It's so meta that The Social Network has a Facebook fan page. Aaron Sorkin adapts Ben Mezrich's 2009 book, The Accidental Billionaires, about the founding of Facebook. Starring Jesse Eisenberg, Andrew Garfield and Justin Timberlake, it's now just a question of how many of Facebook's 500 million members will leave their computers to see how the biggest time-suck in history began. Opens today, Friday, Oct. 1. Area theaters. Visit fandango.com.
