Factual error: Apparently, Captain Nemo's submarine, Nautilus, is a shape-shifter. When it first surfaces next to the dock, it appears to rise easily 100 feet above the water, and that's only the visible part of the submarine; the bulk of the craft is still below the surface. This suggests that the water is a good 300 feet deep or more right off the dock, which is impossible. At this enormous size, it's also impossible that the Nautilus negotiates inland waterways, as when she goes to Mongolia. Strangely, we also see an overhead shot in which the Nautilus appears to rise only about 40 feet above the surface (compared to three-storey buildings directly adjacent).
