Serenade represented the return to the screen of international favorite Lillian Harvey after an absence of two years. Based loosely on the life of composer Franz Schubert, the film casts Bernard Lancret as Schubert, Harvey as his dancer sweetheart, and Louis Jouvet as a possessive Baron who has his own designs on our heroine.
