Synopsis by Hal Erickson
This easygoing service comedy stars Donald Keith in the title role. A tough topkick, Mulligan intends to make a "real man" out of enlistee Mickey Neilan (Wesley Barry), a former vaudevillian. After the standard basic-training gags, Mulligan and Neilan are shipped to France, where they are sent out to capture a nest of spies. Instead, our heroes get captured themselves and are shipped to Berlin, where they manage to escape and emerge from the experience as war heroes. The film's romantic angle concerns Neilan's romance with his fickle vaudeville partner (Lila Lee). Top Sergeant Mulligan was designed to allow former child star Wesley "Freckles" Barry to segue into adult roles; Barry later forsook acting to become a busy assistant director and producer.
