Cheech & Chong's The Corsican Brothers

As the story unfolds, our two heroes, down-on-their-luck rock musicians (Cheech Marin and Tommy Chong, Up In Smoke) wandering the streets of France after a disastrous performance (the locals have actually paid them to stop performing), happen upon a gypsy storyteller. The gypsy regales them with stories of the noble Corsican Brothers (also played by Cheech and Chong) who plot to take down the evil nobleman Fuckaire, portrayed with scenery-chewing glee by Roy Dotrice (Amadeus).
