Dancer In The Dark is a 2000 musical psychological tragedy film written and directed by Lars von Trier. It stars Icelandic musician Björk as a factory worker who suffers from a degenerative eye condition and is saving for an operation to prevent her young son from suffering the same fate. Catherine Deneuve, David Morse, Cara Seymour, Peter Stormare, Siobhan Fallon Hogan and Joel Grey also star. The soundtrack for the film, Selmasongs, was written mainly by Björk, but a number of songs featured contributions from Mark Bell and some of the lyrics were written by von Trier and Sjón.
