Add to your list the British entry “Threads.”
I saw Special Bulletin a few years ago. Heard about it when it came out. Biggest interest I had was that it was set just a few miles from me in Charleston, SC.
When all of these came out I was in the USAF in SAC. BTW when home video became popular every B-52 crewman was expected to have their own copy of “Dr. Strangelove.”
Two things I remembered from Threads: One was the woman wetting herself as she looked up and saw the mushroom cloud, t'other was a 100 years later schoolroom scene and the irony of a teacher showing the children skeletons of animals - as if they hadn't seen hundreds - human and otherwise.
"Dr. Strangelove" - Besides Sterling Hayden's bravura performance, the biggest thing I remember was thinking that if the bomber could receive a call-back code, it could also receive a signal to blow up the plane. I'll bet each one of ours had a self-destruct charge for just such a case.
