Which actor tragically drowned whilst filming two episodes of the TV series "Off to See the Wizard"?

Eric Fleming (born Edward Heddy Jr.; July 4, 1925 – September 28, 1966) was an American actor and writer, known primarily for his role as Gil Favor in the CBS television series "Rawhide".

Fleming signed to topline "High Jungle", an adventurous two-part episode of the short-lived MGM-ABC "Off to See the Wizard" anthology also intended for theatrical distribution in Europe. Six weeks into the location shoot in Peru, Fleming and co-star Nico Minardos were in a dugout canoe that overturned in the Huallaga River. Minardos managed to swim to safety. Unfortunately Fleming was swept away by the current and drowned on September 28, 1966, at age 41. He left behind his fiancé Lynne Garber. "High Jungle" remains lost, but photographs have managed to survive.
