First off, David Fincher is the guy that directed Fight Club.  If that's not enough right there, he also directed Se7en, Panic Room, and Alien 3 (which is better then everyone thinks),  Granted, he's been on bit of a downward spiral since his last couple of movies have been Zodiac and The Curious Case of Benjamin Button.  So he's like a band that started out really strong and is kinda fizzing out.

Secondly,  yup, they're making a movie about the Facebook story called The Social Network.  Trent Reznor was planning on taking a break after his last Nine Inch Nails tour, but David Fincher asked him to write the score.  So he cancelled his vacation and went to work and he has this to say, "Speaking of the film... it's really fucking good. And dark!"

Thirdly, a new trailer has been released (below) and used the Scala & Kolacny Brothers’ cover of “Creep”.  It really makes the movie look more creepy and while I'm typically not a "check out this video guys!" guy, you really need to check out this video.
