Notable for being the last film appearance of the great pianist and conductor Jose Iturbi and the first movie of operatic tenor Mario Lanza, the story casts Lanza as a singing truck driver discovered by an opera singer played by Kathryn Grayson. Their love story is just a premise for some fine music, including selections from Verdi, Chopin, Tchaikovsky, and Jerome Kern. This is the film that made a matinee idol out of Lanza and launched a turbulent career that ended seven films later when he died at age 38.
