Mise-en-scène (mi.z‿ɑ̃.sɛn; "placing on stage" or "what is put into the scene") is the stage design and arrangement of actors in scenes for a theatre or film production, both in the visual arts through storyboarding, visual theme, and cinematography and in narrative storytelling through direction. The term is also commonly used to refer to single scenes that are representative of a film.
Mise-en-scène has been called film criticism's "grand undefined term." It has been criticized for its focus on the dramatic design aspects rather than the plot itself, as those who utilize mise-en-scène tend to look at what is "put before the camera" rather than the story. The use of mise-en-scène is significant as it allows the director to convey messages to the viewer through what is placed in the scene, not just the content of the scene. Mise-en-scène allows the director to not only convey their message but also to implement their aesthetic. With that, each director has their own sort of mise-en-scène that is unique to that one person. Mise-en-scène refers to everything in front of the camera, including the set design, lighting, and actors, and the ultimate way that this influences how scene comes together for the audience.
When applied to the cinema, mise-en-scène refers to everything that appears before the camera and its arrangement—composition, sets, props, actors, costumes, and lighting. The various elements of design help to express a film's vision by generating a sense of time and space, as well as setting a mood, and sometimes suggesting a character's state of mind, whether that be happy with bright colors or sad with gloom and darker colors.
Mise-en-scène also includes the composition, which consists of the positioning and movement of actors, as well as objects, in the shot. These are all the areas overseen by the director. One of the most important people that collaborate with the director is the production designer. The directors, the cast, and the workers who control decorations and sound all have input on the Mise-en-scène and come together to make sure it fits in perfectly with the film.
