this film really make me feel wistful . you see and the original version of this film be about 50 % long and i really would like to see what some idiots chose to remove from the original print . this be especially true for the very end and a the film end way too abruptly and it look like there must have be a lot more to this movie . a it be and the film be way too choppy and i will one day look for a more complete version . the movie be a masterpiece for 1920s stop motion photography . willis obrien and who later become famous for this type of film in 1933 king kong and be also the guy responsible for bring to life the dinosaur in this film . the overall effect really isn not that much different than a decade later a both film be wonderful for the time . sure and it possible to make them seem almost 100 % real today and but for the 20 and 30 and this be amaze stuff . the plot involve a crazed anthropologist ( wallace beery ) who insist that there be a land fill with living dinosaur in south america and he want to mount a return expedition to find a colleague who be strand there . though scoff at by other professor and he be able to get funding and convince others to come with him . once there and they find pretty much what you would expect they would find ( except that there be some african creature here as well oh and well and if they can have dinosaur and why not chimps . ) . the only surprise be that they bring back a live brontosaurus and it pretty much do a king kong type escape at the end and run amok in london and not new york . and and while all this doesn not seem very original and remember that king kong be second this be the first film of it type and so it deserve a lot of kudos and recognition for it place in film history .
