Hitchcock's The Man Who Knew Too Much

The Police station scene:

I like that scene because there is a mystery man who is telling the main character that he should not talk anything about what he knows to the police.

How does it feel? Uncertainty. Fear of his boy.

How that has been achieved? A call phone of unknown man. Stewart's expression. The CU moving shot from the phone to his face and slow motion of the forefinger.

Has the mise-en-scene played a part in this? The space where is sitting the unknown looks threateningly. The long shadow of the chair. The table with grapes, the checkered floor .

Is there any meaning conveyed by the mise-en-scene? There is someone very powerful who wants that the doctor must not tell what he knows to police. 

The calling scene: I like here how two shots are connected to build tension.

The hotel room scene:  I like here the Steward's shadow when he looks on his sleeping wife.

How does it feel? The light here is perfect. It is night and they must leave the Marrakesh to find their son in London. There is again an uncertainty and Stewart packing their things.

How that has been achieved? I think the light here is strong element, the Stewart's expression and the fact that his wife is sleeping because he administered to her a sedative to overcome the fact the their little boy was kidnapped.

Has the mise-en-scene played a part in this? The room is here shoot  from different angle than we have seen it before. The color and decoration helps to give a sense of different world. The contrast is Stewart's suit and the decoration. That they are leaving supports the open baggage, he is packing. That there is problem or tension supports the fact that his wife is sleeping and he is looking on her.

Is there any meaning conveyed by the mise-en-scene? Maybe that he is the main character who can change / or have the situation under control.

The police station but in London: I like the file closet which represents the main thing that reminds that we are in a police office. I like the high angle when the couple is receiving a call.

The echoes:  Amazing scene where I firstly thought that there is problem with sound. Hearing the steps in echoes build the tension that there is something strange. I like the shot where the camera is moving forward and looking back and a stranger appears at the corner and is walking to us. Great tension, angles of camera. The scene is empty we are only focused on the sound and those two characters.

The church scene.

How does it feel? He is closed and locked in the church, he is alone, his wife somewhere outside gives call to police. She is only hope for him and their boy.

How that has been achieved? Empty church, somebody is closing and locking the entry.

Has the mise-en-scene played a part in this? Those empty chairs in wide shots are strange and tell us that nearly nobody is there.

Is there any meaning conveyed by the mise-en-scene?  I think we think that the church is a place of piece but when the main entry is closed we are not sure what is hide. And in this case it is very dangerous to know it.
