Un mondo di marionette (1980) is Director Ingmar Bergman's only movie shot in the German language. L'uovo del serpente (1977) was shot in Germany, too, but mostly in English.
Inspired by the movie project "Love with No Lovers", Writer, Producer, and Director Bergman tried to realize for many years. With the story of Peter and Katarina in the center, it instead became a piece of television drama.
