Mise-en-scene refers to everything visible within a shot or scene that helps tell the story, including props, costumes, lighting, location, and actor positioning and performance. It draws on principles of semiotics to use signs and their interpretation. There are six key areas of mise-en-scene analysis: color, costume, props, set/location, blocking/performance, and lighting. Color, costume, and lighting can be used to convey specific meanings and themes. Blocking refers to actor positioning in relation to each other and the camera. Props should be chosen to advance the story and actors directed in how to use them appropriately.
