Location recce

The film will have a lot of low level lighting and have a pale colouring, to build a sense of fear. 
Sound:
When Tim is in the bedroom there will be diegetic sounds like a door creaking and heavy breathing. In the park the swings will creak giving a sense of danger but also the idea of being old and neglected. In the cafe there will be lots of murmuring but it will fade out into silence to make the audience feel like they are in Tim's shoes, overcome with emotion causing him not focus.  When Tim walks down the street, you will be able to hear the wind as well as creepy non-diegetic  music. This will build up the tension and perhaps the fear with have of Tim and what he is capable of doing.
