1964 ... "Three Reactions to Shelter Life"

"One of the more bizarre, but perhaps more intriguing and realistic Civil Defense films of all time, "Three Reactions to Shelter Life" attempts to highlight the negative psychological reactions that people might experience, living in a fallout shelter following a devastating thermonuclear war.  These include aggression, regression, and of course depression. Released in 1964 by the Office of Civil Defense the film highlights the mental suffering likely to occur even when the occupants of a public fallout shelter remain physically safe.  Interestingly, Three Reactions to Shelter Life leaves each scenario unsolved, suggesting there can be no easy answers to the problems of human interaction.The subject of the film, and its content, seem right out of Rod Serling's "Twilight Zone".  - Internet Archive
