According to Deadline, Debra Jo Rupp, from That ’70s Show, Friends and That ’90s Show, has joined the cast of Agatha: Coven of Chaos, the Disney+/Marvel WandaVision spinoff series starring Kathryn Hahn.
Rupp joins the cast, which also includes Joe Locke, Aubrey Plaza, Ali Ahn, Maria Dizzia, Sasheer Zamata, and Patti LuPone, in addition to Hahn, who is returning her role as the bad girl Agatha Harkness from WandaVision. Also rumored to be returning is Emma Caulfield Ford as Dottie from WandaVision.
Rupp’s part hasn’t been made clear, but it’s safe to infer that she might be revisiting the Mrs. Hart character she performed in the original series’ five WandaVision episodes.
