Uma Thurman has joined the cast of 'Nymphomaniac'.
Charlotte stars as self-confessed sex addict Joe, who is rescued by a kind stranger (Stellan) after she is left badly beaten in an alleyway. Joe then recounts her past misadventures and sordid sexual history from birth until the age of 50.
Shia recently admitted the cast have signed up for engaging in real sex scenes on camera, which he was willing to do for the sake of his art.
He said: ''There's a disclaimer at the top of the script that basically says we're doing it for real. Everything that is illegal, we'll shoot in blurred images. Other than that, everything is happening.''
Speaking of the headline-grabbing Danish director, he revealed: ''He's very dangerous. He's the most dangerous dude I've ever showed up for. I'm terrified.''
The film will be available in two versions - hardcore and softcore - when it is released in 2013.
