Natalie Portman and Mila Kunis play rival ballerinas in Black Swan, but this film isn’t made for little girls.

The dark thriller revolves around a New York ballet company which is staging a performance of Swan Lake. Portman’s character is picked to dance the lead role, but the arrival of a new dancer (Kunis) creates new tension and competition.

Kunis stretches her villain chops in the flick, which will be released December 1.
