Werner Herzog

Werner Herzog is a German director and actor born in 1942.
He is best known for Aguirre the wrath of god and Fitzcarraldo. his most notable films are (amongst many more):
-Signs of life
-Aguirre the wrath of god
-Heart of glass
-Fitzcarraldo
-The wild blue yonder
-Rescue dawn
-Grizzly Man
-Encouters at the end of the world
-The great ecstasy of woodcarver Steiner
-Lessons of Darkness

He did a great number of films both in fiction and documentaries. He also played in some films like Incident at loch ness (that i greatly recommend) or Julien donkey-boy.
The movies he makes generally depict madness in any form, and at the same time you are touched by the characters' madness as it is often harmless for others but destructive for themselves.
His documentaries are beautiful and are often made in a way that gives a mysterious feeling to what is filmed (through the images, the music and the director's monologue).
He recently did a remake of Abel Ferrara's Bad Lieutenant.

Werner Herzog is one of my favorite directors and i recommend all his films.
