Corrected entry: The dinosaur that rises from the lake is an apatosaurus (or something from the same family). Apatosaurus is herbivorous, and would never try to eat humans as depicted. Even if the species had changed its diet in the millions of years since its apparent decease, its body is not appropriate for hunting: too big, too bulky, too slow, etc.
Corrected entry: The scene where Kong peels off Ann's clothes was censored from the original release for being too racy, but it was later restored. Also, when the sailors are being rolled off the log bridge they were supposed to fall into a pit and be eaten by giant spiders, but the scene was removed because it tended to scare audiences into walking out of the theatre.
Corrected entry: When Kong falls, the girl is about a floor or two below the man, yet he has time to go get her and they both get down to the ground floor just about the same time as Kong. Who can move that fast?
Corrected entry: If the natives were so afraid of Kong (and the dinosaurs) that they built a fifty foot wall to keep him out, they never would have included a fifty foot tall door in it to give him access to their village.
Corrected entry: When Kong is approaching the platform containing the girl, in both the 1933 and 1976 versions of the film, he tears down many trees. Since the platform is there and does not appear new, and a large ape is likely to have a large appetite, we can assume the ape must visit the platform regularly, thus it is likely that all the trees around there would have been torn down already.
