Casting an envious eye towards the huge box-office take of Columbia's Grace Moore vehicles, Republic hoped to strike gold in a similar fashion by fashioning a screen property for Kansas-born Metropolitan Opera diva Marion Talley. As it turned out, Follow Your Heart was Talley's first and last film, but Republic at least deserved a gold star for effort. The star is cast as Marian Forrester, the daughter of onetime opera star Madame Bovard (Henrietta Crossman). Recalling the many heartbreaks and disappointments attending her own stardom, Mme. Bovard refuses to allow Marian to pursue a singing career. But with the surreptitious help of handsome Michael Williams (Michael Bartlett, another real-life singer) and bumbling but lovable voice teacher Henri Forrester (Nigel Bruce), Marian makes her Met debut, and her mother gracefully bows to the inevitable. Though there's plenty of "straight" singing throughout Follow Your Heart, the film's highlight is a burlesque of the "Sextet" from Lucia di Lammermoor.
