The French film musical is remarkable for its breadth and variety since the 1930s; although it flirts with the Hollywood musical in the 1930s and again in the 1950s, it has very distinctive forms rooted in the traditions of French chanson. Defining it broadly as films attracting audiences principally because of musical performances, often by well-known singers, Phil Powrie and Marie Cadalanu show how the genre absorbs two very different traditions with the advent of sound: European operetta and French chanson inflected by American jazz (1930-1950). As the genre matures, operetta develops into big-budget spectaculars with popular tenors, and revue films also showcase major singers in this period (1940-1960). Both sub-genres collapse with the advent of rock n roll, leading to a period of experimentation during the New Wave (1960-1990). The contemporary period since 1995 renews the genre, returning nostalgically both to the genre's origins in the 1930s, and to the musicals of Jacques Demy, but also hybridising with other genres, such as the biopic and the documentary.
