We all love hanging out, "poking" and stalking our friends online, but is it really a compelling topic for a movie?

David Fincher may direct a film about Facebook.

Some people think so. The news broke yesterday that "Seven" and "The Curious Case of Benjamin Button" director David Fincher is in talks to direct a film about Facebook.

Yes, that's right: Facebook.

The film is being produced by Scott Rudin, the brains behind quality fare like Coen Brothers' "No Country for Old Men" (2007) and Stephen Frears' "The Queen," and actor Kevin Spacey and written by Aaron Sorkin.

It will apparently chart the evolution of social networking site Facebook from a inter-collegiate social site started by Harvard sophomore to a global phenomenon with more than 200 million users.

How could a movie on Facebook work? And more importantly, why would anyone pay to watch it? Bloggers have been speculating just that since Sorkin, the writer of political dramas like "A Few Good Men" and "Charlie Wilson's War," started his own Facebook group about writing the film with the opening gambit:"I honestly don't know how this works ..."

I can't help but wonder if the story of Facebook really have the dramatic edge required to keep cinema audiences awake, let alone engaged ...

But, as with many of the most satisfying stories, there's a twist: Movie blog Slash Film is speculating that the film's script will be based on Ben Mezrich's book "The Accidental Billionaires: The Founding of Facebook, a Tale of Sex, Money, Genius and Betrayal."

They say they have "joined the dots" and noted that producer Spacey starred in "21," a highly enjoyable college caper based on Mesrich's book, "Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions," about the MIT blackjack team.

Can Mesrich's book, which comes out next month, and by extension a film, work the same dramatic magic on Zuckerman's Harvard story?

I wonder if Rudin and co. are already planning the sequel, "Twitter: Kutcher's Revenge"?

Would you watch a film about Facebook?
