The fairy-tale allegory "Až prijde kocour" ("The Cassandra Cat") was shot by Vojtech Jasný after making a name for himself with the anthology film Touha ("Desire", 1958). Jirí Brdecka and Jan Werich collaborated with Jasný on the screenplay. Werich also acted in the film, portraying both the main narrator and a traveling magician who puts on a show in the small Czech town. The magician is accompanied by the performer and a magical cat with sunglasses. When the sunglasses are removed, the cat’s vision is able to reveal the true nature of people. Lovers turn red, thieves turn gray, traitors turn yellow… With its combination of colorful special effects and fantasy story with moralistic undertones, the film enchanted the jury in Cannes, where Jasný won the Special Jury Prize.
