At the start of the sequence there is a loud bang which is used to give an instant hint to the audience that the film will be tense and alarming.

 

Then a hand is writing into a notebook, however the lettering is blurred so we cannot to see what is being written, but just by the sounds of the pen being pushed down the character is represented clearly and it is obvious for whatever reason they are heated and determined with what they are trying to succeed. Then some random noises can be heard which creates an uneasy atmosphere to the audience and although they feel out of place and on edge they still want to watch on to figure out what is going on, meaning the director has effectively created narrative enigma through the assortment of the music and sound effects which is a common convention of thriller films. Then the speed and the volume of the music increases, the drum bang is now more noticeable.

 

From the beginning to the closing stages there are continuous short takes and the fact not one thing is in focus for a long time creates an uncomfortable and nervous feeling of what is going to happen, but it is entertaining which will keep the audience involved. The majority of each of these shots are close ups, this draws the viewer closer and involves them further in what is happening. This would encourage them to observe in greater detail the build of up tension. When the camera cuts away regularly in order for the credits to show, it switches from being still to a handheld shot. This could create uncertainty for the audience, and leave them wondering who is behind the camera. 

​

From the very beginning the director decides to use a jump cut, and the metal object which is being held is shown in multiple angles with altered lighting, to deliberately confuse the viewer. During the course of the sequence non continuity editing is persistently used, this stops the clip from feeling like ‘real life’ for the viewer, which would make them even more anxious as they realise that anything could happen throughout this film. With the slow motion of the page turning they can actually focus on what is happening, helping them to engage more into the story line. Finally, the visual effect of the credits draws the audience’s attention to them, emphasising again the suspension of the film following. Below are screenshots of the various editing techniques the director has used for the opening sequence.

The props used in the sequence could be associated with investigations and detective work. These include books, photos, files, pens and paper. It appears as if the person is putting pictures and information into one file or case and all of the objects are shown very close up and therefore they take up most of the frame. This creates suspense as the audience do not know who is creating this file and doing these things as they cannot see their face or where they are.
