It isn't a secret that Darren Aronofsky had originally conceived "Black Swan" as a sister project to "The Wrestler," but never before have we heard the actual process through which the concept developed... until now, that is!

We got their hands on an exclusive behind-the-scenes clip from the "Black Swan" DVD and Blu-ray, currently in stores, where Aronofsky discusses how he came up with the idea of a ballerina who performed in "Swan Lake" and found herself torn apart by a double persona -- and it all started with Aronofsky reading Fyodor Dostoevsky's "The Double: A Petersberg Poem."

"I was reading Dostoevsky's 'The Double' which is about a guy who wakes up and his double's there starting to replace his life, and I was thinking of how to do something with it," Aronofsky said. "I went to see Swan Lake at the ballet and didn't know one dancer played two roles -- a white swan and a black swan -- and it was sort of an ah-ha moment."

From there, the connection seemed easy, and anyone who's seen "Black Swan" can probably see how Aronofsky got from this concept of a man who is destroyed by his double combined with the tragic story of "Swan Lake" to come up with the final product of this film.

"I realized there was the story of a double here, except it was better in its own way because the white swan and the black swan were such beautifully drawn characters," he said. "I felt I could really build on that and turn it into something."
