The Phantom Submarine U-67 (MOD) (DVD Movie)

U.S. Navy captain Greg Winters chases a German U-boat when it torpedoes the Alatania, a merchant vessel crossing the Atlantic. Winters disobeys orders, pausing to search for survivors, and loses track of the submarine. A subsequent court-martial relieves him of command. Years later, he encounters sub captain Karl Ludwig again when the two men are hired to retrieve a safe that went down with the Alatania. A swarm of unsavory characters are anxious to get what's inside the sunken safe - a document worth millions.

Character actor Alan Hale is best known for playing Little John in The Adventures of Robin Hood (1938) with Errol Flynn. He had the same role in the 1922 silent version of Robin Hood with Douglas Fairbanks and then once again in 1950 in Rogues of Sherwood Forest.
