I can't tell who who or what Hershey will be playing, but I can tell you that Black Swan concerns a ballerina, played by veggie queen Natalie Portman, who has issues with a dancing rival played by Mila Kunis. Various sources indicate that Aronofsky might be going the twisted Fight Club route here...by having Kunis's character exist only in Portman's imagination.
Those of us who hoped The Wrestler marked a turn away from the fanciful and jack-offy for the talented Aronofsky are apparently in for a disappointment. He can make up for it by having Hershey staple something to herself.
