Just finished 20,000 Leagues Under the Sea - Disney 1958
I find it a bit odd this movie came out the same time the USS Nautilus was built/launched and in the movie there was a reference to showing what is in essence a Nuclear Core.
Things that make you say Hmm.
Anyway, I had a major issue with one of the movies' concepts.
Nemos Island Lair had a base with a Satellite Dish, yet the movie takes place in 1887.
