That '70s Show star Debra Jo Rupp has joined the cast of Marvel's upcoming WandaVision spinoff, Agatha: Coven of Chaos.
The series, which centres around Kathryn Hahn's villainous WandaVision character Agatha Harkness, is scheduled for a winter 2023 release on Disney+.

Caulfield recently provided fans with an exciting update and revealed that production for Coven of Chaos began in November, adding: "The cast is so good. I start doing some stuff next week. I know a little bit, but I can't say anything.
"I can't tell you what to expect, because that would reveal something. I know little, just enough to keep me in the right zone."
Rupp will reprise her That '70s Show role soon, returning as Kitty Forman for the sitcom's spinoff series That '90s Show on Netflix later this month.
She will be joined by her on-screen husband Red (played by Kurtwood Smith) and some other returning characters.
Agatha: Coven of Chaos is set for release in winter 2023. WandaVision season 1 is streaming on Disney+. That '90s Show premieres on Netflix on Thursday, January 19.
