God, I love J.J. Abrams. The marketing behind this film alone is genius, I can't wait to see it.
For fun, check IMDB. A person named MY_NAME_IS_VAN is posting, obviously a viral advertising campaign for the movie. He leaves just enough tidbits to make you really want to figure out what this is all about.
Also, Google Ethan Haas. It's amazing the amount of hype this 2 minute trailer is generating.
