Finally got a hold of Quatermass 2 the TV Series by Nigel Kneale and the movie The Quatermas Xperiment -both produced in 1955.
Still looking for the first tv series- The Quatermass Experiment and the third series- Quatermass and the Pit.
The movie below was my introduction to Quatermass. Still stands up -fantastic story. Another plus point is that it also stars the beautiful Barbara Shelly. Just look at that poster!
Brit Science fiction at its best.
