Director Doug Wildey ran up against NBC's "Emulative Clause," which stated that something from an animated series needed to be eliminated if a six year old child could physically emulate what he sees on the cartoon. This meant he could not equip apes with machine guns or knives or clubs or pistols or hand grenades, and that while the apes could wear rifles, they could not use them. Finally, Wildey asked if it would be okay to use Howitzers. The network agreed that they could not think of a way a six year old could operate a Howitzer so Wildey loaded the series with the weapon.
Austin Stoker (Jeff Allen) previously played MacDonald in La Bataille de la planète des singes (1973).
Henry Corden, who did the voiceover in the opening credits and voiced General Urko, was the second voice of Fred Flintstone. He took over when the original actor, Alan Reed, died in 1977.
The series takes place in 3979.
Shortly after this series went off the air, three paperback novels were released, consisting of adult-oriented versions of most of the show's scripts: 1) Visions From Nowhere ("Flames of Doom", "Escape From Ape City", "The Unearthly Prophecy" - with a cover photo of Aldo and his followers from Battle for the Planet of the Apes (1973)), 2) Escape From Terror Lagoon ("Tunnel of Fear", "Lagoon of Peril", "Terror on Ice Mountain" - with a cover photo of Urko and Zaius from the 1974 TV series), 3) Man, The Hunted Animal ("River of Flames", "Screaming Wings", "Trail to the Unknown" - with a cover photo of Zaius, Galen, and Urko from the 1974 TV series).
