After successfully adapting the three Quatermass television stories of the 1950s and with the box office tills ringing from the well-received cinema version of Quatermass and the Pit (1967), Hammer Films approached creator-writer Nigel 'Tom' Kneale for an original film script featuring the titular scientist with a view to continuing the franchise.
The studio announced another film but nothing developed beyond an outline and preliminary discussions with Kneale. Hammer had faced delays getting Quatermass and the Pit to the screen after their partnership with Columbia faltered and it was perhaps disinterest from distributors, Hammer's struggle to adapt to changing audience tastes and the slow decline of the industry as a whole that stalled their fourth Quatermass outing.
Kneale remained busy. His relationship with the BBC strengthened in the late 1960s and early 1970s and he succeeded in getting several key plays to the screen in this period. This was after he had refused overtures from the BBC to contribute a one-off drama to their Theatre 625 strand on BBC2. He felt he had never really been properly recompensed for the Quatermass serials he had made in the 1950s, something he made quite clear to the BBC's Director General Hugh Carleton Greene. A one off payment was duly agreed and Kneale undertook his new assignment. This would become 1968's celebrated play about television's Orwellian future potential, The Year of the Sex Olympics. (1)
He followed this with 1970's 'Wine of India' for The Wednesday Play, which centred on a 100-year old couple who must make plans for their funeral in a future where advances in medicine have resulted in a need for population control and where those reaching the age of 100 must submit to a government controlled euthanasia program. He contributed 'The Chopper' to Out of the Unknown in 1971, a ghost story about a dead motorcyclist haunting his wrecked machine, and followed this in 1972 with The Stone Tape, in which scientists researching new recording technologies at an old mansion investigate a haunting.
