Le fantôme de la liberté

One of Buñuel's greatest films. Scene after scene arguments are used as beautiful excuses to subvert reality and attack established and hypocritical institutions with acute humor and surrealist means. If you have a taste for surrealism and absurd humor (i.e. Monty Python, Marx Bros., etc.) this movie cannot be recommended enough.

One small correction: the sniper is not sentenced to death but to capital punishment which results in something altogether different from death (and far more sarcastic).
