From cinematical.com: Joss Whedon Says No More Serenity When Joss Whedon's Firefly television show met an early, unfortunate demise after only one season, his fans roared their disapproval. The combined strength of their voices was heard, and the result was a continuation of the series via a theatrical feature film called Serenity. Fans rejoiced. Unfortunately, very few others rejoiced, and the movie was met with a very lackluster box office performance. Despite this, rumors of a second season (licensed by another studio or some outside financing group) or even a second film have persisted -- perhaps because of the successful fan uprising the first time around. Joss Whedon has finally met those rumors head on, and flatly denies any hope for a return to the Firefly universe. Whedon bluntly declared: "There's no sequel, no secret project regarding Serenity or some such and I'm not even sure how anyone thought there was talk there. So let's put that to bed and smother it with a pillow." Sorry, fans, it looks like the movie was your last hurrah. Well done on bringing the first film about, though, and congrats on being truly dedicated, exciting fans. All directors should be lucky enough to land fans like you.
