The story is about how a young man dreamed of building an Opera house in the jungles of Peru. He encountered many difficulties and even had to drag a streamboat across a mountain in the process!
Had a pleasant surprise initially when I saw that Claudia Cardinale was the lead actress but realised that it had been almost twenty years since she acted in Fellini's "8 1/2" and Visconti's "The Leopard". She still looked beautiful but not as young as before. Liked the nice jungle adventure and the great acting by Klaus Kinski!
