Aaron Sorkin was an interesting choice, but what if the Zuckerberg movie had been more fanciful, like the Royal Tenenbaums? Bill Murray, Angelica Huston and Danny Glover play the lawyers. Young Luke Wilson to play Zuck and Owen Wilson to play his wacky sidekick Sean Parker. Gene Hackman would have made a great Harvard president! There would have been an opportunity for some fun dialog with the Winkelvii. 

There would have been a lot of songs, old Beatles and Beach Boys tunes, and Zuck would have had a real girlfriend who loved and nurtured him, instead of having one who was pissed off. 

Maybe the Coen Brothers? You gotta know someone would have gotten murdered, maybe a lot of people, but it would have been fun anyway. Javier Bardem would play the gunslinging Zuck, with Steve Buscemi as his nincompoop sidekick. The Dude, played by Jeff Bridges, could do a walk-on, bathrobe and a milk carton. 

Tim Burton! Now that would have been coool. Johnny Depp would be Zuck for sure, and the music would be by David Byrne Danny Elfman. Helena Bonham Carter as Zuck's girlfriend, and instead of being nurturing or angry she'd be on drugs, but would wear those cool dresses and dance a lot and generally be puzzled (in a nice way) by his nerdiness. 

There are so many possibilities. Francis Ford Coppola, or his daughter Sophia. Martin Scorcese could direct Matt Damon and Leonardo DiCaprio in the leading roles. Matt could ask Leonardo how do you like them apples. And where was Scoble in all this? Obviously Philip Seymour Hoffman would play him.  

There were so many ways to go, and maybe we can try them all. Zuck is only 26, and people love sequels!
