Herzog's epic-feeling but actually pretty spare take on one man's mad quest to travel downriver and find the fabled city of gold El Dorado in 16th century South America. And if you're looking for the one man with the maddest mad quest credentials, there is only Klaus Kinski, at his insane best here both on- and off-screen.  Come for the history, stay for Kinski as King of the Monkeys.  The wildest fo wild rides.
