Soundtrack
Possible soundtracks could be-
https://www.youtube.com/watch?v=AUvx2q7a3_A
https://www.youtube.com/watch?v=GfO4XJZMGn4
https://www.youtube.com/watch?v=HitDB-Be_74

These are from film soundtracks like Drive, Tron Legacy, Interstellar which aren't all from my the same genre as my film but they are quite eerie and can build tension but are simple enough that they won't distract from the dialogue. Also some are the instrumental versions of songs, so you can have the tune without the lyrics distracting from the trailer.

I sent an email to the record company asking for permission to use some of the soundtracks in my trailer:

Locations
Scene 1 and 2 -

I've chosen to film around Digbeth and the Custard Factory to get an urban and industrial feel, especially with all the graffiti around that area. It's also quite empty around that area so there won't be that many people around. 

Scene 3 -

The scenes set at Max's house will be shot at my own house.

Scene 5-

For the scenes inside Max's I will create a wall with the clues and evidence they've found so far.

Scene 9-

For the warehouse at the end of the trailer, I plan to use a car park in Birmingham that is usually empty and looks like an abandoned warehouse.

Risk Assessment 
-When shooting in the city centre it is going to be dark, so we have to be careful when filming on the road incase of cars.
-When filming the kidnapping scenes we need to be careful that no one gets injured. 
-For the scene where there's a knife in the wall the actors have to be careful in case it falls out, or when she pulls it off the wall.
