One of Lubitsch's finest and most underrated films, Design for Living tells of three expatriate Americans in Paris-a struggling painter (Gary Cooper), an undiscovered playwright (Fredric March), and their self-appointed protectress (Miriam Hopkins). The threesome resolve to establish a platonic home in a garret, dedicated to the service of art, but the muse soon finds itself hard-pressed with both artists trying to get Miss Hopkins on a dusty couch and finally slipping into a blissful menage à trois that has their lady switching with casual promiscuity from one to the other. But there's trouble in this paradise, too, and when comradeship falls inevitably into jealousy, Miss Hopkins packs off to marry an incredibly stuffy businessman (played by the incomparable Edward Everett Horton) who uses her charm to grease financial transactions. Needless to say, this cynical fairy tale comes to a properly amoral conclusion.
