As writers of The Watcher's Guide and Angel Case files, was it hard to prise all those dark secrets from the cast and crew?

Jeff: Not at all. Really you just need one dark secret, and then the rest can be blackmailed out of them quite easily (laughs)

The actors and crew know that when we're there, we're doing an officially licensed book. We have the permission of the production company to be there, and anyone we talk to is going to have a chance to look at their interview and remove anything that they would rather not have show up in print. So they're mostly very open with us. They're all hard-working and dedicated professionals who really put a lot of thought and effort into whatever their craft is, so for the most part they're happy to share with us.

Nancy: The first time we went up to the set, the cast and crew were a little uncertain of who we were. As the show's fame has grown, they're used to seeing reporters and photographers coming by. But there's a difference between someone looking for a story and someone who has a professional interest in presenting the show to the rest of Buffydom.

That's where we come in. We're not looking for dirt (not to share, anyway!) We're looking for interesting tidbits and bits of detail we can tell the fans, but not at the expense of the people we are observing.
