Warning: This article contains a minor spoiler from M3GAN 2.0. Kate Bush continues "Running Up That Hill" of pop culture notoriety. After Stranger Things season 4 gave her 1985 song a boost in the streaming charts almost four decades later, M3GAN 2.0 writer and director Gerard Johnstone picked another Bush piece — 1988's "This Woman's World" — to feature in his movie. The first M3GAN, released in 2022, went viral for a number of reasons, one of which was a scene that saw the campy protector-turned-killer robot singing David Guetta and Sia's electronic dance hit "Titanium" to the character of Cady (Violet McGraw). For this moment's spiritual successor, the sequel sees M3GAN, now reconstituted in a new 'bot body, singing "This Woman's World" to her creator, Allison Williams' Gemma. Johnstone tells Entertainment Weekly he had a different song in mind, but only because the script originally had different circumstances leading up to this musical moment. He doesn't want to reveal what that song was because "we got approval for it," he notes, and doesn't "want to speak ill." "When the script changed and that scene became more about Allison's character contending with what a failure she'd been," Johnstone explains, "it was really about being a mother." M3GAN 2.0 picks up two years after the events of the original. Gemma is now advocating for governmental regulation of AI at a time when AMELIA (Ivanna Sakhno), a new killer robot made from stolen blueprints for M3GAN, is killing anyone involved in her creation. To stop her, Gemma brings back M3GAN herself, now in an upgraded body. Williams previously explained how the team knew everyone's favorite viral sensation needed to dance and sing again. Johnstone compiled a playlist of about five songs that were in contention to become the new "Titanium." Want more movie news?

"'This Woman's Work' has such an unusual beginning to a song that it was the clear winner, even though it doesn't have the recognizability of 'Titanium,' for example, from the first film. It wins just because it's so odd. So I had to fight for that one a little bit, but I had everyone's trust at the same time, and I think everyone was very happy with that in the end." When it came to securing the music rights, James Wan, a producer on the M3GAN movies through his company Atomic Monster, tells EW, "I think the first movie helped. Do you know what I mean? I think M3GAN is such a fun platform for people to want to come and play with us on. So I think it just gave us a lot of leverage to ask for things." M3GAN 2.0 is now playing in theaters.
