The Lost World is a 1925 silent film adaptation of Arthur Conan Doyle’s 1912 book of the same name. The movie stars Wallace Beery as Professor Challenger. This version was directed by Harry O. Hoyt and featured pioneering stop motion special effects by Willis O’Brien (an invaluable warm up for his work on the original King Kong directed by Merian C. Cooper and Ernest B. Schoedsack). Writer Doyle appears in a frontspiece to the film. In 1998, the film was deemed “culturally, historically or aesthetically significant” by the Library of Congress and selected for preservation in the United States National Film Registry.
