Cmdr. Ferraday: We operate on a first-name basis. My first name is Captain.
Cmdr. Ferraday: It wasn't sealing wax. It wasn't chewing gum. It was epoxy glue. And all of a sudden you know a whole damn lot about submarines.
David Jones: I know how to wreck them, and I know how to lie, steal, kidnap, counterfeit, suborn and kill. That's my job. I do it with great pride.
Boris Vaslov: They say - a bull in the ring dies a much better death, than a steer in a slaughterhouse. A bull has a chance.
1st Lt. Russell Walker: It's just... none of us have ever been aboard a submarine before.
Cmdr. Ferraday: Rest easy. I have.
Cmdr. Ferraday: I'm in command of this submarine, and I am not sticking another torpedo up that spout.
David Jones: May I ask, Captain, when we expect to reach the ice barrier?
Cmdr. Ferraday: Yes, you may ask.
David Jones: People with top security clearances are being hung everyday.
David Jones: ...and all of a sudden, you know a whole damn lot about my business.
Cmdr. Ferraday: We don't believe in going on a mission totally blindfolded.
