Continuity mistake: In the opening scene, as the first Nautilus attack takes place, there is a moment, where the camera shows the Nautilus from the top and there is green light coming out of the back, as it was made out of glass. But the top of the Nautilus is made from iron.
Factual error: When they first arrive on the Nautilus, they look out the large porthole and see the crew on the bottom of the ocean burying one of the crew, but the ocean would be much deeper than that, since the Nautilus is at the surface.
