Maybe this pic of Aaron Eckhart has been photoshopped to be blurry on one side. Or maybe this is the first pic of Two-Face, rumored to be first seen at the end of the upcoming The Dark Knight, and to be featured in the third Christopher Nolan Batman movie.
Based on how gruesome the Joker looks, I had pretty high expectations for Two-Face: flesh dripping, strand of skin across the mouth, eye socket exposed. So I doubt it's real.
Added: Definitely a fake; it's a photoshopped image from the movie The Core.
