fourwalling
v.— «How, in these inflationary times, do you persuade the public to pay $23 million to watch your old home movies, mixed in wish some stock wildlife footage? Answer: You call the confection the “Great American Something,” or simply the “American Something”—and you four-wall it.…This new marketing technique, so-called because the film-maker literally rents the theater’s foour walls himself, has already made fortunes.…Dub’s astonishing success is due almost entirely to his adroit use of four-walling.» —“‘Four-Walling’ Hikes Movie Profits” by Charles Foley News Journal (Mansfield, Ohio) Oct. 27, 1974.
