The actress Elisabeth Bergner plays Gaby, a woman torn between her husband and her lover. Bergner’s congenial portrayal and Czinner’s direction led the film to worldwide success. Der träumende Mund continues to fascinate audiences to this day, as a master- ful study of the Weimar spirit and as a catalog of the aesthetic norms of the 1920s.
