Mise-en-scène refers to everything that appears before the camera and its arrangement, including composition, sets, props, actors, costumes, and lighting. It also includes the positioning and movement of actors on set, known as blocking. Mise-en-scène is used by directors to give an impression of characters or situations without dialogue. Key aspects of mise-en-scène include décor, lighting, space, costume, and acting style, all of which help tell the visual story.
