The film stars Charlotte Gainsbourg, Stellan Skarsgård, Stacy Martin, Shia LaBeouf, Christian Slater, Jamie Bell, Uma Thurman, Jean-Marc Barr, Willem Dafoe, Connie Nielsen, and Mia Goth in her debut. Separated as two-part films, the plot follows Joe, a self-diagnosed "nymphomaniac," who recounts her erotic experiences to a bachelor who helps her recover from an assault. The narrative chronicles Joe's promiscuous life from adolescence to adulthood and is split into eight chapters told across two volumes. The film was originally supposed to be only one complete entry, but, because of its length, von Trier made the decision to split the project into two separate films. Nymphomaniac was an international co-production of Denmark, Belgium, France, and Germany.
