The Accidental Billionaires: The Founding of Facebook, a Tale of Sex, Money, Genius, and Betrayal is a 2009 book by Ben Mezrich about the founding of Facebook, adapted by Aaron Sorkin for the 2010 film The Social Network. Co-founder Eduardo Saverin served as Mezrich's main consultant, although he declined to speak with him while the book was being researched. After Zuckerberg and Saverin settled their lawsuit, Saverin broke off contact with the author. Source: Wikipedia (en)
