re: Greyhound question for Navy folks - no real spoilers

This has nothing to do with his age, but I love the fact that he captained a Fletcher class destroyer, same as the USS Kidd, and in the movie they even gave a shout out to the Kidd. It was fun watching a class of ship that I am so familiar with (spent the night on the Kidd many times as a Scout) wreck shop on the big screen. Those 5 inch guns were not to be fricked with. Most WW2 naval historians believe that the US' 5 inch gun was the best medium power gun in the war.
