Black Swan is a 2010 American psychological thriller-horror film directed by Darren Aronofsky and starring Natalie Portman, Vincent Cassel, Mila Kunis and Winona Ryder. The plot revolves around a production of Tchaikovsky's Swan Lake ballet by a prestigious New York City company. The production requires a ballerina to play the innocent and fragile White Swan, for which the committed dancer Nina (Portman) is a perfect fit, as well as the dark and sensual Black Swan, which are qualities better embodied by the new arrival Lily (Kunis). Nina is overwhelmed by a feeling of immense pressure when she finds herself competing for the part, causing her to lose her tenuous grip on reality and descend into a living nightmare. Wikipedia

I got it from Susie in the office. Look, I just feel really shitty about what I did and I just really want to make it up to you, so how about I take you out to dinner? Nina: I don't think... Lily: (interrupts) Ok, that's fine! What about drinks? Erica: Sweetie, you need to rest. Lily: (chuckles) Jesus! Nina: Wait.
