(about Alien Shadow) “Female molds of sculptures have a strange feeling of vitality. I wanted to make the female mold into the face so that the inverted bumps and dents could be applied to the face. Although I don’t think it looked so good in the show, I’d like to complete Alien Shadow by sculpting it myself as a future challenge.
“By the by, my sculpture work “Fossil of Human with Wings” I exhibited to Shin Seisaku Kyōkai (Association for New Art) shortly after I resigned Tsuburaya Productions was worked out by making this whole body into the female mold.”
(about Gublla) “I got the idea from the caterpiller.”
Although it is a bit hard to understand Narita’s words about his sculpture work, I think it means he applied the idea of inverted bumps and dents to his work from Alien Shadow by making the whole human body into the dented form.
As to the heads sculpted by Ryosaku Takayama for the show, the photo below tells us that the helmets were removable. It is said the aliens’ clothes were made by the dress-making section of Tsuburaya Productions.
As to Gublla, Tetsuo Yamamura says that the costume was really well made while the head and the tips of the arms were made of FRP with its body including the tail cast from the mold as each segment was different in size and shape.
It is said that Gublla’s hair was made from plant fibers, the same material as Woo.
Yamamura says the scene of Gublla’s head being melted down was filmed with a plaster head coated with gold wax as they were melting the wax with a hairdryer.
