Nazi propaganda by the wartime censors. After the end  of World War II, the picture was finally released in Germany but with around  20 minutes of footage cut (all scenes with Major Strasser and all references  to Nazism). Other scenes were dubbed so that they had a totally different  meaning (Victor Laszlo became Victor Larsen, an atomic physicist). In the 70s  the film was redubbed by the ZDF, this time in its uncut form.
