The Hunt for Red October (1990)

In John McTiernan's action spy-thriller set in the mid-1980s late Cold War era - an adaptation of Tom Clancy's novel:

• the memorable performances of over-the-top, magnanimous, pompous, rogue Soviet submarine Captain Marko Ramius (Sean Connery), a defecting naval commander of the prototype Russian nuclear submarine Red October, and his cynical hard-nosed American counterpart Commander Bart Mancuso (Scott Glenn) of the USS Dallas, commissioned to intercept the Russian sub (and its commander) and determine its motivations
• the early scene of the main protagonist - American CIA analyst and book author Jack Ryan (Alec Baldwin), briefing US government officials and military personnel on the threat of the Red October, and his tantalizingly bold prediction that Capt. Ramius was not insane or on the attack, but was motivated to defect and seek asylum in the US: ("I was just thinking that perhaps there's another possibility we might consider. Ramius might be trying to defect")
• Ryan's plan - with only a few days to spare - was to get in contact with and rendezvous with the vessel: ("We definitely grab the boat, sir...Maybe it's enough then to just get some people onboard to inspect it. Call it whatever you want to - a Coastguard safety inspection...Well, first, we need to contact the commanders in the Atlantic directly. If the Russians get one whiff of this through the regular communications circuits, the game is up. Second, we need to figure out what can we do to help them. We need to devise a plan to intercede - ready to go at a moment's notice. And third, somebody's gonna go out there and make contact with Ramius and find out what his intentions really are")
• the thrilling action sequences including Ryan's perilous helicopter-to-submarine transfer into the Red October to prove his theory
• the sequence of Ramius' first officer Vasily Borodin (Sam Neill) describing his dream of life in America to Ramius: ("Good, then I will live in Montana and I will marry a round American woman and raise rabbits. And she will cook them for me. And I will have a pickup truck or possibly even a recreational vehicle and drive from state to state...Well then, in winter, I will live in Arizona. I think I will need two wives")
• the stunning gunfight set within the bowels of the Red October, among towering red pumps, between saboteur-cook Igor Loginov (Tomas Arana) and Ryan - and Ryan's firing on Loginov to kill him

Ryan's Gunfight With Saboteur Loginov	Captain Tupolev (Stellan Skarsgård)	First Mate: "You arrogant ass! You've killed us!"

• the death scene of the opposing Soviet attack submarine V. K. Konovalov and its Captain Tupolev (Stellan Skarsgård) and crew by their own fired torpedo during diversionary tactics (a game of chicken with Capt. Mancuso) with the Soviet Captain's first mate growling back: "You arrogant ass! You've killed us!"

• the closing exchange on the Red October between Ramius and Ryan, who had navigated the vessel to a blue-lit river in New England (Maine), where they spoke about the aftermath: (Ramius: "Maybe some good will come from it. A little revolution now and then is a healthy thing, don't you think? Do you still like to fish, Ryan?...There's a river not unlike this one near Vilnius where my grandfather taught me to fish. 'And the sea will grant each man new hope. As sleep brings dreams of home.' Christopher Columbus"; Ryan: "Welcome to the New World, sir")
