A movie is like a tip of an iceberg, in a way, because so little of what you do in connection with making a movie actually gets into the movie. Almost everything gets left behind.
Errol MorrisIf someone tells you that George Bush is not the 43rd president of the United States, they might be engaged in wishful thinking, or denial, but if they make that claim, it's either true or false! And you can assess that, regardless of whether there's an omniscient narrator, or an unreliable narrator, or it's shot in vรฉritรฉ, or it's manipulated, it's agitprop, whatever! It makes no difference! It's a style!
