Not really a submarine movie, but I thought this looked good...a film commemorating the response to the "Fort Mercer" and "Pendleton" breakup in 1952...particularly, the legendary small boat rescue that saved the men on the stern of the "Pendleton".
Was pleasantly surprised to see that the boats/ships look historically correct - I can't stand it when Hollywood uses vessels from the wrong era, or that look like toy boats! From what I saw in the trailer, "Pendleton" really looks like "Pendleton".
