Just to show up David, I'm letting you know that the international trailer for Serenity has been released. (Be warned, something about that file, and all the mirrors I can find online, locks my computer up 1:43 in, just when the Serenity logo comes onscreen. Still worth it.)
Even better, is this line I found on the IMDB trivia page:
According to an interview with Alan Tudyk, this is the first movie in a three-picture Firefly contract with Universal.Three Firefly pictures? Excuse me, I'll be in my bunk.
