 Filmed covertly on location in parts of Denver, Colorado, and El  Paso, Texas. El Pasos red light district stood in for Storyville,  the famous red light district in New Orleans. Several of the women  of the El Paso district discovered that they had ended up in the  film, and filed a lawsuit against writer/producer Samuel H. London.  Their complaints were not over any invasion of privacy, but over  misrepresentation of which city they were working in.
