Released in 1925 by First National Pictures, Willis OBriens The Lost World was a remarkably faithful adaptation of Arthur Conan Doyles book and served as a direct inspiration for the 1931 film classic King Kong (1933). Its story depended as much on OBriens pioneering special effects as it did on acting or directing. Film historians have long noted the movies impact on a generation of horror and fantasy directors and its continued impact on special effects. Today the film only exists in a greatly abridged version, with nearly half of the original footage missing. Through the original shooting script, the reader is able to reconstruct the "lost" scenes, imagining OBriens special effects genius. The editor also provides background information on the films production. Many stills of the movie are included.Kinnard, Roy is the author of '"Lost World" of Willis O'Brien The Original Shooting Script of the 1925 Landmark Special Effects Dinosaur Film With Photographs' with ISBN 9780899508610 and ISBN 0899508618.
