Nine is a 2009 romantic musical drama film directed and co-produced by Rob Marshall from a screenplay by Michael Tolkin and Anthony Minghella, based on the stage musical of the same name, which in turn is based on the 1963 film 8½. In addition to songs from the stage musical, all written by Maury Yeston, the film has three original songs, also written by Yeston. The ensemble cast consists of Daniel Day-Lewis, Marion Cotillard, Penélope Cruz, Judi Dench, Fergie, Kate Hudson, Nicole Kidman, and Sophia Loren.

Nine premiered at the Dubai International Film Festival on December 9, 2009, and had a limited release in New York City and Los Angeles on December 18, with a wide release in the United States on December 25, by The Weinstein Company. Though the film received mixed reviews from critics and was a box-office bomb, the cast and especially Marion Cotillard's performance was praised. Nine was nominated for four Academy Awards: Best Supporting Actress (Penélope Cruz), Best Art Direction (John Myhre and Gordon Sim), Best Costume Design (Colleen Atwood), and Best Original Song ("Take It All").
