Revealing mistake: When the castaways discover two women and a man washed up on the beach, they quickly determine that the women are still alive. The journalist, Gideon Spilitt, checks the pulse of the male and pronounces him dead; but the dead man's limp left hand very noticeably and unnaturally jerks twice just as Spilitt releases his wrist. The actor playing the dead man obviously had an anticipatory reflex action, but they chose to keep the shot in the film, anyway.

Factual error: Captain Nemo takes the castaways on an underwater tour around the island, where they observe Greek temple ruins on the sea floor. The ancient Greeks were pioneers of philosophy, politics and engineering, but they never colonized beyond the general area of the Mediterranean and they certainly never colonized the South Pacific (which is the setting of Mysterious Island).
