Discount theaters, also known as ollar theatres, dollar movies, second-run theatres, and sub-run theatres, are movie theaters that show motion pictures for low prices — often for as little as a dollar — after the films leave first-run theatres. These low-cost movie houses had their heyday in the 1980s as Hollywood studios were churning out motion pictures quickly, and the number of American screens had not yet expanded to catch up with the supply. These theatres, often the older theaters in older parts of town, typically had just one or two screens while newer multiplexes were built in the suburbs for first-run films.
