First Look:

Black Swan, director Darren Aronofsky's psychological thriller set against the backdrop of the ballet world, isn't due in theaters until December, but the trailer is already heating up the internet

Natalie Portman and Mila Kunis play rival ballerinas vying for the lead in Swan Lake -- Kunis's character clearly interested in making life a living hell for Portman's Nina. And as in many a thriller with two female leads before it, the two actresses also seem to steam up the screen with a lip-lock ... and possibly much more.
