Back to Heaven
There was a time when Joss Whedon was busy with screenplays for movies, and directing and producing and writing for two TV shows. Those days are over.
Firefly well deservedly got cancelled after a only few episodes. Buffy had to move from the WB to UPN in its last season. His Giles back home in the UK spinoff series never got off the ground. And on top of this, Thursday he got the message from the WB big heads. No more Angel after this current fifth season. That leaves him with enough time to make a nice concluding story line.
But yikes, he wants to turn Firefly into a feature length movie. Bad idea.
