Each of the long takes was shot on an entire 1000-foot reel of 35mm film.
The extreme zoom in the first scene was achieved with an Angenieux Super Tele 40x zoom lens (30mm - 1200mm).
Shot and projected in theatres exclusively on 35mm film.
The maximum possible length of a take under the filming conditions was 22 minutes, 21 seconds. Accordingly, there are several references to the number 22--the boxing match ends at 22 rounds, Sampson says Janet has been too old for the dating scene since she was 22, and the title card appears at 22:22.
John Hawkes and Robert Forster also play a troubled private investigator and a wealthy man with family problems respectively in Small Town Crime (2017).
