Justin Timberlake joins 'The Social Network' cast

Justin Timberlake and Jesse Eisenberg have reportedly joined the cast of "The Social Network," a flick based on local author Ben Mezrich's tell-all book about the founding of Facebook in a Harvard dorm, with production slotted to kick off in Cambridge on Monday, Oct. 19.

Crews plan to film at the Thirsty Scholar Pub located at 70 Beacon St. in Somerville on Wednesday, Oct. 21 and Thursday, Oct. 22.

Timberlake will play Sean Parker, the Napster co-founder who became the founding president of Facebook while Eisenberg has been cast as Mark Zuckerberg. Andrew Garfield stars as Eduardo Saverin, a former founder who had a fallout with Zuckerberg.

As previously reported in Loaded Gun Boston, crews are actively looking for locations in Cambridge and Boston armed with a script crafted by Aaron Sorkin, the writer for such flicks as "Charlie Wilson's War" and "A Few Good Men." While several scenes will be shot in Cambridge, a part of the movie may be filmed in California.

Kevin Spacey, who in 2007 filmed the made-in-Boston flick "21" which was also inspired by one of Mezrich's non-fiction works called "Bringing Down The House," is producing alongside Scott Rudin and Dana Brunetti.

David Fincher, known for highly stylized work with films like "The Curious Case of Benjamin Button" and "Fight Club," is in advanced negotiations to direct.

The script follows founder Zuckerberg getting dumped at a Boston-area bar and ends with him adding his former girlfriend to his friend list on his multibillion-dollar social networking site. The story is based on Mezrich's latest book, "The Accidental Billionaires: The Founding of Facebook. A Tale of Sex, Money, Genius and Betrayal."

Zuckerberg launched Facebook in Cambridge of 2004 before he moved to a house in Palo Alto, California and opened his first office on the Left Coast in the summer. As Facebook lore suggests, he planned to return to Harvard in the fall of '04, but never did.

Sorkin's 162-page script includes some supposed behind-the-scenes banter with ConnectU founders Cameron Winklevoss, Tyler Winklevoss and Divya Narendrera after filing a lawsuit in 2004 alledging the unauthorized use of ConnectU's source code.
