The cast of the upcoming WandaVision spinoff series Agatha: Coven of Chaos has added another fan favorite TV star. Deadline reports that Debra Jo Rupp, who's best known for playing Kitty Forman in the hit sitcom That '70s Show, has just boarded the cast of Coven of Chaos. Of course, fans may remember that Rupp also played Sharon Davis (aka Mrs. Hart) in WandaVision, and it's presumed she will be reprising this role. Also returning from WandaVision are Kathryn Hahn as the titular witch alongside Emma Caulfield Ford as Dottie Jones. Other newcomers include Joe Locke, Aubrey Plaza, Ali Ahn, Maria Dizzia, Sasheer Zamata, and Patti LuPone.

Jac Schaeffer, who created WandaVision, is also back as a writer and executive producer on the spinoff. Schaeffer is also set to recit at least one episode, while it's been reported Gandja Monteiro will also serve as a director. The series will reportedly consist of nine episodes, akin to WandaVision and She-Hulk: Attorney at Law, and is expected to arrive on Disney+ in late 2023 or early 2024.

"The cast is so good. I start doing some stuff next week," Emma Caulfield Ford said in November, revealing that production was beginning sooner than expected on the show.

Of what to expected, she added, "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. I think it's all going to be really fun."

Meanwhile, Debra Jo Rupp is back as Kitty Forman on That '90s Show, the all-new series that serves as a follow-up to That '70s Show at the same house but in a different decade. Joining Rupp for the series is Kurtwood Smith, who's back as Kitty's husband Red Forman. While many other original stars of That '70s Show also appear, the series will primarily follow a new group of youths hanging out in the same old basement.

"It has been a gift. I mean, seeing all the kids come back," Rupp recently said in a BTS video about comign back to that role. "It was almost like no time had passed. We have like a mini-reunion every week. It's just been amazing."

In addition to her role in WandaVision, Rupp also spoke about the series with an appearance in the Marvel Studios: Assembled episode about the making of the show. Her other recent roles on the small screen include The Ranch, This Is Us, and Grey's Anatomy. She also appeared in the films Fair Market Value and The Social Ones.

That '90s Show premieres on Netflix on Jan. 19, 2023.
