The Planet of the Apes cartoon starts on August 6, 1976.
I did not know about this series until recently. It is slow, but the constant zooms and pans make it feel a little more frenetic than it is.
The art is good, the animation is not fantastic. The voice acting is a bit bored.
If you're a fan of Doug Wildey and his original Jonny Quest series, the art here is Wildey-infused. He worked as "Supervising Director and Associate Producer" on the series.
