One of the last films to feature prostitution as a major theme before the rigid enforcement of the Hays Code.
Carole Lombard and the president of Columbia Pictures, Harry Cohn, met for the first time right before production on this film began. Cohn, famous for his opinionated and profanity-laced comments, told Lombard that her hair was too white and made her look like a whore. Not missing a beat, Lombard responded, "if anyone would know a whore it would be you." After this rocky start, the two developed a mutual respect that lasted the rest of their careers.
At one point, Frank tells Jimmy, "You're no Clark Gable." Coincidentally, Lombard and Gable would later marry in real life.
Although real Yellow Cabs were used, they were renamed "Yellow Taxi Corp." and "Circle Cab Co." The partial overlays on the sides of the cars are clearly visible.
