The Ducktators (1942)

Spoiler: A "Hitler" duckling emerges from the egg with a "Sieg Heil!"

The Ducktators is a 1942 Warner Bros. Looney Tunes directed by Norman McCabe. The short was released on August 1, 1942, and satirizes events of World War II.

A pair of farm ducks anticipate the hatching of their duckling from an unusually black-colored egg. A white duckling with a toothbrush mustache, Adolf Hitler, emerges from the egg and immediately shouts "Sieg Heil!" while giving the Nazi salute.

Hitler's adulthood is spent giving aggressive speeches toward the other ducks and geese. His only ally is a large black Neapolitan-accented goose, Benito Mussolini, who promotes his own warmongering rhetoric to a solitary chick who is forced to attend and applaud.

Hitler's stormtroopers surround the farm while a Dove of Peace, observing from above, weeps in anticipation of the upcoming violence. A peace conference is held between the ducks and geese, but the unstable Hitler puts the peace treaty through a paper shredder and instigates a furious brawl.

Meanwhile, an odd Japanese duck, Hideki Tojo, travels to the farm to support Hitler and Mussolini and "to make a silly Axis of himself". During his voyage across the sea, he absentmindedly plants a sign reading "Japanese Mandate Island" on a turtle's back.

When the turtle emerges, sees what has been placed on his shell and subsequently attacks Tojo, this 'Ducktator' vainly attempts to pass himself off as Chinese.

With their troops, Hitler, Mussolini and Tojo set out toward their planned conquest of the farm. The Dove attempts to reason with them, but they ignore and trample him. The Dove violently retaliates and, with the aid of other animals - including a rabbit that is a send-up of Jerry Colonna (possibly a caricature of Joseph Stalin).

The Ducktators are seen running as a Minuteman emerges from a poster that says "For Victory, Buy United States Victory Bonds" and begins firing his musket. The Dove is then seen relating the tale to his two children, Peace and Quiet, while proudly displaying the battered heads of his enemies as trophies mounted above his fireplace.

A final message invites the audience to express their patriotism by buying state bonds. ~ Wikipedia
