Darren Aronofsky shows the dual nature of life as portrayed by the black swan in Tchaikovsky's Swan Lake Ballet. He suggests that the search for perfection may not always be healthy for people. But, it has resulted in an almost perfect film where Natalie Portman is great and has earned the best actress award in 2011. She is well supported by Mila Kunis, Barbara Hershey, Vincent Cassel and Winona Ryder. The background score of Swan Lake by Tchaikovsky is magical and surreal.
