Threads is such a quality TVM, hard watch, but well worth it!
Anyone who appreciates Threads should give 'When the Wind Blows' a watch.... It's a beautifully tragic nuclear holocaust cartoon. It was shown over here in the UK back in the 80s one evening over the Christmas holiday (totally inappropriate scheduling) and had a huge effect on me as a kid. Well worth a watch, can be found on youtube too, here;
