Movie on Facebook creators - by Fight Club director David Finch?

A movie on the founders of Facebook is in plans to be directed by David Fincher - the director of Fight Club, The Curious Case of Benjamin Button - and written by Aaron Sorkin - who has written Charlie Wilson's War, A Few Good Men, Studio 60, and The West Wing. >>

Umm... how is there supposed to be a story on that? They're still alive, they gained fame by inventing something... Aaron Sorkin - his works involve a lot of witty banter, whereas David Fincher's films seem quite heavy. Anyhow the combination seems to lead to an epic film... Hmm. Lucky SOBs.
