First aired on the BBC in 1953, Nigel Kneale’s The Quatermass Experiment can rightly lay claim to being the first original science-fiction serial on British television. Hammer’s quickly commissioned feature film version can equally lay claim to being the film that changed the fortunes and, indeed, the direction of Hammer’s future output, as the studio quickly skewed towards genre fare, becoming the prime British go-to for lurid gore-drenched horror films, reinventing the Universal rogues’ gallery of monsters for a new generation for well over a decade.
The retitled Quatermass Xperiment (known as The Creeping Unknown in the USA) and its sequel Quatermass II are sci-fi outliers for Hammer, but both films have their roots in the horror genre, especially this first film and its depiction of an extra-terrestrial intelligence that turns human flesh into living vegetable matter. This impressive and comprehensive new 5-disc box set presents the black-and-white film in a crisp, vibrant 4K transfer, along with a Blu-ray disc, complete with the surviving episodes from the original BBC serial and a wealth of supporting material, both old and new.
The Quatermass Xperiment is a simple story of grisly first contact. Bernard Quatermass of the British Rocket Group (here played by surly American actor Brian Donlevy – much to creator Kneale’s chagrin – rather than Reginald Tate, who played the role on TV) and his team rush to the scene when a spaceship launched by the Group with a crew of three astronauts crashes back down to Earth.
Two of the astronauts are missing, but their spacesuits are intact. Victor Carroon, the third astronaut (played with cadaverous unearthliness by Richard Wordsworth, great-great-grandson of poet William), is delirious and feverish. It soon becomes apparent that Quatermass’s rocket has brought something alien and potentially unstoppable back with it when Carroon escapes confinement and starts to become distinctly inhuman. The creature engulfing his humanity needs to feed on the life-force of anyone who gets in its way as it tries to find sanctuary so it can germinate and spread its spores across the world.
The script (written by Richard Landau and director Val Guest, as Kneale was precluded from contributing due to his contract with the BBC) nimbly truncates the TV serial’s six half-hours into a punchier 82 minutes. The story is still powerful and chilling, even if much of Kneale’s original subtlety and nuance is lost and the production inevitably looks like a product of its time.
Donlevy’s gruff and surly Quatermass must reluctantly work alongside Inspector Lomax (Jack Warner, already looking a good ten years beyond retirement age here, two years before he began a 21-year residency in the BBC’s Dixon of Dock Green). Both men wander through the film welded into their overcoats, Lomax initially sceptical about the threat posed by Carroon whilst Quatermass struggles to understand exactly what has become of the ailing astronaut and the danger he might pose to the human race.
There are some moments that chill even now – Carroon’s victims are turned into lifeless husks, and a scene where he causes carnage at London Zoo still has the potential to disturb animal lovers. The film retains the serial’s memorable Westminster Abbey climax, where the creature, now a mass of thrashing tentacles, lurks in the building’s rafters and scaffolding, but it abandons the more cerebral ending of the TV version by electrocuting the creature to death. Quatermass himself strides off into the night, promising to start his experiments again…
A masterpiece of low budget British sci-fi/horror, The Quatermass Xperiment is handsomely directed – Val Guest gives it his typical sense of realism, with characters often talking over one another or interrupting each other, and a generous amount of location filming in and around London. It’s almost as much a landmark of UK genre cinema as the original version was for TV sci-fi.
The lead characters are a little stodgy and Donlevy is about as far away from the modern idea of a film hero as it’s possible to get, but this is still a gritty, surprisingly creepy and graphic story that has itself influenced so many other TV series, writers and storytellers across the decades.
This chunky box set includes the film under its UK and US titles and a bounty of supporting material, including the first part of the Nigel Kneale story presented by lifelong superfan Toby Hadoke, a ‘making of’ documentary, new commentaries and archive material, as well as a colourful poster, an engrossing 180-page booklet, an examination of the life and career of Richard Wordsworth, art cards, and a reprint of the old House of Hammer comic strip adaptation which hasn’t seen the light of day since the 1970s. The shelves of no serious fan of sci-fi/horror – and Hammer in particular – is complete without this gorgeous limited edition release. A similar set for Quatermass II is imminent.
