Fox Searchlight have released the brand new international trailer for psychological ballet thriller Black Swan.

Directed by Darren Aronofsky, Black Swan stars Natalie Portman, Mila Kunis, Winona Ryder, Vincent Cassel and Barbara Hershey.

Black Swan has already picked up rave reviews after premiering at the 35th Toronto International Film Festival and recently received four nominations for the 2011 Film Independent Spirit Awards, set to be held on February 26, 2011.

Synopsis: A New York City ballet company is producing Swan Lake, and director Thomas Leroy (Cassel) decides to replace prima ballerina Beth MacIntyre (Ryder) with ballerina Nina (Portman). Nina lives with Erica (Hershey), her overbearing mother and a former ballerina. Nina finds competition in new dancer Lily (Kunis). Swan Lake requires a ballerina who can play the innocent White Swan, which fits Nina, and the sensual Black Swan, which fits Lily. The dancers’ rivalry changes into a bizarre friendship, and Nina begins exploring a dark side of herself.

Black Swan will be released in the UK on January 21, 2011.
