There's a story behind this movie I'm sure, like why is it basically two movies, one with Kinski and one with Keitel, cause it makes no sense for the story and just makes it absurdly convoluted. I'd guess they had to replace Kinski and rewrote a bit to fit in a new hunter. There's also a ton of nature stock footage to bulk out the running time and some hastily tacked on animal rights stuff.
