The document discusses location choices for filming a thriller video. It analyzes four potential locations - Southend Beach, Shenfield Train Station, a forest, and a rooftop in Brentwood. Southend Beach creates a sense of danger and isolation. Shenfield Train Station also builds tension through possible dangers. A forest was considered but only used briefly to reduce predictability. Finally, a rooftop was chosen for a scene of attempted suicide due to the atmosphere it provides and questions it raises for the audience. The locations aim to generate feelings of suspense, tension, and isolation to enhance the thriller genre.
