Speaking of which, the second serenity trailer is up at the Apple Quicktime trailers site.

To clarify the thread for those who seem to be confused about dates and such:

The movie comes out near the end of September 2005 (30th, I believe), and what we were discussing here were sneak-preview showings that happened many months in advance, one of which I was lucky enough to get tickets for.

I'm still going to see the finished film when it comes out.
