Though its purely propagandastic aspects are never far from surface, Destination Tokyo must rank as one of the most intelligent and objective of wartime thrillers. Cary Grant is a tower of strength as Captain Cassidy, skipper of an American submarine bound for Tokyo harbor. Its mission: to allow a Navy meterologist to survey Japanese weather conditions, in preparation for a major Allied assault. Many of the individual incidents in Delmar Daves script are based on fact, notably an episode in which a pharmacists mate is called upon to perform an emergency appendectomy. Admittedly, some of the secondary characters are WWII stereotypes, but theyre never played that way. Particularly good isDane Clark, in his first important screen role; also registering well as a radio man is John Forsythe, in his first screen role ever. From the subs embarkation in San Francisco to its climactic retreat from Japan, theres not a single solitary dull moment in the 135 minutes of Destination Tokyo. ~ Hal Erickson, All Movie Guide
