Rio das Mortes is a 1971 color film written and directed by Rainer Werner Fassbinder. One of the early Fassbinder films it stars Hanna Schygulla as Hanna, Michael Knigde as MichaelMike and Gnther Kaufmann as Gunther.
This is Fassbinders 8th film, one that as a TV film did not receive much attention. It is listed as a comedy and gives a biting commentary about the lives of common people in urban West Germany at that time. Fassbinder gives credit to Volker Schlndorff for the idea of the plot. The film has been criticized for sloppiness and poor character development while the acting is commended. The ignorance of the two adventurers is underlined by the fact that the actual Rio das Mortes is located in Brazil, not Peru and that they try to find Mayan treasure there. In a memorable scene Schygylla dances with Fassbinder who plays an unidentified stranger.
