Additonal comments from a_film by:
Incidentally, I remember reading that gorilla penises average around an inch or an inch and a half; if Jackson's anatomically correct Kong at twenty-five feet is four times the size of a six-foot man, his schlong's going to be four, six inches, tops. He's not going to impress anyone watching him on the big screen. Except maybe Tom Cruise.
As I wrote in the article the '33 Kong I don't really consider a gorilla--more a cross between a gorilla, a demonic anthropoid, and the accumulation of the filmmakers' pulp nightmares. So if he has a two-foot male organ, I'm perfectly willing to buy that; he's more of a sexual threat to Fay Wray than he is to Naomi Watts, who considers him A Beautiful Soul (up volume the sound of a plaintive violin).
Strangely enough, the version that does fullest (if still inadequate) justice to the natives is the '76 version: it at least had a scene where Jeff Bridges tells us the natives will miss Kong--he was their source of mystery and grandeur. That went a long way in explaining why they did what they did, even gave a psychological dimension to their collective character.
I don't like the '76 version much, but I do like that cast much better--Lange's blonde, Bridges' sub Kong, even Grodin's oil executive has more scale and megalomania than Black's clueless filmmaker.
