Four-part series using rare, private and commercial colour film and photographs to give poignant and surprising insights into the 1930s. One of the most prolific collectors of colour film in the period was the American industrialist Harry Wright. A self-made millionaire with a passion for film, he acquired and commissioned hundreds of films, which he screened for guests at the private cinema he had built in his home in Mexico City. The programme examines Wright's extraordinary colour films of Africa and Central America, including his so-called Ethnographic Series of Unknown Mexican Indians, a unique visual record of the lives and customs of indigenous peoples living in the remote rural regions of Mexico.
