On a fall night in 2003, Harvard undergrad and computer programming genius Mark Zuckerberg sits down at his computer and heatedly begins working on a new idea. In a fury of blogging and programming, what begins in his dorm room soon becomes a global social network and a revolution in communication. A mere six years and 500 million friends later, Mark Zuckerberg is the youngest billionaire in history... but for this entrepreneur, success leads to both personal and legal complications.

Every age has its visionaries who leave, in the wake of their genius, a changed world - but rarely without a battle over exactly what happened and who was there at the moment of creation. The Social Network explores the moment at which Facebook was invented -- through the warring perspectives of the super-smart young men who each claimed to be there at its inception. The film moves from the halls of Harvard to the cubicles of Palo Alto to capture the heady early days of a culture-changing phenomenon in the making -- and the way it both pulled a group of young revolutionaries together and then split them apart. In the midst of the chaos are Mark Zuckerberg (Jesse Eisenberg), the brilliant Harvard student who conceived a website; Eduardo Saverin (Andrew Garfield), once Zuckerberg's close friend, who provided the seed money for the fledgling company; Napster founder Sean Parker (Justin Timberlake) who brought Facebook to Silicon Valley's venture capitalists; and the Winklevoss twins (Armie Hammer and Josh Pence), the Harvard classmates who asserted that Zuckerberg stole their idea and then sued him for ownership of it. Each has his own narrative, his own version of the Facebook story in this multi-level portrait of 21st Century success - both the youthful fantasy of it and its finite realities as well. Written by Columbia Pictures
