The Devil With Hitler, 1942 produced by Hal Roach Studios (Little Rascals/Our Gang) Hitler, Mussolini & "Suki Yaki" (i'm dying!) are featured in a Three Stooges style slapstick comedy. These three should still be a slapstick trio, i would go see their movies like "The Axis Oafs vs. the Invisible Man & Frankenstein" in a second.
Here are some screen shots.
But wait, there's a sequel!
