Quatermass and the pit - Kim Newman

While digging an extension to the London Underground Railway, workmen discover an object which might be an ancient Martian spaceship - and Professor Quatermass of the British Rocket Group investigates a mystery which prompts frightening revelations about the origins of humanity itself.
Before 2001: A Space Odyssey and Doctor Who, Quatermass and the Pit was the paramount British science fiction saga in film and television. Kim Newman's fascinating study focuses on Roy Ward Baker's 1967 film, written by Quatermass creator Nigel Kneale for Hammer Films, but also looks at the origins of the Quatermass franchise in 1950s BBC serials and earlier films.
Exploring the production and reception of the film and series, Newman assesses the lasting importance of this landmark franchise.
