The full trailer for 'The Social Network' (aka "that Facebook movie") has finally hit, following the release of several teasers ("You don't get 500 million friends without making a few enemies,") that kept the Internet abuzz. The film, based on Ben Mezrich's 2009 book 'The Accidental Billionaires: The Founding of Facebook, A Tale of Sex, Money, Genius, and Betrayal,' stars Jesse Eisenberg as Facebook co-creator Mark Zuckerberg and Justin Timberlake as Napster co-founder Sean Parker.
