There’s a new interview with Brad Kern about Charmed, mostly the same, old, boring stuff except this paragraph:

Do you think there might be a slim chance the CW network would consider a spin-off? Maybe using the grown up children, Wyatt and Chris?

Honestly, no. What most of the fans probably don’t realize is that, last year, the show was all but dead. The new regime at the WB, in all of its wisdom, wanted a new direction if they were going to give it another year. They knew that Alyssa, Holly and Rose weren’t going to come back for a 9th season (no matter how much they got paid), so the network told me that the only way they’d pick the show up for an 8th season would be if I could come up with a way to build in characters that could potentially “spin off” for a 9th season. That’s how I came up with Billie and Christy, which convinced the network at the last minute to pick up the show. Personally, I think both Kaley and Marnette have done an amazing job coming into an existing series and giving it new life; yet, at the same time, it fundamentally changed the show from what it started out to be. But, that’s the business of television — do whatever you can to get picked up for another season.
