The story of Nina, a ballerina in a New York City ballet company whose life, like all those in her profession, is completely consumed with dance. She lives with her retired ballerina mother Erica who zealously supports her daughter's professional ambition. When artistic director Thomas Leroy decides to replace prima ballerina Beth MacIntyre for the opening production of their new season, Swan Lake, Nina is his first choice.
Black Swan is a 2010 American psychological horror film directed by Darren Aronofsky from a screenplay by Mark Heyman, John McLaughlin, and Andres Heinz, based on a story by Heinz. The film stars Natalie Portman in the lead role, with Vincent Cassel, Mila Kunis, Barbara Hershey, and Winona Ryder in supporting roles. The plot revolves around a production of Tchaikovsky's Swan Lake by the company of New York City Ballet. The production requires a ballerina to play the innocent and fragile White Swan, for which the committed dancer Nina Sayers (Portman) is a perfect fit, as well as the dark and sensual Black Swan, which are qualities better embodied by the new rival Lily (Kunis). Nina is overwhelmed by a feeling of immense pressure when she finds herself competing for the role, causing her to lose her tenuous grip on reality and descend into madness.
