Episode 6 of the 1976 Wonder Woman TV show was entitled "Wonder Woman vs. Gargantua" and featured a gorilla named, appropriately enough, Gargantua. The costume was by Donfeld. The Gargantua makeup is obviously based on the same John Chambers prosthetics created for Planet of the Apes. That's in contrast to most TV apes before then, which usually consisted of full-head masks.

Throughout the episode, the makeup details varied, depending on lighting and the day of shooting, but in several scenes, the face is almost identical to one of the Apes gorillas. In captures 5 and 6, you can even see the actor's non-blacked-out teeth in the open mouth. Note the changes in the size of his head, too.

A tenuous Apes tie-in, but very cool nonetheless.

Gargantua was played by Mickey Morton, who also played Chewbacca's wife 'Malla' Mallatobuck in The Star Wars Holiday Special and Kloog in the Star Trek episode "The Gamesters of Triskelion."
