Uma Thurman has joined Nymphomaniac, Lars von Trier’s two-part porno drama with non-simulated — but body-double- and visual-effects-aided — sex scenes. (The film will be released in hardcore and non-hardcore versions.) It’s currently unclear what role she’ll play and just how the towering actress will be able to have non-comical-looking intercourse with her diminutive male co-stars, Shia LaBeouf, Jamie Bell, and Christian Slater.
