During the interview, Wilde talked about letting the cast give creative input on “Don’t Worry Darling,” and she has good reason. “They’re responsible for creating the character’s life, so they bring in a lot of ideas,” she told the outlet.
In the film, Alice is one of the few who begins to question this perfect community and begins to look for secrets it might be hiding. As you may have seen in the trailer, the crisis she is going through causes her to try to harm herself, and a glass window begins to press her against the wall. The movie isn’t out until the end of next month, so we don’t know if that part is real or a hallucination, but it’s eye-catching.
In the film’s world, the website reports that Alice can be heard humming “a mysterious tune”, which is a prominent part of the soundtrack. While character discussions were ongoing with the cast, Wilde said that Styles called her and asked, “What’s the trigger song? Like, what’s the tune?” She told him that someone wrote on it, but asked if he had any ideas. She speaks:
“Five minutes later, he sent me a demo from his piano, and that’s what ends up in the movie. He called me and said, ‘What about this?’ And I said, “That’s right. Right. And that’s really crazy when you’ve done it in five minutes.”
From the context here, it seems like this tune could be what triggers Alice to wake up from her carefully orchestrated existence. An example of this is how “All Along the Watchtower” activates memories and reveals the Cylons in “Battlestar Galactica”, affecting the plot significantly.
