After Darren Aronofsky’s massive mainstream success, The Wrestler, we can imagine some of his Pi-era fanboys (not to mention the folks that actually enjoyed The Fountain) worried he’d lost his edge. The trailer for Black Swan , which comes out December 1st, should set their minds at ease. This thriller, set in the competitive world of the New York City Ballet, stars Natalie Portman as a talented but perennially overlooked dancer and Mila Kunis — who, despite her tiresome That ’70s Show character, can actually act — as her possibly imaginary nemesis/Persona-style existential double. Watch the clip, which features a mysterious back wound, a girl-on-girl makeout, a Portman meltdown, and some seriously intense editing, and tell us what you think after the jump.
