Zombie Cliché Lookout:
A scene’s setting is one of many factors in establishing mood. Where a clean and well lit kitchen might imply safety and security, a disheveled office with broken furniture and pools of blood… not so much. Suffice it to say, getting the proper setting to compliment the tone of a particular scene is important, which is why location scouts play such an important roll in pre-production work. Any time a scene needs to be shot outside the studio, a location scout will find an appropriate area and make arrangements to shoot there. This involves factoring in such considerations as the cost of working in the area, availability of light and electricity, and how difficult it is to get the cast and crew to the site.
Or sometimes it involves just finding a boring old hallway and calling it a day.
