The initial American release had many cuts made to avoid upsetting some special interest groups. the running time was cut from 123 minutes to 104 minutes. Most of the submarine's voyage up to Hudson Bay was removed. They dive after sinking the freighter (and filming her crew) and we next see them in the Bay, preparing to send the raiding party ashore. All the scenes of them entering the Bay, including the reference to "his charts" (the missionary's), were cut. They cut all references to the "flying missionary" who was a German spy, the scenes with the map and all of it. They also cut the other "delicate" passage there, where Hirth tells the captive Canadians that the Eskimos are sub-apes like Negroes, only one step above the Jews, and the ripostes from Johnnie and the Factor. Obviously they didn't want to offend southern segregationists or anti-Semites by showing that Nazis shared their racist views, or leave in any dialogue decrying same.
