Kathryn Hahn is baring all for her latest Marvel project.

The actress, 51, stripped down for the first episode of the new Disney+ series "Agatha All Along," a spinoff of the Marvel series "WandaVision." In the first episode, her witch character, Agatha Harkness, awakens from a spell to find herself standing in her home completely naked. She then walks out of the house to talk to a neighbor, and her rear end is shown as she turns around to leave.

In an interview with Variety, Hahn revealed the nude scene was her idea.

"Well, I came up with it," she said. "I thought it was good to see her as stripped down, literally, as we possibly could, which spoke into her powerlessness at the present moment."

Marvel Studios president Kevin Feige, though, was apparently skeptical of the choice. In an interview with TVLine, executive producer Jac Schaeffer said the idea that Agatha would emerge from the spell naked was in the script, but originally, she would have grabbed a robe before going outside. Hahn, though, felt the character wouldn't take the time to get a robe and would simply leave the house nude.

"Kathryn was so up for it," Schaeffer told the outlet. "I love it because it is so firmly based in character. It is not exploitative. It's not sexual. It is about this witch and what her priorities are."

Hahn also confirmed to TVLine that she did not use a body double for the scene, in which Agatha's breasts are not visible. The moment is the first instance of female nudity in Marvel Studios history. The franchise has previously had some male nudity, including when Thor's butt was shown in the 2022 movie "Thor: Love and Thunder."

The Disney-owned Marvel Cinematic Universe has recently been pushing some boundaries after years of being known as family-friendly entertainment. In July, "Deadpool & Wolverine," which was filled with bloody violence and language, marked the first R-rated MCU film. In January, "Echo" was the first of Marvel Studios' Disney+ shows to be rated TV-MA, designating a show for adults that may be unsuitable for children under 17.

Review:Marvel's 'Agatha All Along' has a lot of hocus pocus but no magic

Last year, the PG-13 rated "Guardians of the Galaxy Vol. 3" also featured the first use of the f-word in a Marvel Cinematic Universe film. On "Jimmy Kimmel Live!" at the time, star Chris Pratt said he was "pretty excited" about getting to use the word in the movie.

"Kevin Feige talked to (director) James Gunn and said, 'Listen, you don't want to be the guy who's known for having the first f-word in your movie,' " Pratt said. "And James was like, 'Yes, I do! Don't you know me? That's exactly what I want!' "
