This Gallic take on the feel-good chestnut about the inspirational power of music follows a nebbishy new housemaster at a strict school for troubled youth, ominously named Bottom of the Pond. The success of the timid yet musically subversive teacher is assured from the outset, since the film's 40-years-later wraparound establishes that one of his pupils will become a world-renowned maestro—allowing the audience to relax and enjoy the inevitable victory of humor and harmony over rigidity and repression. The excellent cast in Christophe Barratier's loose remake of a 1945 Jean Dreville film ensures that the predictable, nostalgic ride remains enjoyable throughout. In French with subtitles. PG-13, 97 min.
