* ActorAllusion: Syaoran's voice actors; Creator/MiyuIrino happened to start travelling across dimensions in ''KingdomHearts'' as a young brownhaired kid. Creator/JasonLiebrecht also voiced a kindhearted hand to hand fighter from ''VideoGame/StreetFighterIV'' suffering amnesia who was related with a dude who had a huge chin.
* CreatorBacklash: CLAMP was very dissatisfied on how the anime turned out due to ExecutiveMeddling. This results to having ProductionIG adapting the Tokyo Arc instead, disregarding all the filler episodes from the anime.
* ExecutiveMeddling: NHK produced the series to be on par of their adaption of Manga/CardCaptorSakura resulting in a more lighter adaption and rejecting any more of the violent moments. Creator/BeeTrain was given [[ChristmasRushed sixth months]] to animate.
* FanNickname: Quite a few.
** The names Fai gave everyone in Outo became quite popular among the fans: "Big Doggy" for Kurogane, "Little Doggy" for Syaoran, "Big Kitty" for Fai, and "Little Kitty" for Sakura.
** Fai-mommy and Kuro-daddy are also canon nicknames that have taken on a second life in fandom.
** Ass-Chin for Fei Wong
** "Cloney" for [[spoiler:Syaoran's heartless clone, sometimes called C!Syaoran in contrast to R!Syaoran]].
** Junior [[spoiler:or Syaoran-jr when Real!Syaoran turned out not to be a real at all, but Sakura and Syaoran Li's son taking his father's name.]]
** [[spoiler: Tsubasa-kun and Tsubasa-chan]]
* HeyItsThatVoice: Creator/MaayaSakamoto, who voices Tomoyo, also voiced the Sealed Card(The Nothing/[[spoiler: The Hope]]) from Manga/CardcaptorSakura's second movie. She also sang Manga/CardcaptorSakura's third opening theme song "Platinum".
* IKnewIt - Some of the fans actually guessed the [[spoiler:MyOwnGrampa]] thing more than two months before chapter 223 was published. Wow.
** And some knew the names of the real Syaoran and Sakura a long time ago, too, although most if not all of the people who Knew It only knew one or the other
** At least one person guessed that [[spoiler:[[DeadAllAlong Yuuko was dead]]]] long before it was actually revealed.
** {{Jossed}}: A lot of fans were convinced that [[spoiler:Fai was going to die]] before the series ended. [[spoiler:He didn't.]]
* NamesToKnowInAnime: You have the manga team CLAMP of course.

* TheOtherDarrin:
** Kusanagi and Tomoyo got their dub [=VAs=] replaced in the [=OVAs=].
** [[TheBigBad Fei Wang Reed]] was first voiced by RandyTallman in the dub but had to be replaced with R. Bruce Elliot for the second season, following Tallman's [[AuthorExistenceFailure death]].
* TalkingToHimself: Tokyo!Subaru and Tokyo!Kamui are both voiced by MicahSolusod in the English dub.
* WhatCouldHaveBeen:
** CLAMP originally made the [[http://www.youtube.com/watch?v=uIO8YQnR5t8 storyboard]] for the second season opening. But it got rejected by Bee Train in place for the current second opening which is a slide show.
** The anime could have a third season. But due to NHK's ExecutiveMeddling to make a show lighter and kid-friendlier as opposed to being close to the manga which is heading toward DarkerAndEdgier, CLAMP became disappointed with the results and have ProductionIG continue the anime in a form of the [=OVAs=].
