Quatermass

X the Unknown

A primordial radioactive mud creature threatens the Scottish countryside in Hammer’s taut and atmospheric 1956 Quatermass knockoff. As a film it is a footnote, but notable for gathering the Hammer Horror roster. 6/10

The Quatermass Experiment

Hugely influential, BBC’s 1953 mini-series about an alien virus mutating their hosts was a massive British TV event. Aired live, its sets were clunky and the acting stiff, but the great script and innovative direction overcome the flaws even today. 6/10
