The Sea Wolves (1980)

They were the unlikeliest heroes of World War II - the gray-haired veterans of the Calcutta Light Horse, who hadn't seen action since the Boer War, but were fated to become The Sea Wolves. Retelling of true wartime exploits hidden until the 1978 British Official Secrets Act lifted security restrictions. In 1943, German merchant vessels off neutral Goa (a Portugese colony on India's western coast) transmit information about Allied ships to a predatory U-boat. Unable to launch a raid in neutral waters, the British draft some "unofficial" commandos. Shot on location, The Sea Wolves is a grand all-star adventure that recalls The Guns of Navarone and The Dirty Dozen. Want excitement? You've got it!
