When Willie (Lou Costello) goes to the theatre, the pretty lady in the box office is actually Costello's real-life daughter Carole Costello. She was made up to look much older than her real age.
Three members of the original Keystone Kops of silent films worked on the picture: Hank Mann, Harold Goodwin and Heinie Conklin. This is the 13th "Keystone Kops" film.
After the film was completed, "Universal-International" 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.
After arriving in Hollywood, Willie is put to work as a stuntman. Lou Costello's first job in Hollywood was also as a stuntman.
The chase at the end was sold by Castle Films in 8 and 16mm film under the title "Have Badge, Will Chase."
