LOS ANGELES Aaron Sorkin is about to get a whole lot of friends on Facebook.

Sorkin, one of the town's biggest writers and TV producers, is in negotiations to write an untitled film project about the founders of the popular social networking site that Scott Rudin will produce for Columbia.

Sorkin broke the news on Facebook when he opened his own account.

"I understand there are a few other people using Facebook pages under my name -- which I find more flattering than creepy -- but this is me. I don't know how I can prove that but feel free to test me," he wrote before going on to talk about the movie project.

"I figured a good first step in my preparation would be finding out what Facebook is, so I've started this page. (Actually it was started by my researcher, Ian Reichbach, because my grandmother has more Internet savvy than I do and she's been dead for 33 years.)"

Sorkin also asked the Facebook public for any stories relating to the site.

Facebook was founded by Mark Zuckerberg while studying at Harvard along with pals Dustin Moskovitz and Chris Hughes. At first, membership was restricted to Harvard students, then expanded to all Ivy League schools before going on to open up for all universities and high schools in Canada and the U.S. The site now has more than 100 million users worldwide.

The site has also generated its share of controversy, with persistent allegations and legal wrangling over whether the founders stole the concept for Facebook from UConnect, a social net that employed Zuckerberg during his college years. That dispute was settled out of court.

Despite offers in the billions of dollars, Zuckerberg has steadfastly remained independent.

Sorkin last wrote Charlie Wilson's War. He is perhaps best known as the creator of lauded NBC series The West Wing. Rudin has Revolutionary Road starring Leonardo DiCaprio and Kate Winslet and the film adaptation of the Broadway play Doubt coming out this fall.

"I feel about this introduction the way I felt about Sophie's Choice: It could have been funnier," Sorkin finished.
