The Social Network is based off the true events surrounding the invention of Facebook and the animosity that it creates between its co-founders. This trailer is one minute and change, and features just random snippets of dialogue as we slowly zoom out to see Jesse Eisenberg's face.

Honestly, I was trying to come up with something interesting to say, but nothing of any value can taken out of this. A dialogue heavy movie like this probably didn't need a teaser trailer, but at the same time, I'm interested because it's written by TV vet Aaron Sorkin and I like the cast. Still, for a movie like this, the trailer should have had a bit more substance to it; Facebook will not sell this movie alone.
Regardless, I know I'll be there when The Social Network opens October 1, 2010.
