For the life of me, I can't understand why they would generate another fiction sub movie when the greatest sub story ever (in my humble, etc.) is TRUE and written as a great book. I'm speaking, of course, of "Clear the Bridge", by Richard O'Kane, the story of America's most successful WWII sub, the USS Tang.
The story has everything, from a crack, on-the-ball crew who push all the limits, to humor, to depth-chargings. There are some of the best rescue and sinking scores. There is the awful struggle with faulty torpedos, and a crew who dealt with them themselves. In the last battle of their last patrol before the boat was to go back to the states for a refit (and crew shake-up), their last torpedo malfunctions and sinks the sub. THEN, we read of the only case of survivors from a sub sunk in battle and their POW experience. This story has EVERYTHING.
READ IT, confound it. I've read just about all of them by now. Believe me, all the others pale by comparison.
Someone has GOT to make this into a movie!
