Black Swan (2010)

Nina (Natalie Portman) is a dancer who becomes increasingly engulfed in the high-pressure demands of world-class ballet. The stress being too much, she spirals into psychosis, and the line between Nina and the role she is meant to play becomes blurred. Black Swan, directed by Darren Aronofsky, is an unnerving exploration of innocence, beauty and the all-consuming (and sometimes deadly) drive for perfection.
