Universal Studios has just released the second trailer for Scott Pilgrim Vs. The World on its Facebook page. The trailer was originally going to premiere in front of the comedy, Get Him to the Greek, but the studio offered to release it online first if the film could get 100,000 Facebook fans.

Social networks like Facebook and Twitter are becoming increasingly integrated into promotional campaigns for feature films. For instance, Disney premiered the first trailer for Alice in Wonderland on Facebook and also used the social network to serve up exclusive character posters.

For the upcoming release of Toy Story 3, Disney/Pixar has gone all out, even creating faux-vintage toy commercials for YouTube.

Universal’s strategy with Scott Pilgrim is unique in that it asked users to become fans of the film before it launched the trailer. The director of the film, Edgar Wright, announced this incentive on his Twitter account.

You can check out the second trailer for the film below:
