The Lost World (1925) -Dinosaurs Roar to Life in Silent Film History.
Prior to King Kong and Jurassic Park it was The Lost World (1925) – the first film version of the famous novel by Sir Arthur Conan Doyle, a pioneer in terms of special effects in the movie world. Under the direction of Harry O. Hoyt and with phenomenal stop-motion special effects by Willis O Brien, this silent adventure movie film contributed to the future art of fantasy and science fiction filmmaking.
📚 Plot Summary
Paula White, a missing father sketch-writer, takes the journal to Professor Challenger in London. The illustrations show alive dinosaurs, and Challenger states that prehistoric animals are still on the land, making him ridiculed. Supported by a newspaper, and accompanied by reporter Edward Malone, sportsman Sir John Roxton and skeptic Professor Summerlee, a crew sets off to an unknown plateau in Venezuela.
There they are met by rampaging dinosaurs, a violent ape-man and a volcanic eruption as they are trapped in a dangerous prehistoric world. The struggles take place among Allosaurus, Triceratops and Pteranodons, which came into existence as the result of the stop-motion expertise.
In the end, the crew succeeds in escaping, however, not before they take home a live Apatosaurus and bring him to London, where he breaks free and throws Tower Bridge into the river, disappearing forever.
