Coming together under Capra's direction and spurred on by General Marshall, this film rises above the typical propaganda films that Hollywood released after Pearl Harbor. Instead of simply praising American military strength, it employs historical footage to systematically portray the Axis powers in a negative light. While there isn’t much direct imagery of the Emperor, the filmmakers effectively depict Japan's expansion through locations like Korea, Manchuria, and Shanghai. Mussolini and Hitler offer richer material for the film-makers, who utilize both film clips and animated maps to illustrate Italy's actions in Ethiopia and Germany's moves in Austria and Czechoslovakia. By 1942, with Europe largely pitted against Great Britain, and Japan seemingly unstoppable in the Far East, the movie presents a strategy that demonstrates how a plan for global domination could realistically arise from these separate conflicts. The narration is more educational than overly patriotic, and after its roughly one-hour length, I felt like I’d gained knowledge rather than just been brainwashed; especially seeing Hitler's speeches, which really showed his grandiose nature. A lot of the information isn’t groundbreaking, but it’s still a worthwhile viewing experience.
