INXS's "Never Tear Us Apart" is used during one of the erotic scenes, but distributor A24 struggled to get the rights for it. Director Halina Reijn loved the scene with the song and tried many other songs, but nothing worked. After a few sleepless nights, she complained about the situation to Nicole Kidman, who told Reijn to give her a couple of days. Kidman then managed to secure the rights.
The milk glass scene happened in real life to Halina Reijn's life: she once went into a bar by herself in Belgium, and ran into a very famous unnamed Belgian actor, 15 years younger than her, who ordered a glass of milk for her. She thought it was a very courageous thing to do, and wanted to reward him by drinking the whole thing, which she did, though it left her "a little nauseated."
Nicole Kidman won the Volpi Cup for Best Actress at The Venice Festival in 2024. Kidman had just arrived in Venice and was on her way to the closing ceremony when she was informed her mother had passed away. Kidman had to leave Italy immediately and did not receive the award in person, which director Halina Reijn accepted on her behalf.
In a 2024 interview with Cosmopolitan, Halina Reijn spoke about the importance of casting Antonio Banderas: "We really
wanted a husband that would be so hot, so masculine, so it wouldn't be about, oh, he cannot dominate her. That's not the problem. The problem is that she doesn't dare to ask for what she wants and needs. Just like all of us women often don't dare. We're just like, no, as long as he's having a good time, I'm aroused by his arousal. I also needed someone who could be equal to her. I couldn't believe when he said yes. You will see a lot of male actors, especially of his status, that will not play supporting to a female movie star."
