"All irregularities will be handled by the forces controlling each dimension. Transuranic heavy elements may not be used where there is life. Medium atomic weights are available: Gold, Lead, Copper, Jet, Diamond, Radium, Sapphire, Silver and Steel. Sapphire and Steel have been assigned!"

This cryptic introduction sets the tone for an eerie blend of science fiction and supernatural mystery. It hints at a cosmic bureaucracy of elemental agents tasked with maintaining the integrity of time and reality — without ever fully explaining how or why.

In this hauntingly nostalgic episode of Very British Futures, Gareth Preston is joined by Steve Exton and Mark Stalker to unravel the enigmatic threads of ITV’s cult classic Sapphire and Steel. Together, they dive into the eerie corridors of time where logic bends, reality fractures, and two elemental agents—played by Joanna Lumley and David McCallum—battle forces beyond comprehension. They even engage in some genuine discussion of the periodic table and its metals.

Expect spirited debate, affectionate critique, and deep dives into the show’s surreal storytelling, minimalist production, and its place in the pantheon of British sci-fi. Whether you're a longtime fan or a curious newcomer, this episode will leave you pondering: just what is time… and who’s really keeping it in check?

Very British Futures is hosted and produced by Gareth Preston, with guests Simon Exton of The Extonmoss Experiment and introducing Mark Stalker.
