While The King Kong Show is mostly remembered nowadays as the source material for King Kong Escapes, it’s a significant historical milestone for being the first case on an American TV show getting animated in Japan. The program, while nominally a Rankin-Bass production, has its share of anime cred, featuring direction by Yugo Serikawa (Cyborg 009), music by Asei Kobayashi (responsible for the the Gatchaman, Lion Maru, and Turn A Gundam themes) in addition to Rankin-Bass staple Maury Laws, and planning by Yoshifumi Hatano (Cyborg 009, Saint Seiya).
While the general plot featured a softer Kong who befriends a young boy (which set the template for every Kong animated series to follow), monster fans have no shortage of excitement in the series as the title character battles aliens, robots, and mythological figures in addition to the traditional prehistoric animals from the movies, and each episode is two stories, separated by an episode of Tom of T.H.U.M.B., so any given story only runs about 7 minutes. Yeah, usually I skip over those middle segments.
Unfortunately, of the 26 episodes, Classic Media has only released the first 8 on DVD. This does not include the introduction of Mechanikong, though that episode is pretty widely circulated in bootleg circles for its movie tie in. Personally, I’m much more interested in watching Kong fight a robotic statue of liberty! Hopefully a complete series box materializes at some point, but if they’re not doing so to cash in on Skull Island, I have no idea what would motivate a release.
Needless to say, the show was hyped pretty heavily in Japan in 1967, spawning manga spin-offs, toys (from Yamato, if you’re looking), picture books, and of course the live-action movie. I’m not sure how involved Toei was in all of these, but I think it’s interesting that at least one book had a “Robot Kong” who looked completely different from what we got on screen:
For a complete episode guide, I refer you to an excellent piece by Sci-Fi Japan on the program.
