Watch Explosion! (1939) Online

"Around the time he made such remarkably ambivalent war films as Mud and Soldiers and Five Scouts, Tasaka directed this 'home front' comedy-drama which is too bizarre to be serious propaganda. [The plot revolves around a public contribution campaign to buy airplanes.] The mayor's aviator son promises to fly over the village in salute, and much of the narrative concerns the preparations for this great event. Tasaka throws in a few songs, some village humor and satire, and tremendous camera mobility, finally wringing every possible effect from his climax." John Gillett, British Film Institute
