Nine is a 2009 musical-romantic film directed and produced by Rob Marshall. The screenplay, by Michael Tolkin and Anthony Minghella, is based on Arthur Kopit's book for the 1982 Tony Award-winning musical of the same name, which was itself suggested by Federico Fellini's semi-autobiographical film 8½. Maury Yeston composed the music and wrote the lyrics for the songs.
The film premiered in London and was released in the U.S. on December 18, 2009, in New York City and Los Angeles, with a wide release on December 25, 2009.

The principal cast consists of Academy Award winners Daniel Day-Lewis, Judi Dench, Nicole Kidman, Marion Cotillard, Penelope Cruz, Sophia Loren, Academy Award nominee and Golden Globe winner Kate Hudson, and Grammy Award winner Fergie. The film was nominated for four Academy Awards: Best Supporting Actress (Penelope Cruz), Best Art Direction (John Myhre (AD), Gordon Sim (SD)), Best Costume Design (Colleen Atwood) and Best Original Song ("Take It All" Music and Lyrics by Maury Yeston).

Approaching the age of fifty, film director Guido Contini (Daniel Day-Lewis) is facing a midlife crisis that is stifling his creativity and leading him into a variety of complicated romantic involvements. As he struggles to write the script for his latest film, Italia, he's forced to balance the numerous formative women in his life, including his wife, Luisa (Marion Cotillard); his mistress, Carla Albanese (Penelope Cruz); his film star muse, Claudia Jenssen (Nicole Kidman); his confidante and costume designer, Lilli La Fleur (Judi Dench); an American fashion journalist, Stephanie (Kate Hudson); a prostitute from his youth, Saraghina (Fergie); and the spirit of his deceased mother, Mamma (Sophia Loren).

Throughout the film, it is slowly revealed that Guido has been traumatized by his strict Catholic childhood, and it is implied he was beaten in boarding school. In present-day, he frequently has visions of his mother, and their love for each other. Guido has not written a word for Italia, although the press, the public, and his crew believe it is complete. Things are further complicated when Guido gets away to a spa retreat, whereupon Carla follows him and they secretly lead a life of love in the musty train station town. Soon, Luisa discovers truths, Claudia admits details, Lilli listens, Saraghina haunts, and Stephanie attempts to woo Guido with her charm.
