Last week it was revealed that Shia LaBeouf, who recently stripped all the way down to his transformer in a Sigur Rós video , will join Charlotte Gainsbourg and Stellan Skarsgård in director Lars von Trier’s Nymphomaniac , a kind of art-porn follow-up to his Antichrist. In the new thriller, which begins filming this week, Gainsbourg tells her “erotic journey from birth to the age of 50.”

Now comes word that English actor Jamie Bell (Billy Elliot, The Adventures of Tintin) and Danish actress Connie Nielsen (Gladiator) have also joined the cast. It’s not known what their roles will be, but as it’s been reported that the sex scenes will be real (this is not a first for a non-porn film, surprisingly), chances are pretty good that they’ll be using acting muscles they never knew existed. In cases where a sex act is illegal, the picture will be blurred. So, phew!
