>The WOPR computer, as seen in the film, was a prop created in Culver City, California, by members of the International Alliance of Theatrical Stage Employees Local 44.[13] It was designed by production designer (credited as a visual consultant) Geoffrey Kirkland on the basis of some pictures he had of early tabulating machines, and metal furniture, consoles, and cabinets used particularly in the U.S. military in the 1940s and 1950s. Art director Angelo P. Graham adapted them in drawings and concepts. The WOPR was operated by a crewmember sitting inside the computer, entering commands into an Apple II at the director's instruction.[13] The prop was broken up for scrap after production was completed.
