Eisenberg plays Simon a man who finds he has a doppelganger, someone who looks just like him. Only his double is assuming his identity and doing a better job at being him than he is.
Simon slowly starts going mad when he finds that this double has usurped his tenuous position in the company. He is wildly more confident and successful and better liked by his colleagues.
Real troubles begin when Simon, who is fatally ineffectual, must fight for the affections of the woman of his dreams, played by Wasikowska.
Richard Ayoade directs the film, based on an 1846 absurd comedy novella by Russian literary giant Fyodor Dostoyevsky.
The British comedy, which also stars Wallace Shawn, Noah Taylor, Yasmin Paige and James Fox, debuted at the 2013 Toronto International Film Festival.
