Although they had previously appeared together in That Midnight Kiss, Kathryn Grayson and Mario Lanza did not get along while making this film. While shooting the love duet scene from "Madame Butterfly," Grayson recalled that Lanza kept trying to French kiss her, which was made even more unpleasant by the fact that he kept eating garlic before shooting. To counter this, Grayson had costume designer Helen Rose sew pieces of brass inside her glove. Each time Lanza attempted to French kiss her, Grayson would smack him in the face with her brass-loaded glove. One of these smacks was included in the movie.
