Millions of viewers have enjoyed Saludos Amigos and The Three Caballeros without realizing that these Disney films were produced for a specific diplomatic purpose: as part of an initiative to foster a spirit of friendly hemispheric unity by countering Nazi propaganda efforts in South America, so that all the Americas might stand together against the Axis powers. This effort, the Good Neighbor program, was initiated and guided by Nelson Rockefeller as head of the Coordinator of Inter-American Affairs (CIAA), a new government post created by President Roosevelt in 1940. Beginning with the extraordinary research trip Disney undertook in 1941, leading a team comprising his top animators, artists, and writers from Mexico to Chile, renowned animation historian J. B. Kaufman reveals the story behind Disney’s contribution to Rockefeller’s program. Based on extraordinarily comprehensive archival research and richly illustrated with many images never before published, South of the Border with Disney is a fascinating study of an all-but-forgotten aspect of the American war effort that will inform and delight Disney fans, animation lovers, and World War II buffs everywhere.
