Rough, no question, but I wonder if some Hollywood resources couldn't tidy it up a bit. It would make a great DVD extra.
In it's playful use of audio snippets and "found footage", Linguagem de Orson Welles reminds me quite a bit of F For Fake. I especially like the part where footage of Rockefeller and Disney arriving in Rio is shown while, on the soundtrack, Welles as the Shadow is heard saying, "Who knows what evil lurks in the hearts of men?". I also find myself curious as to why the film ends with a shot of New York's Chrysler Building.
