You might think you already know everything you need to know about the Apollo space program that galvanized America in the 1960s. But David Sington's remarkable documentary proves you wrong. Using never-seen NASA archive footage of the nine moon missions attempted from 1968 to 1972 and fresh interviews with all the surviving astronauts, save the elusive Neil Armstrong, the film is a bracing reminder of a moment in history in which pride is justified. OK, the rah-rah gets a bit thick at times, especially a soundtrack that won't stop at rousing. But the insipid soon becomes inspiring as the astronauts recall raw details, and we watch in amazement at the wonder and tragedy on view. Want to know what the "right stuff" really is? Take a look.
