Nymphomaniac (stylised as NYMPH()MANIAC onscreen and in advertising) is a 2013 European two-part art film written and directed by Lars von Trier. The film stars Charlotte Gainsbourg, Stellan Skarsgård, Stacy Martin, Shia LaBeouf, Christian Slater, Jamie Bell, Uma Thurman, Willem Dafoe and Connie Nielsen. The film was originally supposed to be only one complete entry; but, because of its multiple hour length, von Trier made the decision to split the project into two separate films. Nymphomaniac was an international co-production of United Kingdom, Denmark, Belgium, France, and Germany.
The world premiere of the uncut Volume I occurred on 16 February 2014 at the 64th Berlin International Film Festival, while the uncut Volume II premiered at the 71st Venice International Film Festival. The world premiere of the Director's Cut took place in Copenhagen on 10 September 2014. It was nominated for the 2014 Nordic Council Film Prize.
Nymphomaniac is the third and final installment in von Trier's unofficially titled Depression Trilogy, having been preceded by Antichrist and Melancholia.
