Even before his life starts getting weird, Adam Bell is messed up. A schlumpy Toronto history professor who drones on about totalitarian societies, Adam walks with a crabbed, defeated gait; his lovemaking with girlfriend Mary (Mélanie Laurent) is as perfunctory as his lecturing style. Maybe this explains why he comes down with a severe case of heebie-jeebies upon discovering his exact physical double in the form of a bit player in a minor movie. At least something is happening in Adam’s life. The actor’s name is Anthony Clair, he lives in town, and he’s a much more aggressive guy than Adam. They both have beards, and they are both played by Jake Gyllenhaal.
Enemy gives Gyllenhaal a dramatic workout, and he is up to the challenge.
