Heart of Glass (film)

Heart of Glass German Herz aus Glas 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 Mhlhiasl.

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 trancelike 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.The majority of the film was shot in Bavaria, just a few miles from where Herzog was raised in the remote village of Sachrang nestled in the Chiemgau Alps, and also at a nearby village in Switzerland. Other brief shots of landscape scenes were filmed in various locations around the world that Herzog scouted out, including Yellowstone National Park. The conclusion of the film was shot on the Skellig Islands. ........
