Kathryn Hahn on Agatha Harkness’ Future in MCU Crossovers

Kathryn Hahn’s Agatha Harkness definitely made waves with her Marvel Cinematic Universe debut in WandaVision. Her manipulative witch character not only shook things up for Wanda Maximoff/Scarlet Witch but also had a ripple effect across the Multiverse. Now, Agatha is set to return in her own series next month, titled Agatha All Along. However, the long-term future of this fan-favorite antagonist in the broader MCU remains uncertain, though Hahn has some insights into what she hopes to see next. In an interview with Rolling Stone, Hahn expressed that she wouldn’t be against Agatha appearing in upcoming crossover films such as Avengers: Doomsday and Avengers: Secret Wars, but she believes it would only happen if it was truly essential.

“I think I’d only be asked if it was necessary and juicy,” Hahn said. “So, who knows? The craziest, most perfect, side-door entrance to this world is to be a witch. It feels wicked step-sister-y. And I really like it like that.”

Despite her enthusiasm, Hahn is clear that Agatha is far from a mere “side character”. In the same interview, Hahn was asked about the challenges of transitioning a “scene-stealing sort of side character” like Agatha into a leading role in Agatha All Along. Hahn firmly believes that Agatha has always been more significant. “I was going to say, who are you calling a side character?” she laughed. “That’s definitely a tricky thing. But from the beginning, we always joked that it would just be so annoying to Agatha Harkness that she wouldn’t have her own fricking show.”

Fortunately, Hahn didn’t have to wait long to know that Agatha would indeed get her own show. She revealed that she found out while working on Glass Onion: A Knives Out Mystery. “I remember [WandaVision head writer and Agatha All Along showrunner] Jac Schaeffer saying ‘God, I’d love to write for you again.’ We both kept saying, ‘we have unfinished business’ to each other at the end of WandaVision,” Hahn shared. “I didn’t even know if it necessarily meant something in this world or somewhere else, but our minds melded. I loved her point of view and her sense of humor. And this character just felt very easy.”

Further elaborating, she continued, “Then over the summer, when I was in Serbia shooting Glass Onion, the Knives Out movie, I got a call from [Marvel Studios co-president] Louis D’Esposito saying, ‘How’d you like your own Marvel show?’ — a call you never get. My heart was pounding. I could barely understand what he was saying. I knew what it meant, but I just kept finding ways to minimize it for myself until the first day of shooting. Someone had put a sign on the window of my trailer that said, ‘welcome to your first day on your very own Marvel show’ and I burst into tears. It was very, just very exciting, especially with a character that you just love and just want to explore every nook and cranny.”

The storyline of Agatha All Along is intriguing. The official description reveals: “In Agatha All Along, the infamous Agatha Harkness finds herself down and out of power after a suspicious goth Teen helps her break free from a distorted spell. Her interest is piqued when he begs her to take him on the legendary Witches’ Road, a magical gauntlet of trials that, if survived, rewards a witch with what they’re missing. Together, Agatha and this mysterious Teen pull together a desperate coven, and set off down, down, down The Road…”

In addition to Kathryn Hahn, the series stars Joe Locke, Sasheer Zamata, Ali Ahn, Maria Dizzia, Paul Adelstein, Miles Gutierrez-Riley, Okwui Okpokwasili, with Debra Jo Rupp, Patti LuPone, and Aubrey Plaza. The executive producers are Kevin Feige, Louis D’Esposito, Brad Winderbaum, Mary Livanos, and Jac Schaeffer. The directors for the series include Jac Schaeffer, Rachel Goldberg, and Gandja Montiero.
