Having already swum the full lengths of the Danube, Mississippi and Yangzte, the extraordinary manic obsessive Slovene Martin Strel, makes a 70 day attempt to repeat the effort in the Amazon. If what you expect is a super-athlete that's not what you get, this overweight 50-year-old eats horseburgers, drink drives and wires batteries to his head! What he is though is a hero, a man dedicated to and succeeding in extraordinary non-rational tasks. Fascinating stuff - more Herzogian than Aguirre or Fitzcarraldo could ever be.
