Kathryn Hahn became one of the newest Marvel stars last year when she debuted as Agatha Harkness in the Disney+ series WandaVision. Hahn’s performance was widely praised and her character became even more popular thanks to the catchy song Agatha All Along, which won the Primetime Emmy Award for Outstanding Original Music and Lyrics, and it was also nominated for the Grammy award.
Following the huge and quick popularity that Hahn earned as Agatha Harkness, Disney and Marvel Studious officially announced last November that a spin-off series — Agatha: House of Harkness — is in development, with Hahn set to reprise the titular role. Not much else is known about the series at this point, but the main actress offered the first tease:
“All I’ll say, in terms of a real great deflection of that question is that… There is something that does feel so badass to be playing like, you know, we think of a witch and you think of, you know, immediately you think of a woman who is loud, who is mysterious, who is dangerous because she’s complicated and she’s misunderstood. All of that stuff is a real turn on to me as a performer in terms of digging into this person a little bit more, very excited.” — Kathryn Hahn for Entertainment Weekly
Hahn first appeared in the premiere episode of WandaVision as Agnes, Wanda’s lousy neighbor. By the end of the series, it turned out that Agnes was actually Agatha, and that she was actually pulling the strings of everything that was happening to Wanda in Westview. It turned out that Agatha is a witch who wanted to get Wanda’s powers, and she also gave Wanda her official superhero name — Scarlet Witch — which was the first time that that name was mentioned in the MCU. After the final battle, Wanda defeated Agatha and punished her by turning her back into a lousy neighbor.
So, what’s next for Agatha? No one knows. Marvel Studios didn’t offer much information when the series was officially announced. It’s not even known if the series will be set after or before the events of WandaVision, and even the release date announcement also seems far, far away.
