Good news: The shiny new trailer for Serenity is up, and it looks like it's gonna be great.
Bad news: The text in the trailer informs us that there are "Six rebels on the run", however, in the shot early on in the pilot's area of Serenity there are seven people shown. Even worse, Shepherd Book (Ron Glass), arguably one of the most interesting characters on the whole show, is nowhere to be found, even though his name is in the credits at IMDb.
Anyway, check it out if you haven't already. But Book better be in there.
