Mise-en-scene of Rear Window's (Alfred Hitchcock) opening scene

a) An urban ambience is conveyed, creating this sense of close together/packed up society, as we can see the several tall buildings and the cars, evoking a busy situation, a contunuity of a routine, creating a stereotypical, NORMAL, situation. Also, a nearly claustrophobic feeling is created by this enclosed environment. The light-rythm and stable cadences of the music also help convey this "normal" situation, an everyday routine. The stillness of the shot helps the audience perceive the movements inside it: the blinds going down showing more detail each time, the cars passing by, people moving. 

b) The camera suddenly zooms in the set from inside the place in where it was, so it creates the effect of being a point of view, of being the eye of the character the audience will soon see. This represents the character as being a watcher, a spy of this environment. It foreshadows the role of the character, who, from the space in where the camera in placed, looks all around him all day long (this is then conveyed as the camera starts showing the whole set, rotating and "looking" at it).
