After Fred MacMurray and George Burns turned down the chance to make this film, producer Harlan Thompson offered it to Bob Hope and Bing Crosby. Thompson had seen the pair clowning on the Paramount lot, and it seemed to him that they got along well.
During a lunch break, Bob Hope threw a handful of the soap suds at Dorothy Lamour and soon Bing Crosby became involved. The fight ended when Lamour cornered Hope and Crosby and threw all she had at them. The director was not particularly pleased, because it would take hours to repair their hair, makeup, and clothing.
This was the first of the "Road" pictures that paired Bing Crosby and Bob Hope. However, Hope was given third billing behind Dorothy Lamour.
The soap suds used for Ace Lannigan's stain removing product Spot-O were special heavy duty suds created by the prop department to hold up under the hot lights.
