Factual error: When Jack Ryan is chasing the Cook's Assistant Igor Loginov through the missile compartment, the compartment shown does not exist. Russian Typhoon submarines (of which the Red October is a variant, just with a new propulsion system) have a pair of cylindrical pressure hulls - each containing a missile compartment - on either side of the missile tubes. The location where the fight takes place in the movie would be inside a free-flood area in a real Typhoon. (02:01:20 - 02:05:00)
