It was not until 2002 that the "Hades arc", the finale to Kurumada's manga, was adapted into an original video animation (OVA) series.
There have also been a number of theatrical releases, which do not belong to the regular chronology of the series, as they contradict its storyline on several occasions.
The films are titled Evil Goddess Eris (1987), The Heated Battle of the Gods (1988), The Legend of the Crimson Youth (1988), Warriors of the Last Holy War (1989) and Heaven Chapter Overture (2004).
The latest was a 3D CG animation released on June 21, 2014, titled Saint Seiya: Legend of Sanctuary.
One, an edited dub produced in Toronto, Canada, by DIC, was renamed Knights of the Zodiac, and was broadcast on Cartoon Network in 2003.
The other dub, produced by ADV Films in Houston, Texas, was fully uncut and lasted for 60 episodes.
It was released to bilingual DVD from ADV Films, but production ceased when Knights of the Zodiac was canceled on Cartoon Network.
The first thirteen episodes of the OVA series corresponding to the "Hades saga" of the manga were broadcast on Animax (a Japanese pay-per-view channel) from November 2002 to April 2003, and then released on DVD during the year 2003.
These thirteen episodes, named Hades: Chapter Sanctuary (冥王ハーデス十二宮編, Meiō Hādesu Jyūnikyū Hen), were directed by Shigeyasu Yamauchi, still with character designs by Shingo Araki and Michi Himeno, while the scripts were adapted from the manga by Michiko Yokote.
On July 4, 2006, the newly published fifteenth volume of the Saint Seiya Japan Complete Version manga brought the news that production of Hades: Chapter Inferno Part 2 (冥王ハーデス冥界編 後章, Meiō Hādesu Meikai Hen Kōshō) had begun.
