I just watched the 2008 American horror/sci-fi film Cloverfield, and it was amazing. Really, long time since I last saw such a great film. Basically, it is about a monster attack against Manhattan, filmed with a amateur camera by a couple of friends who happened to witness the whole thing. The film includes the time from a couple hours before the attack started, until Beth and Rob, the last holders of the camera, have a bridge crashing down above them, rocks falling down and then the film stops. The greatest part of the film is probably the work around it, though; the characters have fictional MySpace pages, there are websites for fictional products that featured and so forth. Also check out the IMDb FAQ for the film (AFTER you’ve seen it!).
