From NetFlix:

In the mid-16th century, after annihilating the Incan empire, Gonzalo Pizarro
leads his army of conquistadors over the Andes in search of the fabled City of
Gold, El Dorado. As Pizarro’s soldiers battle starvation, Indians, the forces of
nature and each other, Don Lope de Aguirre (Klaus Kinski), ‘The Wrath of God,’
is consumed with visions of conquering all South America and leads his own army
on a doomed quest into oblivion.

All three film catalogs rave about this film. In fact it is one of a kind, slow, and mesmerizing.

First some history: Pizarro sends a “small” task force to continue down th Amazon to find the City of Gold. The commander Pedro de Ursua and his aide, Lope de Aguirre, take soldiers (always in metal battle gear), one priest, Inca slaves, cannon, horses, and two noble women carried in a covered transport box down the mountain and eventually on rafts in the Amazon. Aguirre murders Ursua in an act of mutiny and forces the others, by force of his homocidal mania, to continue on to find the City of Gold. Much of this we know from the priest’s diary. The end is conjecture.

The marvel is that these poor actors had to live and suffer just as the historical figures did. Werner Herzog, the megalomaniacal director, was a fanatic that insisted on realism. Aquirre, played by Klaus Kinski, is obviously “nuts” from the get-go. At one point Kinski tried to flee the jungle and Herzog brandished a pistol and promised to kill Kinski if he escaped.

Just sit and watch this “happening”. It is slow, beautiful, and unforgettable. Hearing Spaniards speaking in German is admittedly a bit unusual, but there are English subtitles.

Violent, not for children. But a genuine screen classic.
