Picnic on the Grass is a 1959 French comedy film written and directed by Jean Renoir, starring Paul Meurisse, Fernand Sardou and Catherine Rouvel. It is known in the United Kingdom by its original title or in translation as Lunch on the Grass. A satire on contemporary science and politics, it revolves around a prominent biologist and politician who wants to replace sex with artificial insemination, but begins to reconsider when a picnic he organizes is interrupted by the forces of nature. The film brings up issues of modernity, human reproduction, youth and European integration. It ridicules rationalist idealism and celebrates a type of materialism it associates with classical mythology and ancient Greek philosophy.
