details from the IMDB page for "The Lost City Of Z"

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.

Benedict Cumberbatch is listed as playing Lt. Col. Percival Fawcett

from Deadline

Benedict Cumberbatch is negotiating to star in Lost City Of Z, which James Gray will direct from a script he adapted. Panorama Media will finance the film and handle foreign sales. 

The film is based on the David Grann bestselling book. Cumberbatch is in talks to play Percy Fawcett, who in 1925 headed into the depths of the Amazon jungles in Brazil. Fawcett was there to map the jungle and, hobbled by malaria, he discovered a mythical city he called The Lost City Of Z. Scorned by peers who claimed that this ancient kingdom was a fraud, Fawcett headed back into the jungle with his son and one other, braving the dangers of disease, insects, snakes, poison darts and other hazards to reinforce his discovery. None of them were ever seen again and it remains one of the great exploration mysteries of the 20th Century. 

Plan B‘s Brad Pitt, Dede Gardner, Jeremy Kleiner and Anthony Katagas (who worked with Cumberbatch on 12 Years A Slave) will produce. Plan B has been developing the project for several years, and it initially seemed like Pitt would be heading into the jungles.
