Distributor U.S. Release
Jesse Eisenberg plays Simon, a timid, isolated man who’s overlooked at work, scorned by his mother, and ignored by the woman of his dreams (Mia Wasikowska). The arrival of a new co-worker, James (also played by Eisenberg), serves to upset the balance. James is both Simon's exact physical double and his opposite - confident, charismatic and good with women. To Simon's horror, James slowly starts taking over his life.
