Both a documentary and a unique exercise in film restoration, It's All True tells the complex story of Orson Welles' ill-fated attempts to make an anthology film about the life and culture of South America and concludes with a reconstruction of one of Welles' unfinished segments, edited together from rediscovered original footage. The idea for Welles' South American project was conceived by the American government as a sort of cultural exchange to improve relations with Latin America. Using interviews and period footage, the filmmakers relate how the project quickly turned sour, as both the Brazilian government and RKO studio executives objected to Welles early footage; indeed, thanks to a local witch doctor, the film could literally be said to be cursed. Although Welles persevered, RKO eventually withdrew support from the project. The failures of It's All True and The Magnificent Ambersons, which was damaged by studio cuts made while Welles was overseas, are thought by many to have irreparably damaged the director's Hollywood career. It's All True concludes with a partial reconstruction of the "Four Men on a Raft" segment, in which Welles tells the true story of a dramatic, thousand-mile raft journey by four Brazilian peasants.
