The film is undoubtedly orchestrated, although the filmmakers (as part of a marketing ploy) continue to vehemently deny that fact. When confronted with the question of its honesty at a Q&A session, one of the producers sardonically claimed that it was fake and that his brother is a better actor than Marlon Brando. In fact Nev's performance is very good, but he's merely playing a naive and wider-eyed version of himself, not a character.
In short — its fake. And it will be revealed as such in the near future, most likely around the time of the its release. The filmmakers will defend themselves by framing it as a social project or an exploration of the human psyche in an internet age... maybe it is. But calling a fake documentary real is nothing more than manipulation for profit."
