Tohl Narita: (about Alien Poll) “I like to design what doesn’t require an actor in it as it expands the possibilities of design.” (about Gander) “I made the wings neither the ones of feathers like animals nor mechanical ones. While I often sculpt birds for my works, I applied the sculpting method to it.”
I like this episode very much among the ones of Ultraseven as it features many attractive things such as the elaborate tokusatsu scene with the use of the miniature Pointer traveling above the snow field in the snow storm, the TDF base frozen by Alien Poll, and the drama that unfolded at stalemate featuring the TDF members and Chief Yamaoka.
It was also a noteworthy episode as it was revealed Ultraseven was vulnerable to cold and that he would have to absorb solar energy to restore his strength by flying close to the sun.
It is said that three puppets of Alien Poll (about 75 centimeters) were made by Ryosaku Takayama using latex. While not much is known about it, it seems that Takayama had been involved in sculpting puppets for puppet shows before he gained fame as a kaiju sculptor, so he must have known his stuff in sculpting such puppets as Alien Poll.
