In addition to that there were several documentaries and TV dramas at the time about it around the time. The best that I remember was a Q.E.D. narrated by Ludovic Kennedy (IIRC) and Threads from 1984. They were the grimmest pieces of television I ever watched. Threads was on Youtube but it seems to have been removed.
The funniest piece about the aftermath of a nuclear war in the early 1980s was Jasper Carrot reading quotes from Protect and Survive, which was in response to a civil defence exercise that was taking place on the same day as the programme.
I haven't seen The Bed Sitting Room all the way through, but I thought one of Frank (Captain Peacock) Thornton's finest hours was him as the last survivor of the BBC reading the news whilst wearing a hollowed out TV set.
BTW I know that film was from the 1960s and therefore not strictly relevant. I tried to find Mr Thornton's scene in the film on Youtube too. However, typing Frank Thornton Bed Sitting Room in the Youtube search engine produces finds Amy Winehouse - In My Bed.
