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. The film features an ensemble cast consisting of Daniel Day-Lewis, Marion Cotillard, Penélope Cruz, Judi Dench, Fergie, Kate Hudson, Nicole Kidman, and Sophia Loren.
The film 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. Although the film received mixed reviews from critics, the cast and especially Marion Cotillard's performance were 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").
In a 2018 interview with The New Yorker, Rob Marshall revealed that he believes the Weinstein Company failed to market the film properly as it was a trickier sell than Chicago and should have started in festivals and smaller venues. He also said, "I did feel somewhat compromised working on it. Everything on the screen wasn't fully my perfect version of it."
The film was released on DVD and Blu-ray on May 4, 2010. The DVD featured an audio commentary by director Rob Marshall and producer John DeLuca, 8 featurettes, and 3 music videos. The Blu-ray Disc included all the DVD extras, including another featurette and a Screen Actors Guild Q&A.
Nine received generally mixed reviews, although the performances of the cast were praised by critics. As of December 2023, the film holds a 39% approval rating on Rotten Tomatoes, with an average rating of 5.2/10. The critical consensus reads, "Nine is a visually stunning and well-acted musical, but it's also overly ambitious and emotionally distant."
