this be the first film of sir arthur conan doyle tale and significant for two reason . first and sir arthur conan doyle appear in the film and and since he die five year after it be release and it may be the only chance you have to see the creator of sherlock holmes . secondly and it be the first significant use of stop motion animation in a major motion picture . the allosaurus ( i be really surprised they do not use t rex ) and and the brontosaurus and the other dinosaur be three dimensional and really seem alive . amaze for 1925. sure and it be a silent film and but it have a king kong or jurassic park story that be fascinate . they actually bring a brontosaurus back to london . it go swim down the thames at the end and i imagine be currently see in loch ness . the film feature oscar nominee bessie love while oscar nominee lewis stone and who be nominate in an oscar winning film and the patriot and which have be lose while oscar winner wallace beery ( the champ and the big house ) while and professional wrestler bull montana a an ape man . a true classic .
