I heard about this movie being made a couple of months ago but this is the first time I have seen a trailer for it which was released on July 15th. The movie is titled "The Social Network" and it is based on the founders of Facebook and the trials they faced making the social networking website what it is today. The leading actors in the movie include Jesse Eisenberg (from Zombieland) who plays Mark Zuckerberg, and Justin Timberlake who plays Eduardo Saverin.
The movie's expected release date in theatres is October 1st, 2010 for North America.
