Black Swan

Natalie Portman gives the performance of a lifetime as Nina, a stunningly talented but dangerously unstable ballerina on the verge of stardom. Pushed to breaking point by her driven artistic director (Vincent Cassel) and the threat posed by a seductive rival dancer (Mila Kunis), Nina's tenuous grip on reality starts to slip away. As the pressure builds, Nina's all-consuming obsessions spin out of control, plunging her into a waking nightmare that will threaten not only her sanity, but her life.
