Elizabeth Olsen, the sister of never-nudes Mary-Kate and Ashley Olsen, makes her nude debut as a brainwashed cultist (like one of the Manson Girls) undergoing deprogramming in Martha Marcy May Marlene, which was snatched up by Fox Searchlight at the Sundance film festival.

Finally, everyone who's ever wanted to see a naked Olsen can get the chance to.

“It was incredibly weird to watch it with other people watching it, especially during nude parts,” Olsen explained about seeing her bare body on screen during the film festival.

But it's all for the love of the craft that Elizabeth takes it off and gets down for some semi-graphic sex scenes.

“My dad, when he found out there was nudity in the film, was like, are you sure this is a good idea? Me as a person, I don’t even wear things that show my midriff ever. I’m a very covered-up human being.”

If one Olsen can change, then so can the twins. Look to Karissa Shannon.

Relax, Elizabeth, it's only a booby movie!
