Lemonade Joe, or the Horse Opera (Czech: Limonádový Joe aneb Koňská opera) is a 1964 Czechoslovak musical comedy film, directed by Oldřich Lipský and written by Jiří Brdečka, based on his novel and stage play. A parody of the American Western, the film centers on a clean-living, soft-drink-selling gunfighter who takes on a town full of whiskey-swilling cowboys. The name of the eponymous hero is a pun, since the Czech word for a soft drink, limonáda, can also be used figuratively in reference to a cheap, sentimental love-story.
