The document analyzes the mise-en-scene, lighting, costumes, locations, props, and sounds used in the film sequence "The Descent." It describes how the lighting creates a warm feeling for the birthday cake scene, but takes on a greenish glow in the hospital scenes. It notes that Sarah remains in her hospital gown throughout and the locations transition from pitch black to a hospital bed to the corridor. Sounds like the life support machine beeping and lights shutting off are also discussed.
