Gellar's former boss, Buffy mastermind Joss Whedon, is getting out of the TV business — at least for the time being. According to Variety, Whedon has shuttered his Mutant Enemy production company because he says he has run out of ideas. "I spent a lot of time trying to think what my next series would be," Whedon said. "I couldn't think of anything. When that happens, it generally means something is just not working." For now, Whedon will continue to focus on features — including the forthcoming Firefly flick, Serenity. What does all this mean for the proposed Buffy cartoon? I'm told that remains on the drawing board.
