Little truth has been spilled about Lars von Trier's upcoming film Nymphomaniac, and while many who work on the film would like to keep it that way, its producer Louise Vesth opened up about some of the new techniques the Danish director will be implementing in the sex scenes.

When actor Shia LaBeouf went around claiming that he'd be having real sex on camera, he was only partially correct. Instead, von Trier will film the sex scene twice: once with the actors and again with their doubles. In post-production, the doubles' nether regions will be superimposed onto the actors', making it appear as though they were truly getting physical.

“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 the below the waist it will be the doubles," Vesth explained.

The complicated post-production work cost the film an unveiling at Cannes, but it is expected to hit theaters this December.
