This film represents one of four movies made by Hollywood during the 1940s that were about or related to the US military's Dolittle Raid on Tokyo, Japan, during World War II. The four (the first three considered "fictionalized") are Destination Tokyo; The Purple Heart; this film; and Thirty Seconds Over Tokyo, the last being the most accurate and least fictionalized of the four.
