In September 1966, a Hollywood actor named Eric Fleming climbed into a dugout canoe on the Huallaga River in northern Peru for location filming on an ABC television production called High Jungle. Fleming had just finished eight seasons as trail boss Gil Favor on Rawhide - the long-running television Western that launched Clint Eastwood's career. The canoe capsized in the river's current. Fleming was swept away and drowned. His body was pulled from the water three days later, miles downstream. The Huallaga did what the Huallaga had been doing for centuries: it took what it wanted and did not return it on a schedule.
