For this film, the Roosevelt Memorial Association compiled footage from Theodore Roosevelt’s 1913-1914 trip to South America during which he combined a series of lectures with an expedition in the Amazon Valley of Brazil to collect zoological specimens. The Roosevelt group was combined with a group of Brazilian scientists under the leadership of Colonel Rondon to explore the course of the uncharted Rio da Dúvida, the River of Doubt. In 1926, G. M. Dyott, an English explorer, was asked by the Roosevelt Memorial Association to retrace Roosevelt’s voyage down the River of Doubt and to film his trip in order to supplement the footage from the 1914 trip.
