It's official: Jesse Eisenberg will play Facebook founder Mark Zuckerberg in "The Social Network," a film based on the creation of the social networking site. But he's not the only rumored name now confirmed to be in the film. Variety reports that Justin Timberlake will also star in the flick alongside Eisenberg.

Timberlake will play Napster co-founder Sean Parker, who became Facebook's founding president. Andrew Garfield has been cast as Eduardo Saverin, the Facebook co-founder who had a falling out with Zuckerberg as the site became a financial success. The crew, along with director David Fincher, will begin filming next month in Boston before moving production to Los Angeles.

One of the film's executive producers, [article id="1616710"]Kevin Spacey, spoke to MTV News[/article] recently about the flick, speculating that it would begin filming before the end of this year, although at that time the details, including who would be directing and starring in the movie, had yet to be worked out.

Spacey did note that he was "enormously excited" about the film. "Great story for people that don't really know how it happened," he said. "Very filmic, very modern, very cool."

Meanwhile, even as late as last week, Eisenberg wouldn't confirm to MTV News that he was tackling the Zuckerberg role. Instead he opted to say only that he was still rumored to be attached to the film, which was penned by "West Wing" creator Aaron Sorkin. At the junket for "Zombieland," he said, "They are rumors. That is true."
