This was the last Toho tokusatsu film to be shot in the 2.35:1 (CinemaScope) aspect ratio before Godzilla 2000 (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.
