Charisma Carpenter and James Marsters will join the cast of Supernatural for an episode of season 7, which starts in a month. The stars of Buffy and Angel will make a guest appearance in an episode called “Shut Up, Dr. Phil.” Here is what the current showrunner Sera Gamble had to say:
“This episode is Bewitched gone wrong. [It was] all upside for this successful man [played by Marsters]while he was married to the witch [played by Carpenter], but now that he’s pissed her off, the whole town is paying the price.”
Season 7 is to premiere on September 23rd, on the CW, 9/8 c.
