Psychological Doubling
Pairing the main character with a second character who mirrors them. The double shows what the hero wants, fears or secretly is.
How this film uses it
Bruno Anthony is Guy Haines' dark side in the flesh. He is the man who will do what Guy has fantasized about but never acted on. Hitchcock stages the film to show how much the 'respectable' person owes to the 'criminal' one.
Where to see it
The opening shots of 2 pairs of shoes walking to the train, cut so they mirror each other. You can see the doubling right there on screen before you see either face.
