Grigorii Aleksandrov's musical comedy films, created with composer Isaak Dunaevskii, were the most popular Russian cinema of the 1930s-1940s. This study presents the untold history of the films, situating them in the Stalin era, and suggesting new interpretations of individual films. The book challenges conventional political interpretations, looking instead at how the films inscribed the Stalin's myths into the national consciousness, reproducing the dominant ideology, while hiding it beneath layers of humour. Simultaneously, Salys unearths the methods of composer Dunaevskii: the interplay of music and lyrics with narrative and the encoding of socialist values through fairytale-folklore and gender, providing audiences with entertainment, escape from the hardships of the everyday and hope for a better life. "The Musical Comedy Films of Grigorii Aleksandrov" asks why these films are considered classics both in Russia and the West, and how Aleksandrov became a cultural icon, indelibly influencing modern Russian cinema.
