Mise-en-scene refers to everything within the frame of a shot that can be controlled by the filmmaker, including color, costume, props, set/location, blocking and performance, and lighting. These elements are used purposefully to convey meaning and provide context. Color can represent moods or ideas, costumes reveal character traits and social cues, and props are handled intentionally to advance the scene. Location and lighting also shape the audience's understanding through atmosphere and emphasis. Mise-en-scene is a key tool for directors to tell stories visually through the crafted environment of the film.
