North Sea Patrol is a remake of the 1927 film of the same name; both were adapted from Luck of the Navy, a stage play by Mrs. Clifford Mills. Using a few clips of actual battleships for versimilitude, the film concerns a covert plan by an unnamed enemy nation to invade the sacred shores of England. The spies disguise themselves as the household servants of an admiral, so it can be said with some assurance that this is one picture in which the butler did it. Coming to the rescue is the admiral's daughter (Judy Kelly) and her dashing young navy officer beau (Geoffrey Toone). Made just before the outbreak of WW2, North Sea Patrol was promoted as "up to date" entertainment, even though its source material was nearly twenty years old.
