When the Cat Comes is one of the more quietly subversive films of the Czechoslovak New Wave, and its visual flair, storybook fantasy and absurd humour make it fun for viewers of all ages. The film won the Cannes Special Jury Prize in 1963 thanks to the winning combination of director Vojtěch Jasný, writer Jirí Brdecka—known for his collaborations with animator Jirí Trnka—and lead actor Jan Werich, writing his own dialogue in the dual role of Comrade Oliva and the Magician.
