So it turns out Shia LaBeouf won't be using his penis in the new Lars Von Trier movie 

Proving that even the guy who directed Antichrist has limits to what he's willing to subject moviegoers to, one of the producers of Lars Von Trier's upcoming, two-part Nymphomaniac told The Hollywood Reporter yesterday that Shia LaBeouf will not, as previously reported, be giving his manhood an onscreen workout. Okay, so those weren't the exact words of producer Louise Vesth, who instead explained that while the sex in the film will be real, it will be performed by body doubles, and digitally melded with the simulated bump-and-grind of the name actors (who also include Uma Thurman, Stellan Skarsgard, Charlotte Gainsbourg, and the very sexy Udo Kier). “So above the waist it will be the star and the below the waist it will be the doubles," she added. Bummed LaBeouf fans should express their disappointment with the appropriate, customary expression of disapproval.
