On David Fincher’s Mank, sound designer Ren Klyce was tasked with crafting a monaural soundtrack, similar to those heard in films of the ’30s and ’40s, engaging in a laborious, experimental process, in order to round out the world of one of the year’s most distinctive films.
Scripted by Fincher’s late father Jack, the director’s longtime passion project follows Herman J. Mankiewicz (Gary Oldman)—a washed up, alcoholic screenwriter from Hollywood’s Golden Age—as he endeavors to finish the screenplay for the iconic Citizen Kane.
The goal with Mank was to immerse viewers in its period world through the creation of visual and sonic ‘patinas,’ each working in concert with the other. While cinematographer Erik Messerschmidt shot the black-and-white film digitally, at extremely high resolution—allowing Fincher to degrade the image in post—Klyce would tinker with sonic degradation, tapping into all of the characteristics that gave early 20th century soundtracks their unique feel.
One of Fincher’s closest collaborators—who has worked with him on 10 features and two television series since 1995—Klyce had experimented only briefly with mono sound in the past, on a handful of Fincher films. “But we never did it with the conviction of, ‘This is the purpose,’” the sound designer notes, “‘because we want it to feel like it was made using the technology of the time.’”
Below, the seven-time Oscar nominee recalls his earliest conversations with Fincher about Mank, and the multifaceted process of fashioning its vintage sonic palette.
