Black Swan is a 2010 American psychological thriller directed by Darren Aronofsky. The film stars Natalie Portman and Mila Kunis as ballet dancers in a New York City production of Swan Lake. The production requires a ballerina to play both the innocent White Swan and the sensual Black Swan. Nina (Portman) fits for the White Swan, Lily (Kunis) fits for the Black Swan, and the two compete for the parts. Aronofsky and Portman first discussed the project in 2000, and after a brief attachment to Universal Pictures, Black Swan was produced in New York City in 2009 under Fox Searchlight Pictures. Notable figures from the ballet world helped with film production to shape the ballet presentation. The film is set to premiere as the opening film for the 67th Venice International Film Festival in September 2010. The film will have a limited release on December 1, 2010.
