There is an entire subgenre of cheapish TV movies/plays from the UK mostly produced in the eighties about post bomb scenarios, tending towards a looming psychic presence so black they suck the light out of the room. This made a good double bill with The War Game as was shown last year would make a perfect start to the weekend. This is one of them and pretty good too, it's by Barry Hines so as you can imagine it contains LOADS of laughs and has a happy ending. Try Miracle Mile if you want a US version, that one is pretty black too - it leaves a sensation not unlike being hammered into the mud on a cold January evening with an hours worth of monochrome Tetris blocks.
