Towelroad.com posted a fascinating view of the special effects used in Black Swan. It’s no secret we’re big fans of the movie here at Art Attack, and here’s another reason why. Instead of banal visual effects, the film uses them for intellectual purposes in subtle and haunting ways: The tattoo on Mila Kunis’ back grows during the infamous lesbian scene, and Natalie’s alter-ego torments her in every mirror scene.

In the video, Dan Schreker, visual effects supervisor for the movie, shows us how his team collaborated with the film’s director, Darren Aronofsky, to create these artful tricks of the eye.
