Though the bulk of the footage seen in the documentary was from Heinzerling’s final year of filming (he shot the film as well as produced and directed it), he followed—and filmed—the couple for five years. “So much of their personalities came out of these everyday things, whether it was making art or making dinner,” he told Indiewire. “Everything had this real sense of purpose and character, so as a cinematographer it was a dream project. As a character study, it was a project I knew had a lot of potential, but I had to wait for things to happen, and that's really why it took five years, the time for a story and narrative to develop and for Noriko to open up and for the truth and vulnerability and deeper layers of her character to reveal themselves in front of the camera.”
