It's a throwaway moment, but the kind that says worlds about the character's mindset. Mark is out the door so fast, he doesn't even realize it has snowed until his socks and sandals are ankle deep in the stuff. But it's all just names and pictures until a roommate comes to him one day with a question that gives Mark a moment of inspiration: The website needs to do something. Zuckerberg is still obnoxious, though, and devious, too: When he's approached to work on a socializing website for a couple of golden-boy jocks, he stalls and tries to develop one of his own. Their hot-or-not prank gets so many hits, it crashes Harvard's server, and the dweebs are briefly campus celebs. Zuckerberg's revenge? He hacks some school photo archives and enlists his best buddy in a dumb, sexist online stunt: They start using complicated mathematics to rank the girls at school. But boy does it click along, from the moment Zuckerberg (Jesse Eisenberg as a cold-eyed, awkward boy genius) decides to get back at a girlfriend who dumps him during the opening credits.

The story of how Facebook was invented, almost accidentally, in a Harvard dorm room should have been near-impossible to film - computer geeks, code-writing, legal depositions. The film opens across the country today, so. The speculation was that he was trying to burnish his reputation before the movie tarnished it. A week ago, Facebook founder Mark Zuckerberg gave the Newark, N.J., school system $100 million on the same day the movie The Social Network opened at the New York Film Festival.
