A groups concept was notably similar to ours where they would take a monologue from a book, The Outsiders (?) I think was the name. From what I can recall it was a monologue from a character in isolation and was an unreliable narrator. Having read the book many years ago I think this was the case. Anyway, I was wondering about how to portray a monologue within the context of our studio. The obvious thing to think of would be night and day scenes. These scenes would have different tones and depending on the delivery of the monologue it could be a vastly different tone to fit night or day.
For instance, achieving different tones by using hard or soft light and even combining such techniques with cutting or distorting light to convey the isolation and delusion of the character giving the monologue. I remember them talking about a jail cell or a room of isolation, in my head, the way I would achieve that is cutting hard light onto the scene to achieve an isolated feel, that there is barely any light coming through to the room in order to pursue that feeling of isolation within the scene. The lighting I feel would most likely be minimal, only to light the subject to achieve that feeling of loneliness. However if the subject were to be portrayed as unreliable and emotionally unstable, cutting between a dimly lit room and a room filled with daylight can play into that scene if it is the intention of that certain scene.
Also the use of the camera is also very important to this scene. Things to consider when shooting a scene like this would be camera movement and camera cuts. It would be helpful to think about how many cuts and how much movement are you willing to use in order to portray the loneliness and isolation the character is feeling, especially if the character portrayed is a young boy (as it is in the novel). Using a shallow depth of field also helps with the use of close-ups and having the light focused on the subject would help add to the native tension and tone of the scene.
