This film, presented as a documentary drama, functions more like an examination of how Japan successfully surprised the American military on that pivotal day. A conversation between fictional characters—"Uncle Sam," voiced by Walter Huston, and "Mr. C," portrayed by Harry Davenport—serves as the narration. Initially, they praise Hawaii’s diverse population and its economic contributions through industries like sugar cane and pineapples. However, their tone gradually shifts to a more unsettling perspective regarding the roughly 157,000 residents of Japanese descent, representing about one-third of the island's inhabitants. The film raises questions: Were these individuals simply proud of their heritage and Shinto beliefs, or were some involved in a clandestine network sharing military secrets with Japan through its consulate—which is notably positioned near the Nazi diplomatic representative? These dramatic sequences, based on speculation and broad assumptions, don’t significantly enhance the overall presentation. Nevertheless, certain editing choices are quite impactful, particularly those depicting the attack on Pearl Harbor. The film incorporates approximately five minutes of authentic footage, interspersed with recreated action scenes, offering a vivid portrayal of the sustained assault on the facility, its ships, and nearby airbases as they were unexpectedly subjected to an onslaught from over 200 aircraft. By the end, one might believe that nothing remained operational or capable of flight, and it’s likely this film effectively stirred up anti-Japanese feelings during wartime in 1943. While other films offer superior accounts of December 7th, few utilize such a vast collection of original photography as skillfully.
