“It’s like I walked on the moon!” the actress said in a new interview with Jennifer Hudson.

Kathryn Hahn has been baring it all in Agatha All Along. The very first episode of the ongoing Marvel Cinematic Universe miniseries, which sees the actress reprising her role as the witch Agatha Harkness from WandaVision, finds Hahn getting buck naked. Far from being exploitative, the nudity in this scene was actually Hahn’s idea.

“When we see Agatha at the beginning, she’s completely without her powers,” Hahn told Jennifer Hudson in a new interview on the Jennifer Hudson Show. “She has to bust out of the spell with help from some mysterious characters. When she first realizes it, I think the description was like, ‘she puts on a robe and goes outside.’ I was like, ‘I wonder if she would put on a robe? Because she’s in a feral state.’ I think she was just feral. She wouldn’t even be thinking of who she is.”

After all, when the show begins, Agatha has been living under the spell of Wanda Maximoff (Elizabeth Olsen) for three years, reflecting the real-life time between WandaVision and Agatha All Along. When she finally breaks out of the illusion, she’s eager to regain her powers and her sense of self. The nudity in that first episode reflects the mindset that will set Agatha on a quest down the dangerous Witches’ Road in search of those things.

“That’s commitment,” Hudson said with awe.

“There was a lot of double-sided tape,” Hahn said with a laugh. “So every time I moved it was like squeak, squeak, squeak. But it was deemed necessary.”

Hahn’s nudity in the Agatha All Along premiere was rooted in story and character, but it still marked a first for the MCU. Disney’s superhero franchise typically stays very chaste, but witches live to break the rules. Although the show exists within MCU continuity, it also draws on pop culture influences from outside superhero comics. The show references iconic witches like Glinda and the Wicked Witch of the West from The Wizard of Oz (who are coincidentally coming soon to a big screen near you), not to mention Stevie Nicks.

“You do realize you’re the first woman to show butt in the Marvel Cinematic Universe?” Hudson asked.

“I didn’t know it at the time, but also to know it’s behind Thor is pretty great,” Hahn said. “Thor and me. Just our butts encased in gold — that’s my dream.”

Hudson couldn’t give her that, but to commemorate Hahn’s achievement, the talk-show host presented her with a plaque for being “First Woman To Show Butt in the Marvel Cinematic Universe.”

“It’s like I walked on the moon!” Hahn said enthusiastically.
