This is a formulaic Tarzan movie. You have your girl, natives, and even a jungle boy. You would think that it would be pretty lame, but it's not. If I had to guess, I would say that the people making this movie knew how formulaic it was and so they pulled no punches. It's a simple Tarzan story and that's the way it's presented.
First, the movie takes place in Africa. It doesn't try taking Tarzan to far off places. It's stays right in Tarzan's backyard.
Second, Mike Henry does a much better job in this one than any other one. It was like he finally figured out how he should play Tarzan.
Third, the boy, played by Steve Bond, does a really good job. He doesn't over act and is believable.
Fourth, the evil and good natives, who are brothers in real life and in the movie do a great job. They are fit and much like everyone else, they don't over do it.
Fifth, the girl, Aliza Gur, is very pretty and has your classic 60's look. Wearing the riding pants, boots, low cut top, long hair with the wide head band. She looks like she stepped off the set of the Beverly Hillbillies.
So if you want a simple Tarzan movie that you can get into, this one will definitely work.
