(1942) This program sought to foster understanding between North America and Central and South America, another part of Welles’s war efforts. Sponsored by the U. S. Office of the Coordinator of Inter-American Affairs. Fifteen-minute episodes.

Welles embarked on producing Hello Americans soon after returning from an extended tour in South America. In 1942 he spent several months with a crew filming in Brazil for a never-realized film project called It's All True, while attempting to supervise post-production on The Magnificient Ambersons from afar via phone and telegram. His soujourn was sponsored by both the studio RKO and the U. S. Office of the Coordinator of Inter-American Affairs. The filming ran way over budget and ruined Welles's relationship with RKO. Inter-American Affairs continued to use him as a good-will ambassador and engaged him to work on this rado series, produced simultaneously with Ceiling Unlimited.
