Joss Declared the End
Bad news: In this weeks Entertainment Weekly in the News and Notes section Joss Whedon announced some news: he has given up on the Firefly saga. Despite the film getting "some of the best reviews of the year", since it seems there is not a large enough audience that a studio/corporation belives in, and also since we did get the big movie, he has given up on Firefly. He is making two more films: Wonder Woman, and a thriller for Universal. He will make which ever one gets greenlighted first first.
