Best submarine movie ever made!
That's right if you even have a remote interest in what submarine crews had to endure or in WW2 naval warfare then this movie is it. You really see why the men fighting in the german U-boats had the highest manpower losses in proportiion to all the other german services in WW2.
You really feel the boredom of most of the cruise then followed by intense action, then the scary depth-charging. All in wonderful 5.1 english sound.
The finale of this movie is the boat having to make a dash through the straight of Gibralter into the mediterranean.
If you ever own a submarine movie this is the one to own!
Buy this and The Hunt For Red October for a pre and post nuclear sub collection. You will need no others.
