The movie. Heard it was "B" rated nonsense. Boat, water, bombs, smelly guys all beating impossible odds only to die in their own country at the end. Same old song and dance. Typical Hollywood formula. It's a joke and totally common place. I had no interest. I watched, "20 Leagues Under the Sea." Much better story. Believable. Top notch stuff.
Believe that and I'll tell you I have a bridge for sale. I have all versions of the movie. Das Boot is the very best movie about u-boat warfare that will never be matched. Shame the Pacific submarine service is not handled by Hollywood in the same manner. In short, I was just messing with ya.
