Four walls (filmmaking)

Not to be confused with Four-wall distribution or Fourth wall.

The four walls (also known as the four wall system) is a film production system whereby a film production company rents a sound stage and associated space but then separately contracts for additional facilities and hires freelance staff. The four walls system became prominent in the 1960s,^[1] following the demise of the Hollywood studio system from 1948.^[2] Some big studios, like Pinewood Studios in England, became four walls facilities^[3] for independent film producers and television companies. These facilities no longer engage in the development or distribution of films.
