Victor Mature was known within the movie community for having a sense of humor about his lack of acting, singing and dancing talents and supposedly once responded to being denied membership in a high-class social club for being an actor, by declaring: "I'm not an actor...and I've made 37 movies that prove it!"
Sally Elliott (played by Rita Hayworth) is a fictional character. In real life, the "Sally" in Paul Dresser's song, "My Gal Sal," was probably Sally Walker, an Evansville, Indiana brothel madam with whom Dresser had a long-term affair.
Hayworth suffered a badly bruised nose when she collided with dance director Hermès Pan during rehearsals, reported Hollywood columnist Erskine Johnson in January 1942. (Newspaper Enterprise Association, "Erskine Johnson's Hollywood", The San Bernardino Daily Sun, San Bernardino, California, Sunday 11 January 1942, Volume 48, page 16.)
The establishing shot for New York City is the sign post for W. 28th St. and 6th Ave. For those too young to remember, that indicates that Dresser has arrived at the famous Tin Pan Alley, which was located on W. 28th St between 5th and 6th avenues.
