The Region 1 DVD has certain graphic elements removed. Most notably, the view of the captain Lansing's cabin presents the captain's corpse being handcuffed to bulkhead and another corpse sitting by the desk. (Later the viewer learns it was an SS operative.) However, in the censored version only a glimpse of the captain Lansing's corpse is shown, the SS-man is totally cut out. This censorship severely interferes with the plot, as it is crucial to the novel to understand the motives of captain Lansing.
