In 1999, Björk was asked to write and produce the musical score for the film "Dancer in the Dark", a musical drama about an immigrant named Selma who is struggling to pay for an operation to prevent her son from going blind. Director Lars von Trier eventually asked her to consider playing the role of Selma, convincing her that the only true way to capture the character of Selma was to have the composer of the music play the character. Eventually, she accepted. Filming began in early 1999, and the film debuted in 2000 at the 53rd Cannes Film Festival. The film received the Palme d'Or, and Björk received the Best Actress Award for her role. It was reported that the shoot was so physically and emotionally tiring that she vowed never to act again. Björk later stated that she always wanted to do one musical in her life, and "Dancer in the Dark" was the one. The soundtrack Björk created for the film was released with the title "Selmasongs". The album features a duet with Thom Yorke of Radiohead titled "I've Seen It All", which was nominated for an Academy Award for Best Original Song and was performed at the 2001 Oscars (without Yorke), while Björk was wearing her celebrated swan dress.
