@socketwench - One of the wierd things about this movie is how close it hews to the original Pierre Boule book "Monkey Planet."

EXCEPT, the apes and humans are reversed. There are even parts of the movie where they lifted scenes directly from the book.

I do love this movie. The 60/70s Planet of the Apes movies are incredibly dire, and are movies I like to watch when I WANT Humanity to burn. This one is still dire, but is at least a lot of fun getting there.
