Playing two versions of himself, Jesse Eisenberg fans get to double their pleasure watching the actor in his new movie, “The Double.” It premieres at the Toronto International Film Festival on Saturday (September 7).

The “Social Network” star portrays a shy man whose life is turned inside out when a would-be doppelganger enters it. Yet this mirror image of himself physically has a far different personality.

Mia Wasikowska co-stars in the movie, which is loosely based on the Fyodor Dostoyevsky novella of the same name.

The first trailer for the film gives viewers a glimpse inside the mind-bending tale, set to a tune by the legendary bluesman Son House, called “Grinnin' in Your Face.”
