Screams from the Stokers
The most awful moment in the movie when Ericson can hear the screams as his men are trying to escape the flooding compartments. And then later on the Bridge, when from nowhere he has a flashback and hears them again on a clear and sunny day. Really sobering whenever I watch it.
PS I am in the Mob right now and they STILL use this film at Dartmouth College for training purposes. It comes on and it's in black and white and everyone laughs to begin with, but NOBODY'S laughing when that bit comes up or when they depth-charge the merchantmen. I've got a lot of time for this movie! And of course, the book is excellent as well. You can tell Noel Coward never served in WW2 by comparing this gritty piece of work to the fantasy propaganda piece that is "In which we serve". John Mills - "Gor Blimey guv'nor, the bosch gorn and shot me in me leg! It don't half smart!"
Alright, that's not an exact quote, but you get my drift.
