Aaron Sorkin admits he's working on "The Facebook Movie"Why would anyone not think Aaron Sorkin is working on a movie about Facebook? "You can't handle the truth!" That's the line Sorkin penned for Jack Nicholson in 1992's A Few Good Men. Nicholson might well have been speaking to some of our readers, who reacted poorly to the news that the West Wing writer was working on a movie about Mark Zuckerberg's creation. One begged us to uncover the fraud: "The BBC, the Guardian and New York Magazine are all over the totally fake-seeming Aaron Sorkin movie about Facebook. Please get to the bottom of this horrible joke." Sorry, you'll have to handle this: Sorkin himself confirmed that he is indeed planning a movie about how Zuckerberg and his Harvard classmates created Facebook.Rather, Sorkin's publicist, Joy Fehily, tells us, on his behalf. Or whoever answers her email. With all the layers of secretaries and managers and representatives in Hollywood, you can never tell. Yesterday, Sorkin's agent's assistant issued a nondenial, before politely informing us, "I have to hang up on you now." Likewise, the skeptics will have to hang up on any remaining doubts that Sorkin is behind this movie. Really, could anyone else do the movie? Sorkin is the master of the office drama, picking up on the details that make an inside-baseball story at once believable to insiders and entertaining to outsiders. If it had been anyone but Sorkin, we would have scoffed, too.
