Filming locations and final one

We deicded to film in ST Stevens street as the area is glum and run down, it is a typical city street normally full of people and noisy as well as being a hotspot for trouble. we decided on useing the underpass near there as a focal point, as its disorientation and very run down, its normally full of homeless people and is notorious for crime and illegal happenings.
The streets around St Stevens street feature many old and gloomy looking buildings which along with Norwichs almost completely greyscale theme would suit the thriller genre.
