Enemy on Blu-ray

Jake Gyllenhaal stars as Adam Bell, a glum, disheveled history professor who seems disinterested even in his beautiful girlfriend Mary (Melanie Laurent). Watching a movie on the recommendation of a colleague, Adam spots his double, a bit-part actor named Anthony St. Clair, and decides to track him down. The identical men meet and their lives become bizarrely and irrevocably intertwined.
