Chicago Reader review:
The most densely allegorical of Alfred Hitchcock's masterpieces (1954), moving from psychology to morality to formal concerns and finally to the theological. It is also Hitchcock's most innovative film in terms of narrative technique, discarding a linear story line in favor of thematically related incidents, linked only by the powerful sense of real time created by the lighting effects and the revolutionary ambient sound track. James Stewart is the news photographer who, immobilized by a broken leg, dreams stories about the neighbors in his courtyard and demands that they come true. With Grace Kelly, Wendell Corey, Thelma Ritter, and Raymond Burr.
Here (and above) is the trailer.
