Corrected entry: In the scene where Ender is promoted to the Salamander Team, the Commander is pitching the baseball that is then caught by Ender. A conversation ensues and then the Commander enters the scene from a different corridor.
Corrected entry: The final battle against the Formics is a real battle, not a simulation. So how come Ender can see the battle through dynamic, controllable camera angles? In the early simulations this made sense because, well, they're simulations. But in the final battle there's no way to get those views.
Corrected entry: The movie attempts to be realistic about everything in space. And it's their first experience in zero gravity yet somehow they line up in perfect formation without any way of controlling their motion. Did they have some sort of jet-pack or propelling device? They get scolded for looking like drunken ducks and yet they are able to control themselves in zero g as if by magic.
