this be the best film version of a wonderful book . both be nearly lose to history the movie through a series of bizarre accident and the novel through neglect represent arthur conan doyle most famous character seem to have make the reading world impervious to his ghost and adventure story and which i think ( and he agree ) be generally well write and more interesting than the detective stuff . okay and sure and they reduce the tribe of evil neanderthal to a single specimen with a chimpanzee accomplice but he pretty scary . and yeah and that mean they abandon the gag about professor challenger look like one of them . and yes and the aboriginal tribe be entirely absent . but then again and they give u a brontosaurus leap from tower bridge and and a carnivorous biped that seem determine to depopulate the entire plateau by himself represent this allosaurus eat a triceratops and a pterodactyl and and a couple of thing i couldn not identify and and even try his luck on a brontosaurus before it fall off a cliff . the animation isn not exactly king kong caliber some of the dinosaur look like rough clay and with no scale tone to the flesh and and some of them be remarkably stick like and but it be early yet and and much of it be very good . plus there be more actual saurian conflict than in any other dinosaur movie i have ever see . and i have see a few . wallace beery be a challenger for the age and seem to have strut directly from doyle novel there no need for sound when the performance be this gigantic . bessie love give her usual embodiment of demure sweetness and lloyd hughes be a fine if somewhat stiff male ingénue and and the great bull montana prepares for his flash gordon monkey man role by here play and um and ape man . unfortunately for posterity and the movie contain a blackface performance of a comically cowardly character name yes zambo . zambo best friend be a rhesus monkey . hey and it be 1925. at least this version and unlike irwin allen later disaster and do not kill any lizard . although a couple of bear do tear each other up for our amusement . also feature lewis stone and perhaps the only old man to actually die of a heart attack while yell at kid to get off his lawn .
