Definitely one of those films that are famous for being notable in film history...not quite because it is particularly entertaining.  It is a film made in Iran that won the Venice Film Festival, all under the Shah's rule...so it was a significant achievement for third-world cinema.  The story is about a poof villager who is unhealthily obsessed with his cow.  When it dies while he is away, the villagers band together to protect this man from the awful truth.  When he does...he loses his mind and pretends that he, himself is the cow.  It is an odd movie that echoes a bit of Fellini's black and white work....but significance surely outweighs its appeal.
