Even though it is for only a few seconds, we hear Rita Hayworth sing with her own voice. This is believed to be the only time in a film when this happens.
Ann Sheridan was originally cast as Virginia Brush but became involved in an acrimonious salary dispute with Warner Brothers. The studio borrowed Rita Hayworth from Columbia, whose career was foundering with clinkers like Blondie on a Budget (1940), and "The Strawberry Blonde" became a big boost to her career. Jack L. Warner liked her work so much that he immediately used her again in another romantic comedy, Affectionately Yours (1941).
