Margot Robbie and Leonardo DiCaprio in Wolf of Wall Street

Actress Margot Robbie made her mark on Hollywood, when she starred opposite Leonardo DiCaprio in the 2013 Jordan Belfort biopic, The Wolf of Wall Street.

In a recent interview for Vanity Fair, the 26-year-old opened up about the “awkward” sex scenes she filmed for the movie.

“Actually, I hadn’t done a proper sex scene before,” Robbie said in the interview. “I’d done scenes where it’s leading into sex or sex has just finished, but I hadn’t done a start-to-finish sex scene like I did in [Wolf of Wall Street]. That was my first.”

No matter who the co-star, Robbie says that simulating sex in front of “tons of people” is about as comfortable as you think. “There isn’t an option,” she explains. “It’s just like, This is what you need to do — get on with it. The sooner you do it, the sooner you can stop doing it.”

“It’s so awkward,” Robbie said.

Robbie is set to appear in next month’s Suicide Squad, where she portrays the superhero villain Harley Quinn. She also appears in newly released The Legend of Tarzan as Jane Porter, opposite Alexander Skarsgård.
