Cell culture molecular biology primarily involves cultures of cells on flat plastic dishes. This technique is known as two-dimensional (2D) cell culture, and was first developed by Wilhelm Roux who, in 1885, removed a portion of the medullary plate of an embryonic chicken and maintained it in warm saline for several days on a flat glass plate. From the advance of polymer technology arose today's standard plastic dish for 2D cell culture, commonly known as the Petri dish. Julius Richard Petri, a German bacteriologist, is generally credited with this invention while working as an assistant to Robert Koch. Various researchers today also

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
