A haunting film about Britain and the nuclear age, from the first bomb tests to our potentially futile preparations for attack during the Cold War. Framed by Britain's mission to build the bomb, A British Guide to the End of the World uses extraordinary unseen archive and exclusive testimonies from people directly involved in our nuclear story, from conscripted soldiers attending the early nuclear tests in the South Pacific to servicemen, volunteers and civil servants involved in the planning of how we might have managed in the event of a nuclear catastrophe. Accompanied by an atmospheric score, the film features classified footage, hidden for decades, as well as television reports and government information videos that retain the spirit of Cold War paranoia. Horrifying, absurd and at times achingly poignant, the film recaptures a time of stockpiled paranoia that left a generation traumatised.
