"In the theater the audience is generally riveted to a single angle of observation. The movie director, though, can rapidly shift from objective to subjective--and to any number of subjective points of view--and in so doing seem to pull the audience directly inside the frame of his picture, giving the spectator the sense of experiencing an action from the viewpoint of a participant. Identification of the viewer with the film character, then, can be much more intimate than the analogous situation in the theater."
