Enemy

A man attends an erotic show at an underground club, which culminates with a naked woman on the verge of crushing a live tarantula under her platform high-heel. Adam Bell, a college history professor, lives a quiet, monotonous life in Toronto. He rents a film, Where There's a Will There's a Way, on the recommendation of a colleague, and spots an actor who looks strikingly like himself, briefly, in the film as a bellhop. Searching online, Adam identifies the actor as Anthony Claire, whose stage name is Daniel Saint Claire. Adam rents the other two films in which Anthony has appeared and becomes obsessed with the man, who appears to be his physical twin. Immediately afterwards, Adam searches some boxes in his own house and finds a photo of someone who looks like himself, with a woman's hand over his shoulder. However, part of the photo is torn out, making the woman impossible to identify.
