Nina Sayers (Natalie Portman) has finally scored her big break with the New York City Ballet, landing the lead role in Swan Lake. But a new dancer, Lily (Mila Kunis), goes deeper and darker, threatening Nina’s star-making turn. As Nina’s paranoia increases, her obsessions take on a life of their own and she becomes less reliable as the movie’s protagonist. This is director Darren Aronofsky’s most psychologically unhinged film, and it’s one of the most twisted thrillers of the decade. It blurs reality as much as Inception, with an ending that will spark just as much debate. There are moments in Black Swan that are as compassionate as Aronofsky’s The Wrestler, as destructive as his Requiem for a Dream, and as totally mindfucking as Pi. It’s also his most fluid movie and one of the year’s best a masterful psychological thriller that pulls you along to its dark, devastating end.
