As the British say "Lost City of Zed."

Rating: Null/10 (23 August 2017)

My wife and I watched this at home on DVD from our public library. Picture and sound are first-rate, the "extras" are brief and not terribly interesting.
The story here is based on a real British military officer turned explorer, Percy Fawcett. About a 20-year period is featured between 1905 and 1925. We see Fawcett, and later his son, on expeditions into South America, and his fighting in the first World War.
The lead is played very convincingly by Charlie Hunnam as Percy Fawcett. He had some experience in map-making and was asked to travel to S. America to establish the precise border between Bolivia and Brazil, to settle the dispute between those countries, and to do that required his party to travel to the source of a particular river.
There had been rumors for a long while of a "lost city" of a refined culture, and when Fawcett found remnants of pottery and other signs of civilization in the deep forest, thought to be unexplored, he became obsessed with finding that lost city. He would call it "Zed" representing the last find he hoped for.
It is an interesting glimpse into the early 20th century life in England, where men hardly hesitated to leave wife and children, often for years at a stretch, to go off exploring. The movie is more of a character study of Fawcett and those in his circle than it is of exploring S. America, although it contains a lot of that also.
As history tells Fawcett and his oldest son went off in 1925 for what turned out to be his final expedition. The movie dramatized what "might" have happened but no one really knows. Did they find the city and decide to live there? Or were they murdered by the indigenous tribes? My bet is on the latter.
