In 1942 RKO Pictures underwent major changes under new management. Nelson Rockefeller, the primary backer of the Brazil project, left its board of directors, and Welles's principal sponsor at RKO, studio president George Schaefer, resigned. RKO took control of "Ambersons" and edited the film into what the studio considered a commercial format. Welles's attempts to protect his version ultimately failed. In South America, Welles requested resources to finish "It's All True". Given a limited amount of black-and-white film stock and a silent camera, he was able to finish shooting the episode about the jangadeiros, but RKO refused to support further production on the film.
