One Hundred Men and a Girl is a 1937 American musical comedy film directed by Henry Koster and starring Deanna Durbin and the maestro Leopold Stokowski. Written by Charles Kenyon, Bruce Manning, and James Mulhauser from a story by Hanns Kräly, the film is about the daughter of a struggling musician who forms a symphony orchestra consisting of his unemployed friends. Through persistence, charm, and a few misunderstandings, they are able to get famed conductor Leopold Stokowski to lead them in a concert, which leads to a radio contract. One Hundred Men and a Girl was the first of two motion pictures featuring Leopold Stokowski, and is also one of the films for which Durbin is best remembered as an actress and a singer.
