Unseen since its first transmission on ITV in 1965, this vintage six-part Rediffusion sci-fi serial will delight aficionados of the glorious golden age of British television drama.

A mysterious mass – known only as Object Z – hurtles through space, threatening earth with destruction. As society erupts into riotous panic and extremist political factions attempt to snatch control, the world’s nations must unite to find a solution in the face of Armageddon. Television producer Peter Barry (Trevor Bannister) and assistant Diana Winters (Celia Bannerman) become embroiled in the race to find answers – but time is running out.

Hard-hitting and contemporary, Rediffusion’s progressive programming for teatime viewers challenged the traditional dominance of BBC television in the 1960s. The cataclysmic world-under-threat sci-fi of Object Z will appeal to anyone who thrilled to Nigel Kneale’s The Quatermass Experiment.
