Boasting Tony Martin and Rita Hayworth and bandleader Andre Kostelanitz as its leading players, it's surprising that Music in My Heart isn't better than it is. Martin plays European-born actor Robert Gregory, who while rehearsing for a Broadway musical falls in love with chorine Patricia O'Malley (Rita Hayworth). She likewise falls in love with him, even though she's scheduled to marry millionaire Charles Gardner (Alan Mowbray). The relationship is endangered when Gregory faces deportation to his own country, but baton-wieldig Kostelanitz comes to the rescue by making Gregory a radio singing sensation. Talented child actress Edith Fellows, who in previous films had been given top billing over Rita Hayworth, is somewhat wasted in the role of Rita's kid sister. Of the film's six songs, "It's a Blue World" is the singular highlight.
