Trivia: The dimitrodon, the dinosaur in the middle of the movie, is actually a real lizard (a basilisk, in fact) with a sail glued onto its back.
Trivia: A naggingly familiar quote that has been attributed on the Internet to various authors (ranging from Edgar Allen Poe to Henry Wadsworth Longfellow) is "Sleep. Those little slices of death. How I loathe them." Problem is, Poe never wrote any such thing, and neither did Longfellow. The 1987 horror film "Nightmare on Elm Street III" seems to be the genesis of the misquote, which it incorrectly attributes to Poe. So, where did the actual quote originate? The answer is Walter Reisch, lead screenwriter on the 1959 film "Journey to the Center of the Earth." In the screenplay, the antagonist Count Arne Saknussemm is urged to get some rest, to which he memorably replies, "I don't sleep. I hate those little slices of death."
