Threads is a 1984 British-Australian apocalyptic war drama television film jointly produced by the BBC, Nine Network and Western-World Television Inc. Written by Barry Hines and directed and produced by Mick Jackson, it is a dramatic account of nuclear war and its effects in Britain, specifically on the city of Sheffield in Northern England.
Shot on a budget of £400,000, the film was the first of its kind to depict a nuclear winter. It has been called “a film which comes closest to representing the full horror of nuclear war and its aftermath, as well as the catastrophic impact that the event would have on human culture.
In the city of Sheffield, Ruth Beckett and Jimmy Kemp plan to marry after learning of Ruth’s unplanned pregnancy. The plot serves as a distraction to the viewer against the backdrop of a gradually escalating confrontation in Iran where a Soviet-backed coup has occurred. The United States mobilises its own forces and occupies the southern part of the country, and increases its naval presence in the Persian Gulf. The U.S. also deploys B-52 Stratofortress bombers to Turkey when it learns the Soviet Union has moved nuclear warheads into Mashad.
