In the BBC TV play Threads, broadcast on 23 September 1984, the nuclear bomb that drops on Sheffield is something of a social leveller. Mr Kemp, an out-of-work steelworker, is badly burned in his terrace house and his young children are killed outright. But there’s little to envy in the extra few days endured by the steelworks manager Mr Beckett and his family in the sturdy cellar of their large suburban semi. Just before the bomb falls, CND activists are rounded up. Police muscle into a demonstration and snatch a trade unionist calling for a general strike. Barry Hines’s screenplay was a response to Thatcher and Reagan’s economic policies as well as their nuclear brinkmanship.
