how did they enlist Teruyoshi Nakano?
I don't get it - I always thought that North Korea and Japan were bitter enemies of each other, especially around the time this film was made. So what was Teruyoshi Nakano, THE premier special effects director of Toho studios from the late 60's to early 80's, doing working on this film? What was his function exactly? I'd assume he helped with the pyrotechnics as it resembles his work.
The suit design and composite shots are much worse than anything he was doing at the same period (look at Godzilla 1985).
I see that his career ended shortly afterward... did working on this film blacklist him in some way?
