Canadian Norman McLaren's pacifist satire during the Korean War. Music was done by painting "waves" directly onto the film stock's "soundtrack" strip. Much of his early animation was done the same way (painted frame by frame). Check him out on Youtube. He won an award in 1953 for best Short Form Documentary for this piece. The scenes with the wives and babies was originally pulled by the government which provided the grant for the film and was only reinstated in the 70s. Twisted, poignant, and mildly disturbing.
