This is the final part of Hammer’s Quatermass trilogy adapted from the BBC serials. There is obviously a modest budget- the sets are bare and the effects and models are scarcely state of the art even for the '60s. Though they are still an upgrade from the tv originals. And this one is in colour.
The main attraction is Nigel Kneale's erudite, beguiling concept which reaches back into deep history in search of the horrific origins of man's bloody nature, replete with fascinating ideas of how this origin story manifests itself throughout history in apparitions, witchcraft and occult folklore.
Excavations for a new underground station uncover a missile or a spaceship, and eventually reveals its huge locust-like occupants . Professor Quatermass (Andrew Kier) leads the scientific exploration of the site, bringing him into conflict with civilian and military Government.
Analysis, and research into parish archives leads to the discovery of... well a thrilling and audacious twist! Kneale had a special imagination and he delivers a knockout story/allegory. Its theory of a fundamentally divided humanity seems more prescient than ever. And gets ripped off all the time.
A measured, compelling and escalating nightmare of biology, engineering, politics, militarism and folklore.
