"Supernatural" has had a rabid following on the CW for seven seasons now. Add the equally rabid following of "Buffy the Vampire Slayer" into the mix, and there just might be a number of new viewers to Friday night's episode.
"Buffy" actors James Marsters and Charisma Carpenter are playing a married couple in the episode, and fans like Amanda (a.k.a. "Gaelicspirit") who recaps "Supernatural" on Whedonverse.net can't wait to watch.
"I'm looking forward to seeing the actors who brought us 'Cordy' and 'Spike' for so many years ... if only to see James Marsters without the bleached hair and cockney accent," she said.
"[Carpenter and Marsters] always turn in great performances, and the last time these two met on screen (during the fifth season of 'Angel'), their chemistry snapped off the screen!" said Whedonverse.net editor Kristen Dollar.
CNN Geek Out spoke with Sera Gamble, executive producer of "Supernatural" to find out more about the pair's appearance:
CNN Geek Out: Tell us about Marsters and Carpenter's roles in the episode.
Gamble: Charisma and James are a married couple going through a contentious separation. Sam and Dean come to town investigating some gory deaths (actually, some of our grossest to date). They realize Charisma's character is behind them, and that she's actually a very old, powerful witch exacting revenge on her husband. They end up being put in the role of unlikely mediators.
CNN Geek Out: Was it a conscious decision to hire two actors from "Buffy," or how did that come about?
Gamble: The CW contacted [executive producer] Bob Singer and me to say they felt like the witch couple would be a good opportinuty to cast high profile actors. Our casting directors, Robert Ulrich and Alex Newman, worked tirelessly to put together ideas that would be appropriate for our show. They came up with the idea of trying to get actors from Buffy– they understand how special that show is to much of our audience. We were thrilled that Charisma and James both agreed to do it.
CNN Geek Out: What was it like seeing these two back together on set?
Gamble: I've heard nothing but great things about both of them. They're talented and sweet. And their work in the episode is hilarious.
CNN Geek Out: Are there big "Buffy" fans in the cast and crew? Did it have an influence on "Supernatural?"
Gamble: Of course! Many of us are big fans. It's just a fantastic show, the kind of show that has sort of seeped into TV's collective consciousness. And because the vision of that show was so clear, in our early seasons, we were able to use it as a guide in creating a separate identity for "Supernatural." Everyone here has a ton of respect for "Buffy."
CNN Geek Out: Might we see more of these two in the future?
Gamble: The episode was written as a one-off. But characters survive the episode, so I'd say if there was a good story pitch and the actors were game for it, there could always be a chance of seeing them again.
