Much of the film was shot on location; the "cricket match" and "hayride" scenes were shot on the real dish and researchers often postponed experiments to position the dish for photography. The set reconstructing the 1969 control room was extremely accurate, down to some details as small as ashtrays. Some of the "props" were in fact original NASA equipment used during the Apollo 11 landing, left behind in Australia as they were too heavy (i.e. too expensive) to ship back to the U.S. Staff from that era expressed amazement at seeing the set; they said it was like stepping through a time warp.
