Submarine I-57 Will Not Surrender (潜水艦イ-57降伏せず, Sensuikan I-57 kofuku sezu) is a 1959 Japanese war film directed by Shūe Matsubayashi, with special effects by Eiji Tsuburaya, the wizard himself.
During World War II, the commanding officer of a sub reluctantly takes on board two Western diplomats to take them to the Canaries and arrange an armistice. When they get there, Japan has surrendered, but the sub's crew do not know that since its radio has failed. It sends its passengers ashore to go out to face a final battle.
