Grasshoppers

An animated short by Bruno Bozzetto which condenses the whole of human civilization into 9 minutes, focusing primarily on the human race's predilection for warfare and the vanity of war. It was an Oscar Nominee for Best Animated Short in 1991.
Each piece of history is presented as a simple vignette, usually depicting a few simply-drawn characters arguing and making war, over and over again. Generally, a single figure is meant to stand in for an entire group (i.e., a single Caesar-like caricature for the entire line of Roman Emperors). There is very little spoken dialogue; instead, most of the cartoon is accompanied by a bouncy piano-driven score, which frequently changes style to suit the particular historical era. However, the score is all based around a single simple theme, to which it frequently returns in between vignettes.
