The Social Network, aka "The FaceBook movie", is a film about the creator and creation of Facebook and is due out in October from director David (Fight Club) Ficher. Written by Aaaron Sorkin, best known for The West Wing, and based on a book by Ben Mezich, The Accidental Billionaires: the Founding of Facebook. 

The film is described as a comedy-drama but the new trailer seems to cast it as a "who invented Facebook drama". Even it it doesn't look as if it is going to be about how to create a website using PHP, it does look promising...
