Revealing mistake: When Eugene receives his return orders, not only is it from the wrong Roosevelt, but above the Eagle, it says the "State" of Washington rather than being from Washington DC, which is not a state. (01:08:16)
Revealing mistake: After Mr. Haengrang and Ms. Haman are shot by the Japanese soldiers, there are visible blood stains on their clothing from the wounds they would have sustained. But there are no bullet holes shown on the blooded part of their clothing, which is where the bullets would have hit. (01:17:49)
Revealing mistake: When Ms. Haman is shot by the soldiers, the moment that the gunshot that hits her is heard, and she is shot, there is already a massive, thick blood stain on her dress from where she is bleeding from. No gunshot wound on the planet can create an amount of blood that massive or thick in an instant. The blood stain was likely applied to her dress before filming the shot. (01:17:52)
