The Lost City of Z Movie

In 1925, Fawcett ventured into the Amazon to find an ancient civilization, hoping to make one of the most important discoveries in history. For centuries Europeans believed the world's largest jungle concealed the glittering kingdom of El Dorado. Thousands had died looking for it, leaving many scientists convinced that the Amazon was truly inimical to humans. But Fawcett, whose daring expeditions inspired Conan Doyle's The Lost World, had spent years building his scientific case. Captivating the imagination of millions round the globe, Fawcett embarked with his son, determined to prove that this ancient civilization--which he dubbed Z--existed. Then his expedition vanished. The Lost City of Z is both written and directed by British filmmaker James Gray, of Little Odessa, We Own the Night, Two Lovers and The Immigrant previously. Adapted from David Grann's book. It first premiered at the 2016 New York Film Festival. Amazon Studios opens The Lost City of Z in select theaters starting April 14th, 2017 this spring.
