 Universal was so anxious to get a new Abbott and Costello film into  theatres that they sped up the production by bringing in a second  director, Erle C. Kenton (qv) (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)_ (qv). The rushed  production schedule made this the most expensive Abbott and Costello  film up to that time.
