The Cinema Effect: Illusion, Reality, and the Moving Image, Part II: Realisms, is on view at the Hirshhorn Museum through September 7, 2008. Just as for Part I: Dreams, no photography or recording is allowed. That makes reviewing and discussing the exhibit rather difficult.
Fortunately, human imagination is wonderful. Look at your screen and hear the first two paragraphs from the exhibit brochure. Your sense of the exhibit will be good sense if you are moved to move.
