I must confess at first I thought this teaser was a fake ... it seems more like a bunch of really good fan-made CGI scenes than an actual true movie.
Just like a few months before Episode I, there were tons of fake teasers and trailers (some even pretty good) on the Web.
Since I'm a bit on the younger side of the FSM forum population, I was 5 when I first saw the first Star Wars movie (before they called it "Episode IV - A New Hope") at a drive-in theater.
Ah man ... Life goes wayyyy too fast ...
