Joss Whedon posted on Whedonesque.com about directing an episode of Glee:
Hey kids and parents of kids and super-old, like ancestor-old-but-not-dead-yet-type people, just poking my oversized head in to say that the rumors are true... unless something very odd happens in the next few months, I will have the privilege of shooting an episode of GLEE. Why GLEE? Because I love cops, serial killers and gritty urban drama (I haven't seen the show yet). Why me? Because they're struggling and can't afford real directors. And to head off a few queries:
No, this doesn't mean Dollhouse definitely won't get a back nine. Our numbers mean that! But I kid. Okay, we're not exactly saving all the good stuff for 14-22, but nobody's closed the door. If D'House suddenly busts wide, huzzah, we'll still bring it, and I'll still go and direct an episode of Glee, because of my love of cops. These realities can co-exist. And possibly cross over, at least in fiction that I have wri - read. About.
With so many producers who are preening schmoes out there, Whedon is downright refreshing.
I admit, as a result, despite the numbers, I am rooting for eleventy billion episodes of Dollhouse. Or 17 seasons. Whichever comes first.
