Gracias Amigos was a 1944 propaganda short produced by the Office of the Coordinator of Inter-American Affairs to educate the American public about the contributions of Latin America during World War II. The narrator tells the audience that there were stores of those raw materials in the Western Hemisphere, but someone had to get them, and want to get them. So the Rio conference of 1942 is organized, and the various republics commit to solidarity to the US and the Allied cause. The film shows the many vital uses these resources are put to, including rubber and quinine.
