Mark Gatiss's adaptation of HG Wells's science fiction classic. July 1969, and as the world waits with bated breath for the Apollo astronauts to land on the Moon, a young boy meets 90-year-old Julius Bedford. He's a man with an extraordinary story of how, way back in 1909, he got to the Moon first, and, together with the eccentric Professor Cavor, discovered a terrifying secret deep beneath its seemingly-barren surface.
