Gentlemen looking to butter their popcorn while watching Natalie Portman, Mila Kunis, and Kristina Anapau in acclaimed director Darren Aronofsky’s (The Fountain) new supernatural thriller Black Swan are encouraged to employ an elegant pinky-out stroke while doing so. Judging by the film’s trailer, this is going to be a classy affair.

Take a gander, but don’t stare.  It’s rude:

Black Swan stars Portman, Kunis, Anapau, and Winona Ryder as dancers competing to land a role in their company’s production of “Swan Lake.” The film has generated a lot of buzz thanks in part to a reportedly graphic sex scene between Portman and Kunis.

Costars include Sebastian Stan (The Apparition), Barbara Hershey (Riding the Bullet) as Nina’s mother, and Vincent Cassel (The Cross) as the ballet’s director Yevna.

Black Swan will open the Venice International Film Festival on Sept 1.
