Meet John Doughboy (1941)

"Porky Pig" is quite literally drafted, very briefly, into this wartime morale-booster that plans to present us with some top secret newsreel. It starts with quite a fun "Daffy Duck" style RKO emitting logo, but thereafter it descends into a rather clumsily put together animation extolling the might of the US military. There's a lightly comedic basis underpinning it on occasion - a "Spitfire" that actually does, but the jokes are fairly poor and the stereotypes wear a little thin after a few minutes. Sure, in 1941 it had a job to do - and I suppose it does it well enough, but many years later it's near the bottom of the pile of propaganda efforts, sorry.
