Bud Abbott and Lou Costello were engaged in an acrimonious contract dispute with Universal Pictures during the making of this film. As a result, they refused to do re-shoots and every day, at exactly 4:00 p.m., whether they were in the middle of a scene or in the middle of a line, they would cease working and go home.
Universal was so anxious to get a new Bud Abbott and Lou Costello film into theaters that they sped up the production by bringing in a second director, Erle C. Kenton (who directed at least two production numbers, uncredited) and created the climatic chase sequence using footage from Never Give a Sucker an Even Break (1941). The rushed production schedule made this the most expensive Abbott and Costello film up to that time.
Leading lady Marion Hutton had been the female singer with Glenn Miller's band and was the sister of Paramount superstar Betty Hutton. A third Hutton sister, June, also sang on records and later married Frank Sinatra's arranger, Axel Stordahl.
