Despite the title, most of the film fortunately takes place above water as Larry Parks dons headphones as the radio operator who learns of the Japanese attack on Pearl Harbor fresh from sinking a pleasure cruiser and strafing the lifeboat containing the survivors.
The late Bob Baker once described the submarine picture as "what must be every cameraman's number one headache", but Franz Planer (treating water in Hollywood between 'Leibelei' and 'Letter from an Unknown Woman') undaunted helps deliver a good-looking little potboiler to which the frequent use of stock footage and obvious use of models lends a certain goofy charm. (As usual the Japs demonstrate their complete unconcern for all human life - including their own - when one of their airman pays for failure by saluting smartly and promptly jumping off the side of the submarine into the ocean.)
