'Nymphomaniac' racy posters: Did the actors really have sex on screen?

Exactly how far did director Lars Von Trier go with his racy film “Nymphomaniac?”

Newly released posters for the movie show A-List stars like Shia LaBeouf and Uma Thurman naked and in the heat of the moment, but did the actors actually have sex while filming to make the movie?

LaBeouf implied in an interview with MTV, during the film’s production, that the actors we’re definitely going to have sex on screen.

“There's a disclaimer at the top of the script that basically says we're doing it for real,” he told MTV News. “Everything that is illegal, we'll shoot in blurred images. Other than that, everything is happening.”

But according to the Hollywood Reporter, body doubles were used for the actual sex scenes.

“Nymphomaniac”  producer Louise Vesth told the site, "We shot the actors pretending to have sex and then had the body doubles, who really did have sex, and in post we will digital-impose the two. So above the waist it will be the star, and below the waist it will be the doubles."

So did they or didn’t they? Guess we will have to see the film to find out. But that may be a while... No U.S. release date is currently set for “Nymphomaniac.”
