Like I said earlier, the movie is metaphorical for the world. Today we're seeing so many instances of monumental duplicity,.. I think that's the task, in a way, to show what an architect of duplicity this character is, in his simplicity, forthrightness and morality. It's a strange and wonderful study of how far a horrible lie can be taken in terms of a character.
[The only way actors could breathe on the sound stage was through an air regulator.] You couldn't get out,.. Because the camera crew was literally bolted in. You can't get out; you can't go up or down. It really brought home the visceral feeling of what those men were willing to put themselves through.
