I never knew this had been made. Intro. by Walter Cronkite and first broadcast LIVE!!!!! on CBS as, effectively, a stage play in 2000. Absolutely outstanding production. Ironically, I first came across the novel "FailSafe" in the Corps modest little library at Innset in Northern Norway about thirty years ago where we trained to stop the Russkies, etc. etc.....
Also, the original 1964 film directed by Sidney Lummet and starring Henry Fonda as the President.

Neither make cheerful viewing but are both completely gripping.
