Mise-en-scene refers to everything within a film frame that helps communicate messages visually, including settings, costumes, lighting, and character positioning. Key aspects of mise-en-scene are settings and props, costumes, facial expressions, lighting, character placement, and camera angles. Color, costumes, props, location, blocking, performance, and lighting are all elements of mise-en-scene that filmmakers manipulate to convey meaning and mood to the audience.
