Boasting Tony Martin and Rita Hayworth and bandleader Andre Kostelanitz as its leading players, its surprising that Music in My Heart isnt better than it is. Martin plays European-born actor Robert Gregory, who while rehearsing for a Broadway musical falls in love with chorine Patricia OMalley (Rita Hayworth). She likewise falls in love with him, even though shes 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 Ritas kid sister. Of the films six songs, Its a Blue World is the singular highlight. ~ Hal Erickson, All Movie Guide
