After making two of the M3GAN movies, actress Allison Williams bonded with child actor Violet McGraw, who plays her niece onscreen, so much so that she won't allow her to watch her former show Girls.

"Violet has not seen Girls, nor will she ever," Williams said during a joint interview the two had with Entertainment Tonight. Turning to her young costar in the horror flick, she added, "You can see it when I pass on."

Williams then explained her issue.

"There's one scene — every time you and I talk about this show — there's one scene that pops into my mind's eye, and I just can't be in the same country," Williams said. "I have to be in outer space when you see it."

When McGraw protested, saying that she's 14, Williams shut her down.

"I know you're 14, and you are so adult," Williams said, "but also, thank God you're 14. Stay that way."

Williams did not specify the scene that bothered her, and Girls had its share of controversial ones. Airing for six seasons between 2012 and 2017, the Emmy-winning HBO series focused on four women in their 20s making their way in New York City. Sort of a younger version of Sex and the City, it addressed their romances, hookups, friendships, and careers. In addition to Williams, the cast included Jemima Kirke (Jessa), Zosia Mamet (Shoshanna), and creator Lena Dunham as Hannah.

One scene that was hyped as one of the HBO show's raciest when it aired was the first of the fourth season, on which William' character, Marnie, is the recipient of an "ass-motorboat" from Desi, who was played by future The Bear star Ebon Moss-Bachrach.

When it aired in January 2015, Williams told Vulture that she'd approached the job practically.

"Because of my wiring, I read it in the script and I went into total action mode. I got everyone together and I was like, 'All right, 'Grace [in wardrobe], you and me — we're going to come up with something so ingenious that he is going to feel comfortable.' I mean, think about where he is, right!" she said.

"It was our first day back of shooting and it was my birthday — everything was happening," Williams continued. "I grabbed the makeup girl and said, 'I want to smell like a cake,' so we put vanilla cream everywhere so everything smells good. And then I'm like, 'Grace, we're going to rig something invisible from the side but that feels like a pillow when he puts his face into it.' And, that's what we did! You wouldn’t know; it's total TV magic."
