He is in "The Sea Chase", a 1955 World War II drama film starring John Wayne and Lana Turner. John Wayne, as Captain Karl Ehrlich, is determined to get his German freighter home during the first few months of the war while being chased by the British and Australian navy.
The brief opening shots of Sydney Harbour (not shown in the above trailer), before they had built the Opera House and even before the much maligned Blues Point Tower dominated the skyline of the North Shore, make this movie worth watching, even if it weren't for the fact that the story is based on the real 1929-built German Norddeutscher Lloyd steamer "Erlangen" which, under Captain Alfred Grams' command, slipped out of New Zealand's Lyttelton Harbour on the very eve of war.
The pursuing British and Australians had the navies that ruled the waves but the Germans had the Duke! Pity it was just in the movies ☺
