Trivia / Nadia: The Secret of Blue Water

  • Cross-Dressing Voices: Averted in the dub: the three lead roles are played by actual kid actors instead of adult females.
  • Fake Brit: In ADV's English dub, American Jennifer Stuart voices the British Electra. Sarah Richardson and Martin Blacker also voice Grandis and Sanson, respectively, with British accents.
  • Fake Nationality:
  • Pop-Star Composer: Yukihiro Takahashi, from Sadistic Mika Band and Yellow Magic Orchestra, was one of the composers for the show.
  • Recycled Soundtrack: The most epic battle scores in Nadia would be later used in the score of Evangelion 3.0; both animations were directed by Hideaki Anno and scored by Shiro Sagisu, who added a full orchestral arrangement, electric guitars and chorus lines in English to the originals. Case in point, "Almighty Battleship New Nautilus" from Nadia, to "The Anthem" from 3.0
  • Similarly Named Works: Secret of Cerulean Sand
  • Troubled Production: Aside from the unexpected decision to extend the show to 39 episodes (hence the Korean-animated filler arc), there were other problems plaguing the show's production progress. Anno reportedly disliked the original script for the show, and decided to rewrite it from scratch. Furthermore, any "suggestions" from NHK on how to "improve" the show were instantly disregarded, hence the Darker and Edgier tone for most of the canonical episodes. Because of Anno's demand for perfectionism, many episodes ran late, with Anno spending more than eighteen hours per day on the show! At one point, after episode 20 was broadcast, it took an entire month for audiences to see the subsequent one. The budget for the show also caused Gainax to lose more than ¥800 million (half a million dollars!) in finances. They were also denied any of the rights. Perhaps because of this, neither Gainax nor NHK worked together on another show, while Anno fell into the heavy bout of depression that led to Neon Genesis Evangelion.
  • What Could Have Been: Hayao Miyazaki wrote the outline that would later serve as the basis for this series. One wonders what Miyazaki's version would have been like had anything come of it while he was more directly involved.
