This awesome teaser trailer is sometimes running in front of screenings of Transformers in the States. Now, as good as Transformers was, it would be hard to keep my attention after that trailer.
It's probably a movie codenamed "Cloverfield", which J.J. Abrams is supposed to have been working on for a while now. No real details exist except that it's a big, dumb monster movie. Hooray! 'Round these parts, we loves us some big, dumb monster movies. Even the Godzilla remake, but only for that one scene where Jean Reno's does his Elvis impression.
Cute thing - the official site, which isn't referenced anywhere in that trailer, or on any other official sources, is tracking visitors using Google Analytics. This word-of-mouth campaign is being dissected, one visitor at a time.
