In a play ... a psychological loop is established between performers and audience. Nothing like this can occur in a movie theater. The images on the screen are patterns of light, not living actors. They are not affected by applause or hissing. They will be the same in a packed house or an empty one. And they will be the same every time the movie is shown. This affects the audience. Occasionally, movie audiences applaud or hiss or walk out, but for the most part they are passive. No social bond between the audience and the actors can exist.
