But what makes Disney wish this would quietly go away is the portrayal of Donald Duck as the loyal Nazi (during what later turns out to be a dream sequence).
"Der Fuhrer's Face" was just one in a line of seven Pro-US and Pro-Army shorts done by Disney at the time". Also, they weren't the only ones getting in on the propaganda train, seeing as Popeye did it too (with the subtle title, "You're a Sap, Mr. Jap!"), as well as everyone from Daffy Duck to Superman, so yeah, this was pretty common for the time.
It won the 1943 Academy Award for Animated Short Film and was voted #22 of the 50 Greatest Cartoons of all time in 1994. The shorts effectively launched Donald Duck from sidekick to superstar, starring in 100 animated shorts between 1943-1961. Still, Disney has worked hard to keep this one out of circulation. We guess Donald enthusiastically doing the Heil Hitler at 1:56 is the sort of thing that could be taken out of context.
