The Hunt for Red October (1990)
Funny thing is that this came out the same year as Kryptos. It’s fun and worth watching if you haven’t already seen it. The CIA element is just a sort of back-story for Clancy’s Jack Ryan and has little bearing on the actual movie. Now in real life though with the K-129 and attempted retrieval with the Glomar Explorer? That was a little more CIA. This movie was mostly tension and suspense, not a whole lot of intelligence per se besides the fact that he’s an analyst.
Kryptos moment: Just the timing and cold war.
Notable moment: When the global and nuanced conflict between two super-powers that defined a generation devolves into a bromance between Alec Baldwin and Sean Connery.
