Tony Head has revealed yet more on the future of Buffy and Ripper.

"Joss wants to make a movie," Tony told the ET Online website. "I'd love to make a movie. I don't think Sarah does at the moment, but who knows what is going to happen in two years' time. Joss' imagination is so wild, fertile and unstoppable, you know whatever it is going to be is cool."

As for Ripper, Tony suspects it won't now be happening until at least 2003.

"[It's] somewhere down the line. Joss really wants to do it. Jane Espenson has already written one script, and they are talking about putting six scripts together. [With Firefly, Joss] has quite a bit on his plate right now. It suits me because I have a fair amount on mine. I think possibly [it will happen] sometime next year."
