All though nowhere on Wikipedia it says that the movie Playtime by French filmmaker Jacques Tati refers to Constant's New Babylon project, the film poster does bear a close resemblance to several of Constant's constructions and drawings of New Babylon.
Where Constant sees an optimistic nomadic future in automation Playtime's main charachter Mr. Hulot, played by Tati himself, and a group of American tourists get lost in a fururistic Paris.
Hulot, and a group of American tourists attempt to navigate a futuristic Paris constructed of straight lines, modernist glass and steel high-rise buildings, multi-lane roadways, and cold, artificial furnishings. In this environment, only the irrepressible nonconformity of human nature and an occasional appreciation for the good old days breathe life into an otherwise sterile urban lifestyle. Modern industrial technologies, accepted as necessary by society, are represented by Tati as obstructions to daily life and an interference to natural human interaction (Wikipedia)
