* ActingForTwo: Creator/ChiyokoKawashima voiced both Kei Yuki and Mayu.
** Similarly in the [[Creator/VIZMedia VIZ]]/[[Creator/TheOceanGroup Ocean]] dub of ''Adieu Galaxy Express 999'', Jane Perry voiced both Kei and Mime.
* CreatorBacklash: Matsumoto has all but disowned ''Endless Odyssey''. The first episode begins with a title card in Japanese (with no English subs, strangely) proclaiming the OVA series as being merely "director Rintaro's Captain Harlock". The fallout happened when Matsumoto took offense to a weapon Rintaro planned for the demonic villains to use that (originally) generated Star of David-shaped InstantRunes.
** Matsumoto also disliked the character [[HeartwarmingOrphan Mayu]] (Tochiro's daughter) that Rintaro created for ''Space Pirate Captain Harlock''.
* ExecutiveMeddling: A lesson to animators: NEVER use religious images carelessly in works based on Creator/LeijiMatsumoto's characters, or your series ''will'' be released DirectToVideo.
* MarketBasedTitle: When the manga/anime was imported in France in TheEighties, the protagonist was renamed into "Albator". Translators thought that Captain Harlock was too close from Captain Haddock from ''ComicBook/{{Tintin}}'' and that young people would be confused by the two characters. The name has stuck since for more recent entries, although more and more exposure to the original name via the Internet and subbed home videos since the TurnOfTheMillennium has resulted in some dedicated French fandoms calling him solely "Harlock".
* TheOtherDarrin: There appear to be two ships named Arcadia. One blue (seen in the 1978 series), and the other green, seen in all other subsequent series. Until the 2014 ''Dimensional Voyage'' manga, none of the stories or animation supported the common {{fanon}} supposition that that the Arcadia was at any point destroyed and rebuilt. Or that the second Arcadia is just a newer, upgraded version of the first. [[note]]''Dimensional Voyage'' actually uses both explanations: The series has the Blue Arcadia as the successor to an older Green Arcadia used by the current Harlock's ancestors, and also as a prototype for an updated Green Arcadia Tochiro was working on.[[/note]] Their existence actually nothing more than [[ExecutiveMeddling marketing]].
** cornponeflicks.org explains it this way:
---> Takara owned the rights to model kits from Space Pirate, and Bandai owned the model rights to Galaxy Express 999. When the Arcadia was slated to appear in the first 999 film while Space Pirate was still on the air, it would've amounted to free advertising for Takara; therefore Bandai had Studio Nue design an alternate version for them, to avoid giving their primary competition any leg up. (Studio Nue had also designed the blue Arcadia, and would shortly gain fame for its Macross design work.) In its own way, it's not far removed from having two different actors portray the same character in two different TV seasons or movies, in which cases viewers rarely have to contrive wild notions of secret plastic surgery in order to deal with it.
* In episodes 9 & 10 of the original series, Harlock was understudied by the late Kan Tokumaru, the reason being the Creator/MakioInoue discovered that he had polyps in his throat and wanted to get them treated immediately, and he asked TOEI to let him take a break for two weeks to recover from the treatment, and apparently many fan letters were received in regards to this.
* OvertookTheManga
* {{Surprisingly Lenient Censor}}: Carl Macek didn't censor any of the nudity or the live childbirth out of the English dub; he was amazed nobody told him to change it.
* {{Typecasting}}: This is the [[Anime/VoltesV second]] time Creator/NorikoOhara voiced an elegant, beautiful alien woman. After ''Harlock'', she would go on to voice [[AlienPrincess Princess]] [[YukiOnna Oyuki]] from ''Manga/UruseiYatsura''.
* WhatCouldHaveBeen: During a speech at an anime expo in 1995, director Noboru Ishiguro revealed that he was supposed to have made his debut in ''Anime/SpaceBattleshipYamato'' as the alter-ego of the brother of the main character. However, budget constraints forced the team to cut that part out alongside the 13 episodes where he would have appeared.
* WriteWhoYouKnow: Maji is Creator/LeijiMatsumoto and Yattaran is his assistant and ''Manga/{{Area 88}}'' creator Kaoru Shintani. Matsumoto's cat Mii also appears.
