Definition & Meaning of "four walls"

What is "four walls"?

In film production, four walls describes a shooting location that is fully enclosed, like a room with four complete walls. This type of setting can create a feeling of confinement or closeness in a scene, as the enclosed space naturally draws attention to the characters and their interactions. Filming in such an environment allows the director to intensify the mood, making the audience feel more connected to the emotions and dynamics of the characters. It also helps in creating a realistic atmosphere by providing a contained, authentic backdrop for the action.
