Astronauts Judy Franklin, Bill Hudson, and Jeff Allen find themselves stranded on a strange planet, but quickly learn that the planet isn’t alien at all. Flung into the future, the astronauts discover they are on Earth…but an Earth ruled by apes! With Judy being taken by a group called the Underdwellers and Will and Jeff fighting for survival among the humanoids with the help of a woman called Nova, things seem grim. Scientists Zira and Cornelius discover intelligence among the humanoids and begin a clandestine alliance with Will and Jeff in the fight to bring peace to Ape City.
Return to the Planet of the Apes was a science-fiction animated TV following the Planet of the Apes film series and live-action TV series. Largely based on Pierre Boulle 1963 novel, the series aired on Saturday Mornings on NBC from September 6, 1975 to November 29, 1975 and has gained a cult following since its release.
I grew up watching the Planet of the Apes movies, but really didn’t get to see the live action TV show or cartoon because they weren’t rerun with the frequency of the films. With streaming and DVDs, they are a bit more widely available if you seek them out, and Return to the Planet of the Apes is one of the series that is worth seeking out.
The story has continuing plotlines which is a bit unusual for cartoons at the time. Most Saturday morning cartoons were self-contained, but Planet of the Apes required the series to be aired in order…it would introduce characters and specific storylines that had to be followed. Stories like Judy’s adventure with the Underdwellers (and being called Usa aka U.S.A.) factor into episodes throughout the season while the theft of General Urko’s plane becomes a running dispute between Urko (voiced by second Fred Flintstone voice actor Henry Corden), Doctor Zaius, and the humans. It required a lot more patients from viewers than was accepted (and even possible) in 1975 with no VCRs even to keep up with a show.
This was the benefit and the curse of the show. The show was originally planned for three seasons with a complete story arc for the characters…this of course didn’t happen. You end up with an incomplete story though it is complete enough that you don’t feel slighted by watching it. It would have been nice however to see the whole story play out and see if Judy, Jeff, and Bill (and later Brent) would make it back home.
Another strange thing about the series is how uneven it is for the age it is targeting. The acceptance that cartoons were not “just for kids” wasn’t always the case and especially on the Saturday Morning front when the series aired. The show has typical killer creatures and big apes battling which is for kids, but it is mixed with more adult stories of politics and an ape political battle between science and war…which still feels oddly relevant. It also mixes in jokes like “The Apefather” and “William Apespeare” which are much more for adults than children.

Ma’am, can you say with certainty that you saw Barney Rubble take the Fruity Pebbles I left out for Santa?
The animation is both slick and at points obviously cheap. The classy art is largely designed by Jonny Quest artist Doug Wildey and has a certain charm. While it could be seen as cheap, there is also a strange “pop art” style to it that feels unique. With the use of the book as the basis, the apes are much more advanced than the film apes and generally live like modern humans in a city that resembles humans…with of course ape characteristics. The series often feels like it is forced to use filler moments to pad out its runtime with unnaturally long extended scenes of “suspense” (that generally aren’t that suspenseful) that pretty much involves switching back and forth between two of the animations over and over again…it becomes almost funny at points.
Return to the Planet of the Apes is a smart series that was too smart for the time. If it had been released now with streaming services like Netflix, Hulu, Amazon, and others, it probably would have made its three year run and would have been better received (it also would likely be buried amongst all the other streaming cartoons). Instead, the cartoon ends up a bit of an oddity and somewhat of a kitschy throwback to a different time that fans of the films should track down. As always, the Apes rule!
