Bud Abbott and Lou Costello were under contract to Universal Pictures, and their films were so successful that MGM signed a three-film contract with them to take advantage of a clause in their Universal contract that allowed them to do one film a year for another company. This was the first one; Lost in a Harem (1944) and Bud Abbott and Lou Costello in Hollywood (1945) were the others. However, each of the films was less successful than the previous one, and MGM canceled its agreement with Universal after the third film.

Only 2 songs were used in this 1942 movie, and the screenplay bears no resemblance to the plot of the 1929 version. In fact, the SAB designated the 1942 version as an original story.
