20,000 Leagues Under the Sea

Factual error: The giant squid's tentacles aren't shaped like ones in the real world are.

Revealing mistake: In the scene near the end when water is filling up the submarine, Kirk Douglas begins fighting with a member of the crew to escape. As Douglas hits him his false sideburn falls off and flies across the screen.

Audio problem: During the "Whale of a Tail" scene, there are several instances when Kirk Douglas' hands are away from the guitar strings, to ring the bell or twirl the guitar, yet the sound of the guitar strumming continues without missing a beat.

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.

Revealing mistake: When the shark attacks the divers, it is very obvious the shark is a puppet.

Revealing mistake: Kirk Douglas' stunt double is obvious during the scene of Nemo trying to drown him and his friends as they hold on to the dorsal.

Continuity mistake: Before the Nautilus rams the munitions ship emerging from the harbor, there is a land mass on the Nautilus' starboard side. After the Nautilus attains collision speed, the oncoming shot of the Nautilus shows no land mass.

Revealing mistake: The close ups of Ned Land and Conseil in their diving gear as they discover the sunken treasure were obviously filmed on a sound stage - there are no bubbles emanating from their helmets as shown in other actual underwater scenes.

Audio problem: After the order "Beat to Quarters" is given, the Senior Petty Officer shouts orders, but no sound is heard from him. Further, the crew runs around shouting and no sound is heard from them.

Factual error: A squid does not propel itself at speed tentacles first, but head first.

Suggested correction: Cobblers. The first films of giant squid, captured in the Sea of Japan in 2013, show them doing just that. It's all about how they attack prey and the positioning of their eyes, but they can and do travel at speed tentacles first.

Quotes

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.

Trivia

The name of the supply colony that Nemo shows the professor is Rura Penthe, which is also the name of the Klingon prison in Star Trek VI.
