emma Eastwood said that she worked on the set of the movie for two weeks.

Margot Robbie's "Barbie" body double said that the exact plot of the highly anticipated film was kept secret from her while she was on set.

In a new interview with The New York Times, Emma Eastwood, 26, said that this was her first experience as a body double after she applied to play an extra in the movie and was rejected.

Eastwood added that though she was on set for two weeks, she still "barely" knows what the movie is about.

"They did a very good job of keeping the plot hidden," said the actor.

Eastwood added: "They didn't give me any details of what we would be doing. There were a couple times they said the whole cast would be there and it would be an important day, but they never actually gave me any details of what we would be doing until I was on set."

Eastwood said that she was initially hired as a hand double for Robbie but ended up taking on bigger scenes.

However, the actor told the Times that she wasn't given context for any of her scenes and just had to do what she was asked to.

In one scene, which features briefly in the movie's trailer, Eastwood said she had to walk up a set of stairs while acting as if her feet hurt.

In another scene, Eastwood said that she had to lie on the ground facedown for an hour. She was on the ground so long that her makeup smeared on the floor.

"When I got up, I literally felt drunk," she said. "I have no idea what that scene was about."

Eastwood said that she was often mistaken for "Barbie" star, Robbie, on set, and that even Robbie got confused between her and her double when watching back footage.

"Barbie," starring Robbie, Ryan Gosling, and Will Ferrell, is in theaters on July 21.
