As it aired right after the show “Ultraseven” ended, no Ultra heroes and no monsters appear in “Kaiki Daisakusen” in which the SRI members who courageously stand up against “science crimes” are depicted incorporating minor tokusatsu scenes instead of covering ostentatious tokusatsu scenes featuring Ultra heroes, monsters and futuristic equipment.
While it is explained “Kaiki Daisakusen” is a TV show produced in the same line with the Toho “Transformative Human Series” movies consisting of “The H-Man” (1958); “The Telegian” (1960); “The Human Vapor” (1960).
I found the no-hero-and-no-monsters show very much unsatisfactory when watching “Kaiki Daisakusen” as a kid, I now realize it is another form of TV tokusatsu shows that is fully enjoyable.
Meanwhile, it is another fun thing to see Akiji Kobayashi (1930-1996) who acted Captain Muramatsu in “Ultraman” appear in “Kaiki Daisakusen” almost regularly as a police sergeant who cooperates with the SRI team although the sergeant Taizo Machida is much more human than Cap. Muramatsu as Machida often makes mistakes.
Furthermore, while the SRI chief Tadashi Matoya was played by Yasumi Hara (1915-1997), it is hilarious to see him appear as the owner of the hume pipe storage in Ultraman Episode 15 (he appeared in the episode before acting the SRI chief).
It is said that Hara was known to be a good-looking actor who appeared in popular TV series including a daytime soap opera and fascinated Japanese housewives even before his appearance in “Ultraman.”
I greatly admire Jissoji’s playful mind to apply such a popular actor to the man who yells at children in a funny way and gets into a lot of trouble, and Hara himself seems to have played the man happily at Jissoji’s request as Hara was also one of Jissoji’s favorite actors.
