Black swan (spoiler warning)

When my wife asked me out to a movie on her birthday (it should have been the other way around!) I was reluctant because, from what she said, the movie seemed like a girl's manga story in which two ballerinas compete for a lead role.
It was not. Not at all. It was, how can I say, psycho-thriller with a bit of erotic flavor set in a ballet company in New York. I enjoyed it a lot.
----------- (Spoiler warning)-------
Nina is a beautiful, hard working, talented ballerina. Raised by strict and difficult mother, she is still an unmatured good girl inside, obedient to mother, having internalized her(mother's) broken dream to be something in the ballet world. In fact, her mother gave up her own ballet career on conceiving a baby (Nina) of a cold-blooded big shot or other and has been channeling her anger and regret into Nina.
Under mother's suffocating expectations, she is sexually naive, with a kind of innocence that only a person who is not allowed to be skeptical has, which the ballet company's art director Tom(if I remember correctly) thinks the best fit for the white swan role(Princess Odette) of his new modern interpretation of the classic "Swan Lake". But here arises a dilemma. Her innocence is nothing more than a hindrance if she has to play the role of black swan Odile, the dark side of the white swan. The black swan must be seductive, provocative and sexually liberated, which she has suppressed unconsciously all her life deep inside her but her rival has profusely.
Her internalized ambition for winning the lead role, Tom's demand for the black swan, his irresistible manliness, her hidden sexual desire, and her rival Lily, all combined into a madness. Her already fragile mind is breaking down and the line between hallucination and reality blurs. The drama turns into a horror to an extent of beauty.
I'm also impressed with camerawork. In dancing parts a camera swirls around her, flowing along with her movement. I felt as if I were flowing with her. It was a great work with, probably, a hand-held-camera.

On our way home, she told me that Portman (Nina) was that small girl who starred in "Leon the Professional" with Jean Reno. I vaguely remember her but still failed to connect the girl to the matured woman. What's even more amazing is she is not a professional ballerina if she took a lesson in her childhood. I can hardly believe if she did it without a "dance double". Her dancing looked really professional, contrasting with rather amateurish one by her rival Lily.
We stopped in a Chinese restaurant and celebrated her ???th birthday with 3600yen worth of dishes including beer. "Such small eaters we've got.", we laughed.
