"YOU DON'T GET TO 500 MILLION FRIENDS WITHOUT MAKING A FEW ENEMIES," reads the tagline on the first official poster for "The Social Network," the upcoming Columbia Pictures film about the origins of Facebook.

The all-caps text covers the entire poster, superimposed over the face of young actor Jesse Eisenberg, who wears an expression of awe on the cusp of metamorphosing into malevolence. In "The Social Network," due in theaters this October, Eisenberg plays Mark Zuckerberg, who founded Facebook in his dorm room at Harvard University and ultimately turned it into a digital empire with nearly 500 million members. In a skinny side bar on the poster–which is otherwise dominated by Eisenberg's face, tousled curly hair, and sloppy gray hoodie–the title "The Social Network" is laid out in the manner of Facebook's own font and navigation bar, with the movie Web site depicted as though it had just been typed in a search box.
