The mission of the OCIAA was cultural diplomacy, promoting hemispheric solidarity and countering the growing influence of the Axis powers in Latin America. The OCIAA's Motion Picture Division played an important role in documenting history and shaping opinion toward the Allied nations, particularly after the U.S. entered World War II in December 1941. To support the war effort—and for their own audience development throughout Latin America—Hollywood studios partnered with the U.S. government on a nonprofit basis, making films and incorporating Latin American stars and content into their commercial releases.
