The featured song "Please Don't Say No (Say Maybe)" was recorded by numerous singers in the late 1940s.
Producer Joe Pasternak often took license in merging fact with fiction in his casting. For example, Jose Iturbi played himself as a single man in Three Daring Daughters (1948) after playing himself as a married man with myriad children just two years earlier in Holiday in Mexico (1946). In a similar vein, in Thrill of a Romance (1945), Tommy Dorsey introduces his daughter, Susan Dorsey, who takes the stage to perform the "Hungarian Rhapsody" on piano (which transforms into "The Guy With the Slide Trombone"). In fact, Dorsey did not have a daughter named Susan. She was a fictional character portrayed by teen actress Helene Stanley, who frequently appeared in Disney films of the period.
This film marked the film debut of Metropolitan Opera star Lauritz Melchior, one of several classical artists lured to MGM by producer Joe Pasternak in the 1940s. Melchior would ultimately appear in three other MGM musicals: Two Sisters from Boston (1946), This Time for Keeps (1947), and Luxury Liner (1948).
