Mise en scene is a French expression that is related to enactment or the positioning a scene. O mise en scene is also related to the direction or production of a movie or play.
This expression arose from the presentations of classic plays in France, in the 19th century, to define the movement of characters through the scenery and the positioning of objects on the stage.
It can also be considered mise en scene everything that appears in the frame, such as: actors, lighting, decoration, props, costumes, etc.
The term, however, was known to be used in the first "author films" in the beginning of the 20th century. Each "author-director" had his particular way of building a scene, being known for his mise en scene (mode to position the scene, ie light effects, camera framing, voice intonation, gestures and movements on the scene, etc).
Not being limited only to the technical part of production, the mise en scene has a striking feature in each "filmmaker-author" for the dramatic content it conveys, while using unconventional ways to build the scene.
Even the mise en scene being an expression used mostly in the film industry, the term can be used to define any kind of situation where you "build" a scene, setting the scene or others elements.
Example: At a birthday party, the birthday person, when choosing the decoration and the guests, is setting up the mise en scene of your party.
In French cinema, some of the great filmmakers who stood out for their mise-en-scene, were François Truffaut, Jean-Luc Godard and Alain Resnais, considered the pioneers of the movement of French Vague Nouvelle.
