After Hollywood or Bust, this was to have been the next film for Jerry Lewis and Dean Martin. Martin did not want to be seen on screen in a police uniform and refused to do the film. Their partnership soon ended, so this film was Lewis' first solo effort. The part originally meant for Martin was given to Darren McGavin.
One of the police officers is named "Sgt. Levitch". Jerry Lewis' real name is Joseph Levitch.
