Italy’s Bandits of Orgosolo (1961), by Vittorio De Seta (not De Sica), is about Sardinian shepherds—a man and his younger brother—and their troubles with bandits, other shepherds, and uncompassionate policemen.  These two are persons of nature, working with and against nature—and against, to use a narrator’s word, “hostility.”  By hostility I mean the world:  everything from limited water to an unjust police official represents the world.

A classic art film, this, and a neorealistic one.  I managed to find it on YouTube.  I hope others will always be able to as well.
