a role in Hour of the Wolf, having seen earlier versions of the Cannibals screenplay and deciding a frightening film would be fun. Naima Wifstrand's part as the lady with the hat was her last film role. Filming Principal photography took place at Hovs Hallar and Råsunda Studios in Stockholm, and on the island of Fårö. Hovs Hallar's coast was particularly used for exterior shots. Shooting lasted from 23 May to 23 November 1966. Ullmann said she had little understanding of the subject matter during production, but recognized Bergman's traits in von Sydow's character. During shooting, including of her monologue scene, she became frightened imagining Bergman could degenerate like the character. She said there were no rehearsals or discussion of the film's meaning.

Themes and interpretations Johan has been interpreted as "Bergman's alter ego". Professor Frank Gado interprets the film as the "story of an artist's disintegration" (also arguing it reflects "Bergman's own unraveling", and criticizing the film). Author Dan Williams similarly reads it as a "story of the
