After the film was completed, Universal wanted to rename it "Abbott and Costello in the Stunt Men", because they did not consider the "Keystone Kops" to be relevant anymore. However, in October, 1954, the studio relented and agreed to use the "Keystone Kops" name.

Edison's Black Maria studio in West Orange, NJ, and finds he has been duped into buying it by Fred Clark, his new studio sign gets thrown into a pile representing the others who were defrauded into thinking they were buying a working movie studio.
