The War Department Motion Picture Board of Review initially rejected the film for release because the story misrepresented the Army Intelligence Division as engaging in espionage. After studio revisions, the film was still refused approval because the Army said that Kay Kyser's character would never be called into the Intelligence Service without qualifications and training. Producer Harold Lloyd suggested that Kyser get the orders from a mixup of names, but that revision was still rejected because the Army did not want a commissioned officer to be made to be the object of ridicule. A further revision having Kyser decommissioned and entering the Intelligence Service as a civilian was finally approved by the War Department. Additional scenes were filmed in late February 1942 to make the changes in the film.
Warren Hymer (Jessie's Taxi Driver), Matt Moore (Desk Sergeant) and Ralph Sanford (Theater Policeman) are in studio records/casting call lists for their parts, but were not seen in the movie. Pre-production news items added Harold Lloyd (as a Recuit) and Ginny Simms in the cast, but they did not appear in the movie either.
Teddy Hart, the very diminutive brother of the great lyricist Lorenz Hart (Rodgers & Hart), has a tiny role as the complaining solider in the early Army training base sequences. Teddy had the lead in the Broadway production of his brother's Musical "The Boys From Syracuse" but never ever equaled his brother's success.
