Stacy Martin and Shia LaBeouf don't hold back in ''Nymphomaniac: Volume 1''; see others who've disrobed for a role. (Hey, people! The human body is nothing to snicker at! Okay, maybe sometimes...)

As their suggestive promo posters made clear, Lars Von Trier's two-volume exploration of an insatiable woman (played by Martin at a young age in flashback scenes, Charlotte Gainsbourg when character is at her current age) includes graphic sex scenes, with LaBeouf playing her first love(r). There's nudity to spare throughout the film, which includes costars such as Uma Thurman, Willem Dafoe, Christian Slater, and Connie Nielsen. To figure out which of those performers get full-frontal, you'll have to see the film (though EW's Chris Nashawaty wouldn't necessarily recommend it.
