Facebook has somewhere in the neighbourhood of half a billion users, so it's hardly surprising that the "Facebook movie" has been one of the most buzzed-about projects in Hollywood. Then again, basing an entire film on a web site -- even one as epochal as Facebook -- is hardly a guarantee of artistic and/or box-office success.

But the story behind the social networking site and its phenomenal rise has plenty of human drama, as evidenced in Ben Mezrich's 2009 book, The Accidental Billionaires: The Founding Of Facebook, A Tale of Sex, Money, Genius, and Betrayal.

Entitled The Social Network, the picture stars the always-engaging Jesse Eisenberg as FB honcho Mark Zuckerberg, who created the first iteration of Facebook while at Harvard in 2003. (The pic co-stars Justin Timberlake as one of Zuckerberg's collaborators.) Slated for an October release, the movie is written by Aaron Sorkin (The West Wing) and helmed by David Fincher, the auteur behind indelible films like from Seven to Fight Club to the haunting and underrated Zodiac. (Fincher also directed The Curious Case of Benjamin Button, which got copious love from the Academy, but which I found to be an utter grind.)

The trailer for The Social Network (see above) was released last week, and while it reveals nothing of Fincher's visual brilliance, it makes a compelling case for this as a serious, downright suspenseful drama. Is Zuckerberg truly as wicked and ruthless as the trailer insinuates? Who knows. And since this isn't purporting to be a documentary, who cares?
