"In the theater, while you recognized that you were looking at a house, it was a house in quotation marks … on screen, the quotation marks tend to be blotted out by the camera. The problem was to sustain at any cost the feeling you had in the theater that you were watching a real person, yes, but an intense condensation of his experience, not simply a realistic series of episodes. It isn't easy to do in the theater, but it's twice as hard in film."
