The Andrews Sisters were brought in after filming wrapped and the final nightclub footage was edited in after the film's completion.
The runaway success of Buck Privates caused a stir in the upper ranks of Universal Pictures, which had already begun production on this film. The studio was enjoying its first solidly profitable year since it was acquired by new owners in 1936 and wanted to exploit Bud Abbott and Lou Costello as quickly as possible. The team's next assignment, In the Navy, was decided by the powers-that-be to be a better follow-up project, so production on this film was ordered halted. It resumed about 4 months later. In retrospect, the decision was logical but probably unnecessary, since the comedy duo was the hottest act in show business and would remain so throughout the war years.
