The filmmakers chose to film the opening of their crime drama in the front room of a typical suburban house in South London. This location allows them to easily film inside without worrying about weather and bring in equipment like lights and tripods. The normal house setting also fits the crime drama convention and is relatable to audiences compared to rural areas which are seen as safer than cities. The room has large windows and light walls to film in natural light and make the opening seem higher quality despite only using one setting.
