Thriller Micro Elements

Sound 
Use of non-diegetic soundtrack to emphasize the mood of the physiological / crime thriller, which is slow and dingy which links to the mind as if its like a time bomb e.g. repetitive tune. This is used to create a fearful atmosphere. The music is playing while he is dreaming to separate this from reality. The music then stops when he wakes up and talks with his wife.This also shows how the dreams are affecting him and he cannot stop thinking about them.

Editing
We use a flashback effect when switching from a dream back to reality, to make it obvious he is dreaming.
Use of credits as a type writer effect so it comes up slowly in time with the music. Also when the title comes we use a odd symbol effect to give the audience the idea that this story isn't very straight forward. A lot of thriller storyline will have twists in them so this follows the characteristic normally seen in a thriller film. 

Mise En Scene 
Use of rope as a prop to show the audience that Dom has been hung, and business cloths to represent hes at work, and a dressing gown showing it is late at night. This is very common of thriller movies because of the darkness and the unknown that comes with it and most crimes happen in the dark because they are less visable.
Dom white foundation to represent death whilst hanging, when you are dead you go pale, hanging represents the storyline of a murder that has been covered up, Psychological thriller because it plays with your mind.

Cinematography
Slow panning shots in time with the music to create a dark and doomy scene, panning across to pieces of crime evidence showing its a long and slow process. This is very common in thriller movies as the build up is normally slowly moving onto a quick bit of action.
Shot reverse shot when Browen and Adam have a conversation.
Birds eye view over the pieces of evidence to fill the screen making each piece clearer to see.

SFX
Use of fades and transitions when panning across to maintain and dark a slow atmosphere.
One scene was very dark when talking to Bronwen making it hard to see each person because of this we used a SFX to make the scene lighter.

 What we would do different?
Not use cheesy American accents.
Different locations as it made it less realistic being at college with lockers and board notices around.
Different story line, was completely run by Bronwen.
was occasional editing faults e.g. when it cuts to Bronwen it accidentally does another quick cut to her in another scene.
I would probably create a comedy thriller as it is difficult to create a crime / serious thriller scene at Long Road Sixth Form grounds.
