Teaser trailer for Fincher's 'The Social Network'

Last week we saw the first poster for David Fincher's upcoming Facebook movie "The Social Network," and now we get a first feel for what is going on in the movie. A first teaser trailer is now online.

This really is a teaser, primarily because it only features text and dialogue. Luckily, it works, managing to at least get me more and more curious about this movie, which opens in theaters Oct. 1, 2010.

Jesse Eisenberg plays Facebook CEO Mark Zuckerberg, while Justin Timberlake will play Napster co-founder Sean Parker. Andrew Garfield will portray Eduardo Saverin, one of the site's co-founders.

The film obviously chronicles the birth of Facebook and the site's fascinating increase of users, as well as how the creators dealt with all this sudden success. Aaron Sorkin penned thr script. Enjoy!
