Nigel Kneale, the serial's scriptwriter, remembered the BBC's blunt reaction to the ambitious sequence of a giant clump of alien algae inside Westminster Abbey. 'When (the BBC) realized there was a special effects sequence showing a monster in the sixth episode, they said to me, "Well we're not gonna do it! You wrote it, you do it!" '
Kneale and his future wife Judith Kerr made the monster themselves with some very DIY methods. They coated a pair of gloves in plants and other detritus, putting the gloves on and placing their hands in a hole cut in a blow-up photo of Westminster Abbey's interior.The camera would be facing the blow-up photo, and Kneale would wriggle his fingers while wearing the gloves, to simulate that the creature's tendrils were moving.
The cheap effects aside, Quatermass Experiment received large viewerships and critical praise, and various film companies attempted to buy the rights from the BBC to make a film adaptation. What drove all these companies away was that, if the serial was to be adapted faithfully - alien-induced warts and all - the resulting film would get an 'X' rating.
The one studio that did not balk at the prospective 'X' rating was Hammer Film Productions. Anthony Hinds, Hammer's owner, was so impressed with the serial that he had written to the BBC asking for the Quatermass rights before the serial's last episode was broadcast!Hammer was a fairly unknown studio that produced low-budget 'quota quickies' and Hinds realized that the 'X' rating (which a more prestigious studio would avoid) could be used as a marketing gimmick, hence the film adaptation's title of The Quatermass Xperiment
Hammer's commitment to the original serial's grisly tone (and that 'X' rating!) meant that the film would not shy away from body horror or graphic death. The transformation of Richard Wordsworth as the mutated astronaut Carroon was handled by makeup artist Phil Leakey.Leakey had previously only worked in 'straight makeup' duties; Quatermass Xperiment was his first foray into 'monster' makeups. Decades later, Leakey explained how he did the makeup. 'Richard remained in the hands of the makeup departmet for as long as he maintained humanoid form. (...) I had some discussions for the producer and director Val Guest, and we concluded that Richard should not look ugly - at least, not to start out with! Instead, he should look sad, ill...perhaps rather pitiful. After we all agreed on that, the rest was left up to me.
(The mutated arm makeup) was invented using simple items - corn flakes, rich, cotton wool, rubber and latex. We had no laboratory in the studio at that time, so I had to make everything at my home! The cactus-arm was a wrarparound piece made from rubber, cast from a plaster mold, which was attached to a lady's stocking so Richard could slip it on and off easily. Likewise, the handpiece was built onto a cotton glove.'
Leakey also made the corpse props of Carroon's victims, making a dessicated head prop and shrivelled hand props. The 'inhuman' monster scenes, along with the matte paintings and miniature shots, were handled by Les Bowie's fledgling effects company. I've not yet found any information as to how they achieved the shot where a 'remnant' of Carroon's mutated body slithers across the floor.Was it rubber mixed with cloth, or perhaps, like the main monster, tripe?
Quatermass Xperiment's finale utilized effects that while still primitive by today's standards, were still more sophisticated than the original serial's very DIY methods! Val Guest, the film's director, remembered how Carroon's final form was achieved.'There were quite a few attempts to construct the monster that appeared in the climax, and eventually it ended up being made mostly out of pieces of tripe, as well as rubber solution. That was all the work of Les Bowie, the special effects man. It was all shot in the special effects department'.
Producer Anthony Hinds recalled how miniatures and camera trickery were also used for the finale. 'We had no money in the budget for special effects. We built a little model of the roof with this scaffolding there—the Abbey was supposed to be being redecorated, and this monster was in the scaffolding. And we got some tripe, which we wound round this thing on an elastic band, and when we undid it and ran the camera backwards - or rather printed the film backwards - it coiled its tentacles.'The shots were the creature burns were done, according to Les Bowie himself, via 'some sparks and fireworks in the thing, and we made it react because we were using little wires and strings'. Sadly, in yet another example of old-school filmmaking's disregard for animal welfare, some close-up shots replaced the model with a real octopus that was set on fire.
Quatermass Xperiment was a commercial success, leading Hammer to immediately produce X the Unknown. X the Unknown was written as a Quatermass sequel proper, but was quickly retooled into an original film after Kneale vetoed Hammer's proposal.
X the Unknown once again had Phil Leakey and Les Bowie returning to do the makeups and special effects respectively. Leakey handled the grisly effect where a doctor is melted alive from exposure to radiation. Leakey explained the effect in Fangoria;'For that effect I built a spong rubber hand, and into the hand were set thin plastic tubes with perforations along their length. These tubes entered the forearm through the wrist to each finger, and all the ends were attached to a specially-adapted pump. At the director's signal, a special chemical mixture was pumped into the flaccid handpiece, which immediately began to swell up and discolor. It was quite a good effect.'
The shot of the hand swelling was accompanied by a melting wax head built up over an anatomy skull, with camera trickery used to make the melting appear quicker; at least thirty or so years before Raiders of the Lost Ark!Les Bowie's special effects were again a combination of matte paintings, miniatures and puppetry; I am not quite sure how the effect of the radioactive mud blob was achieved as of now; was it a rubber 'cloth' (also utilizing tripe?) with a light underneath?
Interestingly, a year before X the Unknown, the BBC had allowed Jack Kine and Bernard Wilkie to establish the BBC's Visual Effects Department, and the Department's first major workload was, of course, the BBC's own sequel Quatermass II.
Among the assorted miniature effects and spacesuit costumes, Kine and Wilkie also had to depict the alien blob writhing in the refinery's reactor. This was achieved cheaply, but effectively, as 'an empty tin, a toy ladder, Kine's hands in latex (gloves) and some dry ice'.When Hammer greenlit their own adaptation of Quatermass II, Bowie Films Ltd would return to handle the special effects. Bill Warrington overseen the miniature and creature effects, assisted by Henry Harris and Frank George.
At the film's finale, a set of giant alien blobs burst out the reactors and go on the rampage. The blobs were realized similarly to the Carroon mutant in Quatermass Xperiment; they were made from a mixture of rubber and tripe from a butchers, and shot in a miniature set.The extensive miniature filming under the studio lights caused the tripe to go off and stink, turning the shoot into a disgusting experience! Brian Johnson, part of the Bowie Films crew on Quatermass II, remembered that tripe was still being used for effects shots on Ridley Scott's Alien, but by then they cleaned it to prevent smelling!
