"Here is the script of the first of the three Quatermass serials presented on B.B.C. television. The Quatermass Experiment was produced when space exploration still existed only in the imagination. And no other television serial has had such a tremendous impact. The story concerns the first manned rocket to be sent into space. When the rocket is brought back to earth by Professor Bernard Quatermass, there has been a mysterious change which threatens the future of life on our planet.

  The horror of the story is intensified by its realistic setting: a cinema in Pimlico, St James's Park, and finally Westminster Abbey. And Nigel Kneale's brilliant imaginationholds the reader spellbound, so that the impact of his story is as powerful in print as on the screen." - blurb from Penguin edition.
 

Kneale modified the scripts for publication. Technical terms and directions were simplified and a racist sub-plot from the later episodes was removed.

Eight photographs were included; these constitute the only photographic record of the later episodes.
