The Social Network (2010)

Mark Zuckerberg (Jessie Eisenberg) is a Harvard college student who's a whiz with computers.  Zuckerberg is also socially inept.  He says some unflattering things to Erica (Rooney Mara), his girlfriend, and she drops him.  His response?  He insults Erica on his blog. Oh, and he creates a web site that rates the women of Harvard as being hot or not hot.   The second thing shuts down Harvard's computer system, and Zuckerberg finds himself in trouble with the school.

A pair of wealthy twins with the last name of Winklevoss (Armie Hammer) see the genius in Zuckerberg, and they deal him in to start a social networking site for Harvard students.  Zuckerberg puts together a site alright, but he names himself and friend Eduardo (Andrew Garfield) as co-creators.  Later, Zuckerberg brings in the creator of Napster, Sean Parker (Justin Timberlake), as a partner, despite warnings from Eduardo that it may not be a good idea.  The story of how Facebook was started is framed by a deposition session where it's revealed that Zuckerberg is being sued by Eduardo and the Winklevoss twins over issues of who really had the idea for the web site and who was owed what. 

Zuckerberg is not exactly shown to be a nice guy, but it's hard to say that there was malicious intent behind his business dealings.  At best, the Internet billionaire is a guy who was so intently focused on an idea that he forgot that humans were just as important in the process as the computer code he was writing. 

Justin Timberlake, formerly of the group N'Sync, and now a solo singer, is actually quite good here as a guy who takes interest in Facebook and talks his way in.  Rashida Jones (daughter of musician/producer Quincy Jones) appears as an attorney who appears to be sympathetic towards Zuckerberg.  Aaron Sorkin ("The West Wing", A Few Good Men) who wrote the screenplay, has a cameo as an ad executive.
