This was the last Toho tokusatsu film to be shot in the 2.35:1 (CinemaScope) aspect ratio before Godzilla 2000 - Millennium (1999). This was also the final Toho tokusatsu film to be shot in anamorphic widescreen. (All subsequent Toho tokusatsu movies shot on film were in spherical lens, with either a hard-matte or digital cropping, which causes much film grain when cropped into their intended aspect ratio.)
The film takes place in 1988.
