The Corn Is in Danger(1945)

Kornet er i fare is a Danish documentary short warning farmers about destructive corn weevils, released under Nazi occupation. Blending live action with animation and humorous narration, it depicts the pests as invaders in a military-style battle and advises preventive measures. While officially Nazi-approved, the film was widely interpreted—and perhaps intended—as an allegory of Danish resistance against the occupiers. It premiered on April 1, 1945.
