My opinion is that lighting is the one of the most significant factors when filming because you have to make sure that you highlight objects/people which will provoke an emoting response from the audience. Because our film is an action/thriller the mise-en-scene should laid out in a certain way and shouldn't always be bright, it should kind of dark to get the scared response you want from the audience. The low-key lighting coupled with the diegetic sound builds the suspense and makes the audience feel anxious and edgy.
