Not all of them have approval, and the way it works is they only have to approve the artist one time. Once they've said yes, it's just up to me and the licensing folks at Fox to make sure the likenesses are appropriate. And yes, there have been some artists who've been shot down, or about whom some cast members have complained. But I don't want to get into that...

What's your favourite Buffy character in the comics?

Every time I'm asked this I have a different answer, but right now it's Buffy. She's the one I find most compelling, if only because of the current arc. I'm realising there are aspects of her we've still never gotten into, and I have renewed interest in doing so.
