This slapdash version of the famed story follows its plot line fairly closely, save for some updating involving radiation poisoning in order to work in the popular nuclear element. Civil war survivors balloon to an uncharted island where they are assisted by Captain Nemo (Sharif), the only
box-office draw in the credits. He rescues them from a pirate attack, but remains behind when they leave the island, which is threatened by volcanic activity. The undersea creatures appear to have more life in them than the human characters in this strangely wooden production.
