In 1941, celebrated animator Walt Disney went on a diplomatic mission to Latin America. The creator of Mickey Mouse and Donald Duck became a good will ambassador. The U.S. had not yet joined its allies in war, but feared growing Nazi and Fascist influence in the Americas.   President Franklin Roosevelt had created a Good Neighbor Policy to improve relations in the hemisphere and Disney was asked to serve his country. In August of that year Disney and his team of artists, writers and composers set out on a 10-week journey to the region. Filmmaker Ted Thomas recreates the trip in the documentary, "Walt and El Grupo [the Group]."
