Bref, the modern film industry is terrified of celluloid. When a first-time director approaches a studio and asks to shoot their debut feature on 35mm film, the executives immediately calculate the shipping costs, the processing fees, and the horror of the blind daily rushes. They will offer you a high-end digital sensor and promise that the colorist can “add grain in post.” But Celine Song refused the compromise. For Past Lives, shot on a $12 million budget, she demanded actual film. Why? Because you cannot digitally manufacture the weight of time.
Past Lives is a film constructed entirely around the concept of in-yun—the invisible thread that connects people across lifetimes. It is a story about the relentless, melancholy passage of years. Song understood that to capture time, you must use a medium that is physically affected by it.
Anatomy of the Craft: The Infinite Medium
There is an infinite, almost ghostly quality to film emulsion that digital grids simply cannot replicate. To achieve this texture, Song partnered with DP Shabier Kirchner. They shot the entire feature on KODAK VISION3 500T 5219 film stock, running it through a Panavision Millennium XL 35mm 3-perf camera.
C’est magnifique how Kirchner manipulated the stock. To emphasize the emotional distance and the weight of memory in certain scenes, he push-processed the film by a full stop, driving up the contrast and forcing the grain to dance on the screen. But when the narrative demanded intense, suffocating intimacy—like the heartbreaking late-night conversation in bed between Nora and Arthur—he pull-processed the film by two stops. This flattened the contrast, smoothed the grain, and allowed the Kodak emulsion to capture the impossibly subtle hues of their skin in the low light. They paired this stock with vintage glass, specifically Panavision Ultra Speeds, to ensure the image felt unstuck from any specific, crisp modern era.
Directing the Performance: The Theater of Constraints
So, how does a first-time director convince producers to pay for a 35mm workflow on a $12 million indie budget? She leverages Système D. She promises absolute discipline on the floor.
Song brought her extensive theater background to the set. In the digital era, directors are lazy; they leave the camera rolling and force the actors to find the scene on the tenth take. You cannot do this when every second of film stock costs money. Song and Kirchner rehearsed the blocking relentlessly before the camera ever rolled. The actors were drilled until the scene was deeply embedded in their muscle memory.
When it was finally time to shoot, Song knew exactly what she needed. She often moved on after only two or three takes, maintaining a remarkably low shooting ratio for the entire production. She proved that the constraints of film do not restrict the artist; they focus the vision. Past Lives is a masterpiece not just because of its script, but because of the physical, chemical reality of the medium it was captured on.
