FILM: Aguirre, The Wrath of God

This was the first in a line of Klaus Kinski films directed by Werner Herzog. Kinski, possibly mad himself, is brilliant at playing the insane.
This is a slow moving film about a group of Spanish soldiers (though the film is in German) who are searching for El Dorado against all odds.
They befall many troubles along the way, a lot of them due to the madness of Aguirre, and the following he gathers when threatening violence.
From starvation and sickness, the group of soldiers all die, and the film ends with a mad Aguirre stumbling around, talking to himself.
With hints of incest, and clear madness, and a lot of death, this film is dark in a calm sort of way.
It's a 'stick at it' kind of film - it's an exploration into madness and leaders, not plot.
If you're interested in discovering arty foreign films, this is a good start.
