Today, Ironically, technological development has resulted in a surveillance state which is far more extreme than Orwell's dystopia. "Even the Catholic Church of the Middle Ages was tolerant by modern standards. Part of the reason for this was that in the past no government had the power to keep its citizens under constant surveillance." George Orwell — 1984
This movie does not understands 1984. The character in the screen talking to the audience is the resistence's lider, in the novel by Orwel. He is not Big Brother. The session was called the "hour of hate". During the "hour of hate" individuals would ear the resistance's lider speach and then explode in insults against him. The Lennie Riefenstahl character kills the hope for resistance.
