In 1970, the construction of a twin theater, Har Mar 1 & 2, was completed and became the Twin Cities' second double-screened cinema; its luxurious design included a "spacious lobby, with three Venetian glass chandeliers and bubbling fountains". It was owned by AMC and constructed by architect Benjamin Gingold Jr. In 1977, the larger of the theater’s two auditoriums was itself twinned, creating a triplex, as the theater was renamed the Har-Mar 3. In 1981, a former grocery store behind the theater was transformed into another eight small screens, giving the theater 11 screens total, making it the largest (and at times the top-grossing) cinema theater in the state.
