Nadia: The Secret of Blue Water

Nadia: The Secret of Blue Water (ふしぎの海のナディア Fushigi no Umi no Nadia, lit. "Nadia of the Mysterious Seas") is a Japanese anime television series that originally aired from April 13, 1990, to April 12, 1991, on NHK-G in Japan.

The series was inspired by the works of Jules Verne, particularly Twenty Thousand Leagues Under the Sea and the exploits of Captain Nemo. The series was created by NHK, Toho and Korad, from a concept of Hayao Miyazaki, and directed by Hideaki Anno of Gainax.

Dubbing History
The series was originally licensed by Streamline Pictures in 1991. An English dub of the first eight episodes was directed by Carl Macek and released on separate VHS tapes between March 1992 and August 1993 under the title of Nadia. Macek pitched the episodes for a television broadcast, intending to use the funding to dub the rest of the series, but was turned down. The episodes would later be re-released by Orion Home Video on two VHS compilation tapes in January 1996 as The Secret of Blue Water. Compilations for the rest of the series were planned by Streamline, but Orion declined to have them produced.

In June 1999, ADV Films announced they had licensed the series for North America. A new dub was be produced by ADV using their Austin-based Monster Island Studio and directed by Charles Campbell. It was released on VHS and DVD from June 19, 2001 to July 16, 2002.

With the collapse of ADV in 2009, the rights to Nadia would later be purchased by Sentai Filmworks in 2014, releasing the show with the ADV dub to Blu-Ray and DVD. In April 2022, GKIDS picked up the rights to Nadia and released it in a 4K restoration on Blu-Ray on August 2, 2022, with the ADV dub.
