Part spy film, part screwball satire, Vidor’s 1940 film finds Clark Gable playing Mac Thompson, a USSR-based American journalist who pseudonymously pens scathing dispatches from the Soviet Union on behalf of the anticommunist West. When Mac’s cover is blown, he is lured into a blackmail plot wherein he must marry a streetcar conductor (Hedy Lamarr) and take her away from the USSR so that she can spread the gospel of Marxism-Leninism—but, of course, this plan goes sideways, to hilarious effect. Something of a companion film to Ernst Lubitsch’s Ninotchka (1939), Comrade X prophetically anticipated the invasion of Russia and Ukraine by Germany less than a year after its release.
