Black Swan (2010)

A ballet thriller? Yes! The story is told from Nina's perspective. Nina, the daughter of a ballerina, is now a ballerina herself.  She is thrilled to get the part of the Swan Queen in the upcoming production of Swan Lake.  Her part is actually two - the white swan and the black swan.  She is flawless as the gentle white swan, but lacks the raw passion necessary to be the black swan.  As the stress of training for the two parts wears her out, she begins to have frightening hallucinations. For her, everything is real. It is up to us, the audience, to decide what is real and what is fantasy. Will Nina survive the mental strain of stardom?

Bonus points for special effects here. I am impressed.
