Movie Description

Heart of Glass is a 1976 German film directed and produced by Werner Herzog, set in 18th century Bavaria. The film was written by Herzog, based partly on a story by Herbert Achternbusch. The main character is Hias, based on the legendary Bavarian prophet Mühlhiasl.

During shooting, almost all of the actors performed while under hypnosis. Every actor in every scene was hypnotized, with the exception of the character Hias and the professional glassblowers who appear in the film. The hypnotized actors give very strange performances, which Herzog intended to suggest the trance-like state of the townspeople in the story. Herzog provided the actors with most of their dialogue, memorised during hypnosis. However, many of the hypnotised actors' gestures and movements occurred spontaneously during filming.
