Because the Baron of Chanterelle wants to preserve his family line, he forces his timid nephew Lancelot to choose one of the village maidens to wed. Lancelot flees to a monastery to escape the forty eager maidens. When the gluttonous monks discover that the Baron is offering a large sum for the marriage, they suggest Lancelot marry a mechanical doll instead.
I absolutely love how this was put on as a mixture between a play and a film. Some of the sets (such as inside the castle) seem quite elaborate, while other things (the trees and horses) smack of a high school production. But not in a bad way -- there is a certain charm to how this story unfolded. Add to that the wild hair and outfit of the puppet master (a precursor to Willy Wonda) and you have a great looking film.
Something could be said about the interaction between people and robots, and at what point are robots so lifelike that the line between human and non-human is all too fuzzy. But this is a light-hearted film and I will not get too serious here.
