It's the year's most memorable movie tagline: "You don't get to 500 million friends without making a few enemies." But in The Social Network, Aaron Sorkin and David Fincher may have made a few of their enemies of their own at Facebook. The film is an unflattering portrayal of Facebook CEO Mark Zuckerberg, chronicling his days as Harvard's nerdy boy genius, whose drunkenly-penned algorithm led to fallouts with friends, costly litigation and a whole lot of partying. While many of the events have been changed or invented for dramatic effect, the factual accuracy of the film didn't affect the box-office take: Facebook's story grossed more than $166 million worldwide in its first two months.
