Patti LuPone has joined the cast of Marvel’s upcoming series Agatha: Coven of Chaos.

According to Deadline, who broke the story, the legendary actress is believed to be “playing a witch”.

LuPone is best known for her work on stage, winning three Tony Awards and two Olivier Awards. Recently, she’s garnered critical acclaim for her various roles in Ryan Murphy dramas such as American Horror Story, Pose and Hollywood.

Coven of Chaos will see Kathryn Hahn reprise her WandaVision role as the titular spellcaster, Agatha Harkness, with Buffy the Vampire Slayer star Emma Caulfield Ford returning as Sarah Proctor/Dottie Jones.

The cast also includes Joe Locke (Heartstopper), Aubrey Plaza (The White Lotus), Ali Ahn (Supernatural), Maria Dizzia (Orange is the New Black) and Sasheer Zamata (SNL).

Plaza is “believed to be playing a villainous role”, stated Deadline, while Ahn and Dizzia have also been cast as witches.

Details are scarce on Locke’s role, although rumours have suggested that he will be playing Marvel Comics’ most iconic gay superhero, Wiccan, who also happens to be the son of Wanda Maximoff.

The Disney Plus series was confirmed to be in the works in November 2021 with Jac Schaefer, head writer and executive producer on WandaVision, returning in both roles.

Hahn’s character memorably debuted as Agnes, the charismatic yet nosey neighbour of Wanda Maximoff (Elizabeth Olsen) and Vision (Paul Bettany).

It was later revealed that she is a powerful witch called Agatha Harkness who has studied magic for centuries. Enraged with Wanda’s magical prowess, Agatha attempts to steal her chaos magic (to no avail).

Coven of Chaos will presumably take place after the events of WandaVision, which culminated with Wanda magically trapping Agatha as her intrusive neighbour persona in Westview.

It is expected to premiere in late 2023.
