The Before and After "Black Swan" Special Effects Video is Stunning

Take a moment to watch the above VFX Breakdown video that reveals the incredible layers of special effects that are used in Black Swan. It boggles the mind how much an image can be altered and shaped. The amazing visual effects (vfx) artists are the frosting on the cake that is Matthew Libatiques's dynamic cinematography. Gorgeous performance by Natalie Portman and some great dancing in the really difficult scenes by her dance double, Sarah Lane.

PS - There is a controversy over who did most of the on-camera dancing - Portman or Lane.
