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?

Move over Scarlett. The world's most famous bespectacled neurotic, Woody Allen, declared that the person he would most like to put in one of his movies is France's First Lady Carla Bruni-Sarkozy.

France's glamorous First Lady, Carla Bruni-Sarkozy is director Woody Allen's latest leading lady of choice.

"Without question, Carla Bruni!" declared the U.S. director on RTL radio in Paris Thursday.

"I'm sure she would be wonderful," Allen said through a translator. "She's got charisma, she's already acted so she's not unknown to an audience. There are a lot of ways I could use her though I don't have a story for her at the moment."

Of course, Bruni-Sarkozy is no stranger to the limelight: She was one of the world's highest paid supermodels in the 1990s, then reinvented herself as a musician and released three albums before wedding Sarkozy after a whirlwind three-month romance and becoming one of France's most well-known faces.

She made a brief film appearance in Robert Altman's 1994 fashion world black comedy, "Pret-a-Porter," as well as 1998 French comedy "Paparazzi" - but she has always appeared as herself.

The 73-year-old director is rumoured to be planning a visit to the Elysee presidential palace and to stay with President Nicolas Sarkozy and his wife. I wonder if he will ask her then?

Which world leaders' wives would you most like to see on the big screen? U.S. First Lady Michelle Obama? Queen Rania of Jordan? Cameroon's First Lady Chantal Biya?

Whoops! "Indiana Jones" star Shia LaBeouf let slip at an interview with the BBC for his new movie, "Transformers: Revenge of the Fallen" that the people behind last year's huge "Indiana Jones and the Kingdom of the Crystal Skull" are indeed planning a follow-up.

Harrison Ford cracks the whip as movie icon Indiana Jones.

Blink and you would have missed it, but here is what LeBeouf actually said during the BBC interview: "Steven [Spielberg] just said that he cracked the story on it, and I think they're gearing it up."

And why wouldn't Spielberg, Lucas et. al? After all the last Indy movie - which was released to salivating fans 19 years after the previous one, "Indiana Jones and the Last Crusade" - made just under $800 million worldwide.

Even so,  some fans were disappointed by Indy's fourth outing and I wonder just how much appetite there is for another film - even from hardcore disciples of the franchise.

That said, the thought of sitting in a cinema hearing the theme tune trumpeting and seeing Indy's fedora silhouetted at the beginning of a new movie is an enticing one.

Does the prospect of Harrison Ford cracking the bullwhip for the fifth time make you salivate or wince?
