While the script comedically name-drops other shows and movies—like the The Godfather, Pride and Prejudice and Zack Snyder's Justice League—there are multiple Easter eggs to The Wizard of Oz hidden in the set. A movie theater marquee shows that the 1939 film is playing in the doll world, but the inspiration didn't stop there.

"[The Wizard of Oz] does something that I wanted to emulate," Greta said in an interview, "which it's using these incredible sound stages and these painted skies and this sense of 'authentic artificial,' which I think is very beautiful and emotional."

The 39-year-old explained, "I think of the painted backdrop of the Emerald City as they go towards it, and we put in our movie, we have the pink brick road, instead of the yellow brick road. We also have beautiful painted backdrops of horizons. We executed it like they would have done in the ‘30s and ‘40s."
