Last week Yahoo! Movies released the first full-length trailer for The Social Network, written by Aaron Sorkin and directed by David Fincher.

The film is an adaptation of the book The Accidental Billionaires: The Founding of Facebook A Tale of Sex, Money, Genius and Betrayal by Ben Mezrich. The Social Network is about the early days of Facebook, and addresses some of the issues facing the company today. The film also draws parallels from the fictionalized account of its start in The Accidental Billionaires.

Mezrich recreates the foundation and rise of the Facebook phenomenon, although loosely connected to real events, which tells the story of two Harvard undergrads who revolutionized how we connect to others. The road to the initial Facebook concept was paved with betrayal, vast amounts of cash and two friends who wanted nothing more than to be cool. It’s juicy, fast-paced and if the book is any indication, the film is going to be a must see!

What do you think of the trailer? Are you going to see the film in theaters this October?
