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.

Continuity mistake: When Ned Land dives into the ocean to save Nemo from the giant squid, his knife is in his hand. After Ned reaches Nemo, he then draws the knife from its sheath.
Captain Nemo: Think of it. On the surface there is hunger and fear. Men still exercise unjust laws. They fight, tear one another to pieces. A mere few feet beneath the waves their reign ceases, their evil drowns. Here on the ocean floor is the only independence. Here I am free! Imagine what would happen if they controlled machines such as this submarine boat. Far better that they think there's a monster and hunt me with harpoons.

Question: What did Captain Nemo mean when he said, 'I found out what I wanted to know'?
Answer: To see what kind of men they are, especially Ned Glass. They held on to the sub against the harshness of the ocean. They did not scream, cry, or beg for mercy.
