Each character measures the other on their own and do not scruple to show themselves in full force. You can only add a banal, that the world of ballet – one of the faces of the world as a whole. The entire film is the struggle between them, and Aronofsky masterfully keeps in suspense, does not give off the screen for a second. The fight for the title, a crucial role in the final formulation in which you want to be able to demonstrate both a beginning – and dark, and light to play both games. Nina can only party white swan, no more. For the execution of the party she was not a black swan lack of frivolity, vice, corruption – and the character and temperament and, as a consequence, in the dance. But gradually it occurs a dramatic change, and the former Nina is already difficult to find. If at first it appears to us hateful "sweet girl" a good boy, squeezed, and held down the right, who can not let go of yourself, you will soon start totally amazing transformation – the cries, tears, tantrums and nervous breakdowns, accompanied by persistent delusions on the verge – animating reflection in a mirror, giggling portraits in the wall in my mother's room, the girl in the bathroom, the zombies in the kitchen, fused toes, teething on the blades of black feathers, etc. – just dump the head. In this respect, the game Natalie Portman – above all praise, the range of her acting skills are extremely diverse, it grabs and does not let your attention for a moment.
