Question about the helmets and uniforms on board the Graf Spee (Salem)
My dad and I were talking about this film and I noticed that the German crew of the Graf Spee in the film are wearing U.S. Navy helmets. My dad mentioned that this was because of concerns by the real life U.S. Navy about displaying the swastika or other National Socialist symbols on board a U.S. ship and this is confirmed by Wikipedia.
Understandable, though confusing, because you see the correct period German helmets being used elsewhere in the film. However, it does seem strange that they'd go to those lengths to refuse use of the German helmets, yet permit other German uniforms to be worn on board the Salem, let alone the entire idea of casting the Salem itself to play the part of a German warship. And I'm pretty sure the uniforms displayed the swastika about as prominently, if not more so, than the helmets. Anyone have any other insight about this strange requirement during the filming? Is it just a result of sailors being superstitious?
