I'm not sure if it was a movie but there were 2 parts each hour and a half long and it was called "The Battle of Hood and Bismarck" it was on the history channel. One of the greatest ship battles in history when the pride and joy of both the german and british fleets Hood and Bismarck are sunk (Hood was sunk by Bismark and Bismark was crippled and sunk by Swordfish torpedo bombers, battleships and cruisers. 60 years after world war 2 a special team searches for both ships to get the first footage ever of Hood and to be the second to find Bismarck. Ask if you want to know more.
