We were discussing the similarity of the technique used in creating these two "trick shots" which reveal simultaneous action from 
The Man Who Knew Too Much
 and 
Vertigo at the 
WWH Facebook page, and it got me thinking about other images and juxtaposed shots that Hitchcock repeated in his films—kind of like the second Mrs. De Winter's father who liked the paint the same tree over again.
Here are just a few that come to mind:
Of course Hitchcock used stairways so very often, but the framing he used in 
The Lodger
, 
Blackmail
, and 
Vertigo
 were strikingly similar. 
Designer Saul Bass had a hand in both the 
Vertigo
 title sequence and the shower sequence in 
Psycho
, but it was a design that Hitchcock chose in two of his key films.
The Catholic Hitchcock repeated variations of his own Pietà, but the images in 
The Lodger
 and 
Topaz
 are most similar.
As Hitchcock's films progressed in the 1950s he explored more deeply the  frailty of the human psyche. Notice how these two scenes in consecutive  films—
The Wrong Man
 and 
Vertigo
—are  nearly identical. Here a desperate Manny goes into Dr. Banay's office  to ask about Rose's condition. Dr. Banay leans back on his desk, arms  crossed, explaining the healing will take time. Later Manny departs,  walking away from the camera down the long corridor of the sanitarium.  Below, an equally desperate Midge goes into the office of Scottie's  doctor and departs down a similar corridor after telling the doctor  Mozart isn't going to help.
In each of these scenes from 
The Wrong Man
 and 
Psycho
  as the discussion turns to someone being institutionalized or being  "put someplace", both Rose Balestrero and Marion Crane begin clutching  and rubbing an arm.
In both of these scenes from 
The Man Who Knew Too Much
 and 
Topaz
, the listener is receiving information he'd probably rather not have heard.
It doesn't matter whether it's the police or a couple of henchmen, on  the front steps of your own home or through the lobby of a New York  hotel in broad daylight, Hitchcock knew that being taken into a car  against your will could be equally frightening and filmed these scenes  from 
The Wrong Man
 and 
North by Northwest 
in much same way.
Then, of course, there's the way Hitchcock filmed 
kissing scenes, but we covered that already!
