It's not porn if it's art, right? Shia Labeouf is officially a Nymphomaniac, and he says that he will do "whatever is asked for" for his upcoming role in maverick filmmaker Lars von Trier's sexually explicit next movie, which requires the Transformers star to do it "for real."

LaBeouf, who was featured in the buff -- full-frontal style -- in a recent Sigur Ros video, told MTV, "[Von Trier is] the most dangerous dude that I've ever showed up for. I'm terrified. I'm so terrified, which is why I have to go. We'll see what happens."

Nymphomaniac is said to follow a woman throughout her sexual life, and it's reported that the director of such films as Breaking the Waves, Dancer in the Dark and Melancholia plans to make two versions of his film: One all-out, hardcore version, and one that's less explicit.

"It's going to be a wild movie," said LaBeouf, explaining, "There's a disclaimer at the top of the script that basically says we're doing it for real. Everything that is illegal, we'll shoot in blurred images. Other than that, everything is happening."
