If Facebook were granted terra firma, it would be the world's third largest country by population. FACT. Where can one get such incredible knowledge? From The Social Network's interactive trailer.

Yes, following in Scott Pilgrim's footsteps, The Social Network has got itself a brand new trailer. And it's interactive. And stuff. Want to waste your life clicking links, poking Jesse Eisenberg, and looking at photos of people cooler than you? Screw Facebook, this is way better.

Boasting around 40 fried slices of solid info, the interactive factoids span everything from director David Fincher and Aaron Sorkin's script to the history of Facebook itself - who the hell is Eduardo Saverin?

To find out that stuff and more besides, read on for the full video (which is on the movie's official site). The Social Network is out in UK cinemas on Friday 15th October. And judging by the reactions at Toronto, it's awesome. But more important than that: it's interactive.
