Munro is a 1960 Czechoslovak-American animated short film directed by Gene Deitch, written by Jules Feiffer, and produced by William L. Snyder.
[4] The title character is a rebellious little boy who is accidentally drafted into the United States Army.
Eventually, the harshness of army life makes Munro cry, which causes the general to realize that he really is a little boy.
He is discharged and becomes a hero...and whenever he misbehaves, Munro is reminded of his stint in the army.
And so Munro tells this savage story but tells it entertainingly and sweetly and builds it up and gets the reader stressed, and as you read it, and particularly when you see the film, you feel your stomach knot up because of the obvious abuse and ignorance of authority.
