Shia LaBeouf wanted to wear a penis cam for Nymphomaniac.

The 27-year-old actor - who plays Jerome in the risque drama about a woman's erotic journey from birth to the age of 50 - asked director Lars Von Trier if he could put a filming device on his manhood while shooting the sex scenes to give viewers the "full experience."

"Shia had wanted Von Trier to put a camera on his penis while filming, so that audiences could have the full experience," a source told The New York Post.

However, the cheeky close-up would have been too much for the audience and his co-stars, so the idea was scrapped.

Meanwhile, it is believed the star's recent antics - including showing up to the film's premiere wearing a paper bag over his head and pulling his own tooth out to get into his role for Fury - could be costing him potential parts in upcoming movies. However, insiders insist his erratic behaviour is all part of a "performance art" hoax. "Everyone who knows Shia is in on the joke. It's all part of an act," the source said.
