Reprising her role as the witch everyone loves to hate, Kathryn Hahn says it makes “perfect sense” and that she will continue the story.

The “Agatha Always” star, who first introduced Agatha Harkness to the world in the hit 2021 Marvel series “WandaVision,” said the rich complexity of her character excites her.

“It’s so juicy. You can see her as a simple evil witch, but she’s not. Nobody’s evil,” Hahn said in a recent interview with The Associated Press. “There’s always something they’re covering up, that they’re putting all these layers on top of, so it was fun to try to keep the mask on with all these meteors of truth pounding on that core.”

The Marvel Television series, premiering Wednesday on Disney+, picks up after “WandaVision” as Agatha forms a makeshift coven to travel the mythical Witches’ Road on a mission to reclaim her powers. Although Elizabeth Olsen’s Wanda Maximoff/Scarlet Witch Hahn said she felt empowered by the role because she captured Agatha’s magic in “WandaVision.”

One symbol that has become a crucial part of her character is the Neopagan triple goddess — the maiden, mother and crone as depicted on a brooch Agatha wears in both shows. Hahn says those symbols of transformation in the female life cycle are reflected in her own life.

“When I started this, I felt like I was walking through a portal into my old woman territory, whatever that means, and it felt really powerful to feel wise as I was going through this journey as a woman,” Hahn said.

In addition to references to Neopaganism, Wicca culture and other witchy motifs, “Agatha All Along” is filled with allusions. Various films, television shows, musical groups and more permeate the show’s otherwise spooky aesthetic, but none are more prominent than “The Wizard of Oz.”

Jac Schaeffer, the series’ lead writer, director and executive producer who also created and wrote “WandaVision,” said the 1939 film felt like a natural touchstone. “We’re in the land of witches,” she said.

“It was clear early on that it had to be a quest structure. And for me, the movies I love from my childhood are all quests,” Schaeffer said. “Once we locked into that structure, it was like, ‘How many allusions can we put in there and what makes sense and what’s delightful, what’s witchy enough for us?’”

Schaeffer said the series also references Fleetwood Mac and Kate Winslet in the gritty crime drama “Easttown Mare” And “Big Little Lies,” which she described as a “prestige lady drama soap” where everyone has “sweaters and beautiful hair.” She also said that the group on that show, led by Reese Witherspoon and Nicole Kidman, is a coven unto itself.

The references work because Agatha is “such a performer,” Hahn said — and perform she does. In addition to borrowing from “WandaVision’s” penchant for allusion and replicating aesthetics, “Agatha All Along” also features another catchy tune that the cast sings throughout the series.

Hahn, along with the ensemble cast, including Patti LuPone, Aubrey PleinJoe Locke, Sasheer Zamata, Ali Ahn and Debra Jo Rupp sing a memorable number that opens a door to The Witches’ Road. Emmy-winning songwriting duo Kristen Anderson-Lopez and Robert Lopez, who also wrote the viral sensation “Agatha All Along” for “WandaVision,” penned the song.

Although some cast members said they were initially nervous about singing for LuPone, a Broadway legend, the three-time Tony winner insisted everyone in the cast could sing well and blend their voices together well.

“It’s magical being in a choir. Sometimes the fates just come together. Every member of this coven had to pick up an instrument or we had to sing, and it all sounds amazing,” LuPone said. “Sometimes things are meant to be. I think this was meant to be.”

The coven’s close on-screen bonds seem to have grown off-camera, too. Hahn said the group developed a close bond while filming in Atlanta.

“Everyone is such a powerhouse in their own way that it was really easy to come to work. Everyone was doing their best because we were all so excited to work together,” Hahn said. “We just sat in a circle on stage every day, telling stories and talking about what we were going to eat next. It just became a dream.”

As the cast and creatives behind the series await the two-episode premiere, Schaeffer said she’s holding her breath as eagle-eyed fans dissect trailers and theorize about the plot. While she once thought “WandaVision” would be a “huge flop,” Schaeffer said she has confidence in the show.

“What ‘WandaVision’ taught me is that it all shakes out a little bit,” she said. “Not everyone is going to be happy, but the majority of people, I think what they really want is the ride and I feel confident that that’s what we’re delivering with ‘Agatha.'”
