Leonard Maltin Review:

Vivid, fascinating portrait of a man obsessed (made by a man obsessed--see BURDEN OF DREAMS) who's determined to capture a shipping route on the Amazon, even though it means hauling a boat over a mountaintop, through hostile tribal territory. Then he's going to bring in grand opera! Astonishing and captivating movie, in spite of its length; admittedly not to everyone's taste.

Leonard Maltin Rating: ****
