78/52 (2017) on Netflix

Plot summary

Marion Crane is at the Bates Motel when a killer comes for her in the shower, a murder that audiences have watched for decades. That sequence from Psycho, the 1960 horror film, is what the documentary examines. The scene has a claim to being the most famous murder in the movies, and its makers count 78 camera setups and 52 cuts in it, which gives the piece its title. Filmmakers and actors sit down to talk through how the sequence was put together, from the framing of each shot to the rhythm of the cutting, and to weigh the place the scene has come to hold in movie culture.
