Shadow of a Doubt (1943) - Alfred Hitchcock

Whilst watching the opening sequences of 'Shadow of a Doubt' in class, we analysed every aspect of it.
The sequence opens with old-fashioned dancing representing the past. The scene then dissolves to a polluted, industrial setting. There is a long-shot to show the setting, then zooms to the window suggesting that this is where the main character is.
When the setting changes to the room through the window, the main character (Charlie) is lying on the bed (could be either the protagonist or the antagonist at this stage). There is lots of money scattered around carelessly, with luxury items on show. Apart from the hand moving, character seems lifeless. He barely registers when the woman enters the room; he shows no reactions and emotions are highly controlled. Next, when the woman pulls down the blinds; a shadow is drawn over his face and he seemingly comes 'alive' again - representing his dark personality.
The next scene shows him going to meet two other men who have been either looking for this man, or following him. The music is very tense, creating a very unsettling atmosphere.

The later scene is set in a rich, peaceful and energetic town. Hitchcock uses the same technique of zooming into the window, then into that perceived room where the niece of Charlie is. She is laying in the exact same position as him suggesting she is the 'mirror image' of him.
This film includes the film of mirroring.
