Puss in Boots (1969) IMDb
A cat expatriates himself to France(ish) after he spares a mouse. Three assassins from his country follow him to carry out his death sentence. Largely unhindered by this, the fugitive gets involved in the case of an unfairly treated farm boy who is almost as vegetative as the princess of the realm. Lucifer interferes.
Fairytale comedy based on Perrault’s reinterpretation of Grimm. Historically significant but very Disneyesque blend of moral polarization, anthropomorphic animals, musical numbers and silly audio cues. Miyazaki provided some ideas.
