Somebody tell the Browncoats - there might be hope for a second Firefly movie.
A recent interview with Alan Tudyk by Moviehole.net let slip an interesting piece of information, namely, that there was a pretty good chance that a sequel to Serenity would be made by Universal Pictures because the collector's edition DVD of Serenity is selling so well. Even if it's a straight to DVD release (which is something of a fad these days), it would probably still sell well.
We can only hope.
