Four-wall distribution

In the film industry, four-wall distribution (also known as four-walling) is a process through which a studio or distributor rents movie theaters for a period of time and receives all of the box office revenue. The four walls of a movie theater give the term its name. Companies engaging in this practice were common in the United States during the late 1960s and 1970s; one of them was the Utah-based Sunn Classic Pictures.
