Kamen Rider The Movie: 8 Riders VS GingaOhEight Riders vs. GingaOh is the first original theatrical production in six years, following the 1974 film Five Riders vs. King Dark, which accompanied the TV series Kamen Rider X. In the interim, theatrical releases of Kamen Rider Amazon and Kamen Rider Stronger had been screened as part of the Toei Manga Festival in spring and summer of 1975, having been respectfully “blown-up” from Amazon’s sixteenth episode and Stronger’s seventh episode. A the first time for the Kamen Rider Series, this film was produced with a running time of 40 minutes, ranked as a “class A” production: The cost of production was twice the average Toei Manga Festival production. Initially, it was considered to release the film in its own right beyond the children’s box office.
Kamen Rider The Movie: 8 Riders VS GingaOhIt was the first tokusatsu superhero feature screened at Toei Manga Festival since Spider-Man and Message From Space: Galactic Wars, both screened in 1978. This release would begin a revival of tokusatsu features incorporated into the festival. Led by Skyrider, this film featured the debut of the hero’s new “Powered Skyrider” form, prior to its debut in the twenty-eighth episode of the Kamen Rider TV series. While an action-oriented work with less drama, the film was managed by creator Shotaro Ishinomori, who oversaw large-scale action and special effects scenes.
