Eight Riders vs. GingaOh

Kamen Rider: Eight Riders vs. GingaOh (仮面ライダー 8人ライダーVS銀河王) is the movie of Kamen Rider (Skyrider). It unites the first eight Kamen Riders as Skyrider joins with the Seven Legendary Riders before him.

Overview
Eight 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.

It was the first tokusatsu superhero feature screened at Toei Manga Festival since ' and ', 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.

Planning
In the original story draft by Shotaro Ishinomori, Kamen Rider was to confront Neo-Shocker's Vampire Army (吸血鬼軍団), which intended to use the gravity-controlling artillery developed by Dr. Ramon (羅門博士). Air fighting sequences were to fully demonstrate the Skyrider's flight capability. Dr. Ramon and Neo-Shocker's base at Mt. Fuji, the latter of which also appears in the finished work, were created at this stage, with Dr. Ramon envisioned as a mastermind manipulating both Kamen Rider and Neo-Shocker. Additional enemy characters were Neo-Shocker's executive, Count Dracula (ドラキュラ伯爵), accompanied by a subordinate monster, the -based Teranodojin (テラノドジン), who was represented by rough design drawn by Ishinomori.
