For our OTS we decided to film in an non linear fashion, similarly to se7en and dead silence. Therefore, we didn't need an outside location due to us filming primarily in one location. We filmed on a table within the edit suite, we did these as it when the camera was set up and the lights were switched off, what the audience would see would be a cramped, enclosed area. This creates a tension as the audience feel as they are in this enclosed space. Additionally, by using one location within the school it meant we could leave props in the same room instead of having the risk of damaging or losing them on set if we were filming at an external location.
