Location report.

Corridors from an old work place of my Mum's in which is used as offices but can be used to show a dark prison corridor:

Outside a prison in Brixton (London):

This is suitable for my film, as it is a dramatic looking prison and looks like it belongs in a council estate.

High rise flats in Brixton (London): These are suitable for my sequel as they look almost identical to the ones in the previous films and it has the ability to carry the story on through.
