In Enemy, actor Jake Gyllenhaal plays a simple man who discovers his twin while watching a strange film. He then hunts down this doppelgänger, and as you can guess, things do not go as planned. Gyllenhaal plays both the main and his mysterious double.

Enemy will hit US theaters on March 14th, and is currently available on DirecTV.
