I caught this on TCM, it is a completely captivating and delightful experience for all ages, so many layers in this story. Cannot recommend it enough for its period charm and generally kookiness.
However, the cast list here on IMDB is a mess due to faulty translations. "Dessen Frau" means "His Wife", and refers to Baron Chanterelle (chanterelles are a group of mushrooms, much eaten in Germany in late summer/autumn.) Similarly, "His Daughter" (Ossi, or The Doll) again refers to the Baron as her father. "The Briar" (!) should, I think, be The Friar; only in the film he is in fact the Abbot of the monastery, not merely a Brother. Wikipedia gets it all correct on its page about this film.
