Facebook has slammed The Social Network as a work of "fiction" that lies to be entertaining. Yet a company spokesman ended up inadvertently writing a climactic line of dialog that ties the Facebook movie together. Whoops.

The forthcoming Facebook movie exists thanks to an embittered co-founder who blabbed about the company's origins. Instant messages from CEO Mark Zuckerberg, below, describe the "dirty tricks" that made the co-founder so angry—and so indiscreet.

New pictures from the Facebook movie's set have none other than script-originating novelist Ben Mezrich uncertain how he feels. With clips from corresponding portions of the script, we decipher Mark Zuckerberg's sleepy-time befuddlement and Timberlake's alpha male "fuck you."

It appears Aaron Sorkin has confirmed many of the casting choices for his upcoming Facebook movie. If only Silicon Valley were this good looking. There's someone from Gossip Girl, Melanie Griffith's daughter — even a very built male model.

Scriptshadow, which obtained the first leaked script for Facebook movie The Social Network, now claims to have casting choices, including Justin Timberlake as Napster's Sean Parker. News In Film created this handy graphic.

Aaron Sorkin told the website MakingOf that he's never agreed to a project so fast as when he signe on to adapt Ben Mezrich's Facebook book. Sorkin still doesn't know what he was thinking.

It's being turned into a movie by Aaron Sorkin, but Ben Mezrich's book about the creation of Facebook is apparently as badly written as a typical status update on Facebook. Janet Maslin's New York Times review is unsparing.

Ben Mezrich's forthcoming Facebook exposé was sold to film producers before it was even written. The Hollywood influence helps explain why the book answers such pressing questions as, "Who might the co-founders have conceivably boned, and where?"

Columbia Pictures is close to securing a director for its Facebook movie: David Fincher, of Fight Club fame, is reportedly in advanced talks. He'll be expected to move fast, before the market for a movie about the social network evaporates.

Facebook's creation myth has left the building, or so we hear: Fortune is said to be readying an excerpt of Ben Mezrich's tell-all book and movie about the social network. And another publication is, naturally, trying to ruin the scoop.

After years of freezing out cofounder Eduardo Saverin over a dispute about money, Facebook CEO Mark Zuckerberg has deigned to recognize his former Harvard buddy. Why now? Perhaps to derail a forthcoming Facebook tell-all?

Yes, there's going to be a book about Facebook's creation, adapted for film by Aaron Sorkin, bestselling author Ben Mezrich confirmed. But it won't have lots of sex and cooked Koala, per a Gawker report.

The author of Bringing Down The House has signed a million-dollar-plus book deal for his memoir about Mark Zuckerberg and the other Facebook founders, according to a tip to Gawker. In the proposal, author Ben Mezrich claims that Zuckerberg and his friend Eduardo Saverin started Facebook to get into a secret society and, of course, to get laid. The book may not be the most rigorously factual account, as Mezrich's Bringing Down The House (the basis for the Kevin Spacey film 21) was debunked by the Boston Globe as "not a work of 'nonfiction' in any meaningful sense of the word." Also, our tipster claims Mezrich's only source was Saverin, whom Zuckerberg is now suing. Here are the juiciest (and previously unreported) details from the proposal.
