Heart of Glass (1976)

Directed by Werner Herzog

A small Bavarian village is renowned for its "Ruby Glass" glass blowing works. When the foreman of the works dies suddenly without revealing the secret of the Ruby Glass, the town slides into a deep depression, and the owner of the glassworks becomes obssessed with the lost secret.

Most of Herzog’s best films do nothing less than take challenge the hubris inherent in the concept of civilized life, and Heart of Glass is no exception.
