I think Cagney is a great actor with a unique style and personality. Anything he appears in is worth watching. Blood on the Sun was directed by Frank Lloyd, a Hollywood veteran who’d been making pictures since the silent era. It’s a wartime potboiler with a dubious MacGuffin; the Tanaka Memorial, an alleged strategic document from 1927 in which Prime Minister Baron Tanaka Giichi created for Emperor Showa a strategy to take over the world. It is believed by many historians to have been a forgery. In the ’30s and ’40s, however, the document was widely accepted as true. It was mentioned in Frank Capra’s agitprop documentary series, Why We Fight, and translations were published in Chinese and American periodicals. Of course, one reason why it was widely regarded to be an actual document is because Japan’s actions so closely mirrored the strategy that the Tanaka Memorial outlined; the conquest of Manchuria and Mongolia, followed by the invasion of China, the establishment of bases in the Pacific, and the eventual conquest of the United States. So although General MacArthur’s armies were unable to uncover any original Japanese-language versions of the Tanaka plan after World War II, perhaps its authenticity is beside the point.
