I know that they are on the brink of nuclear war with Russia, but why is every crew member's face in a constant state of perspiration? They are all sweating profusely throughout the entire movie. Except for Denzel and Hackman--they keep their cool. Is there no ventilation on those submarines? Is the temperature kept at a moderate 85 degrees?
Furthermore, let me ask everyone what they would have done in that situation. That is, you've been ordered to fire nuclear missiles at Russia. Then you get attacked by a Russian submarine, but before your radio gets severed, you get a message regarding your orders; but you don't know what the message is, because it got cut off during the attack. Do you try and re-establish communications and find out what the message says, or do you go ahead with launching your nuclear missiles relying on your last confirmed orders?
