The Lost World (1925)
Here's the original claymation dinosaur movie. A group of explorers find a plateau with relict populations of dinosaurs and ape-men. Doyle stayed hip to the latest research and, as Victorian sensationalists go, was pretty accurate about his animals. He's best known as the creator of Sherlock Holmes, but also wrote tales about a cave bear, a jaguar, a gigantic python, and a venomous snake trained to kill. Yes, I said he was accurate by Victorian standards, but that isn't saying much. A modern biologist would scoff at the idea of gigantic animals surviving on a plateau, because giants don't usually do well in isolated geography.
Anyway, Doyle didn't make the film, he only wrote the book. And the filmmakers weren't too invested in this accuracy stuff. Animator Willis O'Brien, however, has a fine eye for the motions of animals.
Attack Quotient: High. Lots of dinosaurs, plus some ape-man action.
Cheese Factor: Also high.
