I frefer, of course, to the 2005 movie, not the 1933 original. It’s clear that Fay Wray’s version is simply terrified of the greatest ape of all. Naomi Watt’s version, on the other hand, though initially of the same mind, in the end tries actively (if hopelessly) to save him, and grieves for him once he dies.
The question before us, of course, is why. I have my own thoughts, but I’ll wait to see if the thread gets any traction.
