I think a lot of filmmakers have trouble portraying desire in a way that's taken seriously today, especially with the rise of the digital world, where information, opinions, and internet humor spread so quickly, and Night Nurse treats desire with psychological weight rather than irony or camp. Was it important to you to reclaim the erotic thriller as a serious genre rather than something people don't always take seriously?
I was thinking about this recently because Catherine Breillat is one of the filmmakers who inspires me most. Part of what makes her films work is that they're in French, which I think is an incredibly beautiful language. I actually think it's difficult to make an erotic thriller—or even a romance—in English because English can sound awkward or corny. That was a real challenge for me.
That's one reason I admire filmmakers like David Cronenberg and Atom Egoyan. They're English-language filmmakers, but they approach these subjects with complete seriousness. While there are moments in Night Nurse that I personally find funny, I wanted the overall tone to remain serious, in the spirit of a Catherine Breillat film. I wanted audiences to sit with discomfort and see what that experience feels like.
The film has been compared to films like Body Heat, In the Cut, Crash, and Babygirl—films I'd argue remain timelessly bold. Were there any filmmakers, writers, or artists outside of cinema that shaped the inspirations of the film?
I've already mentioned many of my cinematic inspirations, so I'll talk about the score.
Stephen and Sam, our composers, created a score I'm incredibly proud of. One major inspiration was Francis Ford Coppola's The Conversation. Although it's a very different film, it uses a recurring musical theme that returns again and again. I wanted to do something similar because hearing the same melody, even as the story becomes more intense, creates this feeling that you're trapped and can't escape. I also listened to the score from 3 Women constantly while writing. It has such an unsettling, strange atmosphere that helped put me in the right headspace. It also inspired us to make the flute a central voice in our score, paired with piano.
The relationship at the center of the film may not be universally relatable, but the psychological experience behind it certainly is, particularly through its exploration of the lengths we're willing to go for love and care. What do you hope viewers take away from the darker side of those impulses?
More than anything, I hope viewers come away with the feeling of the film. It's meant to take you on a ride. It's not a moralistic film, and it's certainly not meant to represent what it's actually like to be a nurse. It's really about interpersonal relationships and the ways caregiving exists within romance, friendships, and families. It's about the compulsive side of caregiving. In many ways, the phrase from that medical school billboard—"It's amazing to be needed"—captures the entire film in one sentence.
