The Lost World (1925, dir. Harry O. Hoyt, adapted from Arthur Conan Doyle’s book), the silent fantasy epic that inspired King Kong, and ultimately Jurassic Park.
In the film, Professor Challenger (Wallace Beery) & his research team go on an expedition to authenticate his claims that a “lost world” of dinosaurs exists in the Brazilian jungle. Chaos, of the rampaging dinosaur variety, inevitably ensues.
The team members manage to escape the island, but like many science-fiction movie characters to come, they have the brilliant idea of bringing a member of the dangerous species they’ve discovered back home with them as some kind of ill-tempered, homicidal souvenir. Luckily, too, as this opens the door for the terrific sequence in which the brontosaurus escapes and runs amuck through the streets of London.
The film, the first live-action dinosaur adventure, is also notable for its groundbreaking special effects, courtesy of Willis O’Brien, the pioneering FX artist.
