Black Swan is a 2010 American psychological horror film directed by Darren Aronofsky. The screenplay was written by Mark Heyman, John McLaughlin, and Andres Heinz, based on an original story by Heinz. The film stars Natalie Portman, Vincent Cassel, Mila Kunis, Barbara Hershey and Winona Ryder. The plot revolves around a production of Tchaikovsky's Swan Lake ballet by a prestigious New York City ballet company. The production requires a ballerina to play the innocent and fragile White Swan, for which the committed dancer Nina (Portman) is a perfect fit, as well as the dark and sensual Black Swan, which are qualities better embodied by the new arrival Lily (Kunis). Nina is overwhelmed by a feeling of immense pressure when she finds herself competing for the part, causing her to lose her tenuous grip on reality and descend into a living nightmare.
Usually described as a psychological horror film, Black Swan can be also interpreted as a metaphor for achieving artistic perfection, with all the psychological and physical challenges one might encounter, i.e. "the film can be perceived as a poetic metaphor for the birth of an artist, that is, as a visual representation of Nina’s psychic odyssey toward achieving artistic perfection and of the price to be paid for it."
Aronofsky conceived the premise by connecting his viewings of a production of Swan Lake with an unrealized screenplay about understudies and the notion of being haunted by a double, similar to the folklore surrounding doppelgängers. Aronofsky cites Fyodor Dostoyevsky's The Double as another inspiration for the film. The director also considered Black Swan a companion piece to his 2008 film The Wrestler, with both films involving demanding performances for different kinds of art. He and Portman first discussed the project in 2000, and after a brief attachment to Universal Studios, Black Swan was produced in New York City in 2009 by Fox Searchlight Pictures. Portman and Kunis trained in ballet for several months prior to filming, and notable figures from the ballet world helped with film production to shape the ballet presentation.
The film premiered as the opening film for the 67th Venice International Film Festival on September 1, 2010. It had a limited release in the United States starting December 3, 2010 and opened in wide release on December 17. Portman's performance and Aronofsky's direction were praised. The film grossed $329 million worldwide. The film received five Academy Award nominations, including for Best Director and Best Picture; Portman won the award for Best Actress for the performance in the film, in addition to many other accolades.
