Rita Hayworth's dancing partner in the number "On The Gay White Way" is choreographer Hermes Pan, Pan did the choreography of this film.
Studio head Darryl F. Zanuck originally wanted Carole Landis to play Sally Elliot, but she refused to dye her hair red and declared she'd play it as a blonde. The movie mogul promptly moved her to a secondary role and borrowed Rita Hayworth from Columbia, since Alice Faye, expecting her first daughter, could not take the part.
