The first scene is an establishing shot-wide shot. Cinematography- the camera is positioned low down and tilted up, it could suggest that someone is watching the character and/or feels that we as the audience have intruded into his room, as the camera is positioned in a place where you can actually see the door open as you can see here
Mise en scene- It is quite dark, there is only a lamp to give a little bit of light (low-key lighting), so already this could connote mystery. Also it could show the vulnerability of the character in bed, darkness could foreshadow something which is going to happen.
There is a bed, lamp, picture, window, curtains, furniture=bedroom. The old furniture and books represents his age- intelligence, old, clever and sophisticated
Sound- the sound is off-screen= diegesis are sounds like talking and cars outside which suggests he lives in the city.
A close-up shot is used to show that the object which he is putting on the table, which is his glasses, this could also add to the character's vulnerability as it shows that he has to wear glasses which also suggests that he is quite old, as all the elements add up in the mise en scene that the character is quite old.
Close-up shot on metronome, the sound of the ticking noise is diagetic, the beat/rhythm of the ticking noise is steady but quite distinctive as it creates suspense because it is like the beat of the heart.
After the opening scene which shows the character in his bedroom, it suddenly goes to a black frame, which creates suspense and surprise as the audience does not know what is going to happen. It also creates tension, and it is quite scary also because when it goes to the black frame it uses a sound effect which sounds like thunder/explosion which is quite surprising and creates more tension.

This is an extreme close-up shot of what appears to be a book, it also shows someone's hand turning the pages over, so this also creates suspense and mystery as to who the person is? What kind of book is it? So it makes the audience question, so the use of this shot is very effective. The production company is also placed in this scene, because normally at the beginning of films the production company, title, cast etc. are shown. It is placed in a creative way as you can still see what is going on in the scene but at the same time you can also read/see it clearly. The text is in capitals, the colour of the text is white and the font is not fancy/elegant writing, it is quite bold.

The next scene goes to another black frame, again with white, bold text, which is quite a horror type of text and whilst this is showing, music is playing which is non-diabetic, the music has a genre of horror/thriller. The second picture shows that the first scene faded into the next, so the text stayed the same but the background changed. The background in the second picture shows two hands which are drawn with a red line drawn in the middle, it is also quite dull, so this also creates suspense as to what is going to happen and why there is a sketch of two hands.
In the next scenes, there are a series of extreme close-up shots used:
The use of extreme close-up shots are very effective as it creates suspense and tension for the audience, as you can see the objects which are shown, but as the audience we do not know what the objects are/are used for, so we begin to think and ask questions as to what will happen next. You can also see in all of the extreme close-up shots shown above, there is always someone's hand shown handling the objects, which also creates suspense and mystery because it does not show the whole character.

The four screen shots shown above are also extreme close-up shots but they also contain text which shows "casting by" and "music by". The two screen shots on the left has a black background so that the white text and the image shows clearly, black connotes darkness, mystery, thriller and horror which relates to the genre of the film. Also, the first screen shot on the left shows an image of a person's face with a line crossed through their eyes, and then there is an edit to show that the whole face has been scribbled in, which suggests something about the character, that the character has anger or a plan to do something with that particular person.
This is an establishing shot which sets the scene of a city and also shows the day which it is so it gives a bit of important information to the audience which may make sense during the rest of the film to the audience.
