*** Creator/YoshitsuguMatsuoka, the guy who has become known for his voice acting as harem protagonists like [[LightNovel/SwordArtOnline Kirito]] or [[LightNovel/IsItWrongToTryToPickUpGirlsInADungeon Bell Cranell]], was chosen to voice Betelgeuse Romanee-Conti. To say this fits is a [[AxeCrazy massive]], ''[[BigBad massive]]'', '''[[EvilIsHammy massive]]''' understatement that needs to be seen to be believed.
*** Creator/YukaIguchi is well-known for voicing young or teenage girls with high-pitched voices like [[LightNovel/ACertainMagicalIndex Index]] or [[LightNovel/{{Bakemonogatari}} Tsukihi]]. In this anime, she however voices Crusch, who is not only an adult but also possesses a very deep voice compared with the characters that Iguchi normally voices.

* RelationshipVoiceActor:
** In the Japanese version:
*** In [[LightNovel/IsItWrongToTryToPickUpGirlsInADungeon another universe]], [[Creator/YoshitsuguMatsuoka Betelgeuse]] was the harem protagonist with [[Creator/InoriMinase Rem]] being his female lead. Though, [[Creator/YokoHikasa one of Betelgeuse's fingers]] is still a villain.
*** From ''LightNovel/SwordArtOnline'':
*** The last time [[Creator/YoshitsuguMatsuoka Betelgeuse]] and [[Creator/TakehitoKoyasu Roswaal]] were at war with each other, they were on opposite sides of the moral spectrum with Beteleguese being TheHero rescuing [[Creator/HarukaTomatsu Fortuna]] from Roswaal who was the BigBad of the [[Recap/SwordArtOnlineFairyDanceArc Fairy Dance arc]].
*** Probably unintentional, but [[Creator/MaayaSakamoto the holders of]] [[Creator/AkiraIshida the Authority of Greed]] are the {{Big Bad}}s of the [[Recap/SwordArtOnlineAlicizationArc Alicization Arc]] (Sakamoto in the first half and Ishida in the second half).
*** [[Creator/RieTakahashi Emilia]] and Petra (Marika Kouno) are part of the voice actor idol unit [[Manga/SeiyusLife Earphones]].

*** [[Creator/YoshitsuguMatsuoka Betelguese]], [[Creator/YuusukeKobayashi Subaru]], [[Creator/MinamiTakahashi Theresia van Astrea]], [[Creator/TakehitoKoyasu Roswaal]], [[Creator/YuichiNakamura Reinhard]], [[Creator/ChinatsuAkasaki Felt]], [[Creator/NobuhikoOkamoto Garfiel]], [[Creator/MaayaSakamoto Echidna]], [[Creator/RieKugimiya Pandora]], [[Creator/AkiraIshida Regulus]] and [[Creator/YokoHikasa Betelguese's Finger]] are [[Manga/FoodWars Soma Yukihira, Zenji Marui, Megumi Tadokoro, Gin Dojima, Kojiro Shinomiya, Alice Nakiri, Ryou Kurokiba, Mana Nakiri, Momo Akanegakubo, Eishi Tsukasa, and Natsume and Orie Sendawara]].
** In the English dub:
*** From ''Manga/MyHeroAcademia'':
*** [[Creator/PatrickSeitz Kadomon]] is currently the #1 hero after All Might's retirement, [[Creator/ZenoRobinson Garfiel]] takes his place, and [[Creator/AnairisQuinones Echidna]] is the #5 hero.

** A cross-language version happens between the Japanese and Latin American Spanish dubs: Miklotov [=Mc=]Mahon's voice actors in those versions, Creator/MotomuKiyokawa and Creator/JesseConde respectively, both voiced [[Anime/NeonGenesisEvangelion Kozo Fuyutsuki]] in their respective versions.

* NamesTheSame:
** Puck with the [[Manga/{{Berserk}} other Puck]].
** Along with Felix and WesternAnimation/{{Felix|TheCat}}. Bonus points in that they're both cats (even if the former is only [[LittleBitBeastly slightly]] so).
** Rem is not to be confused with [[LightNovel/HowNotToSummonADemonLord another isekai girl]] named Rem. Or the [[Manga/DeathNote shinigami]].
** Garfeil's beast form makes sense when you consider the other ComicStrip/{{Garfield}}.

* SleeperHit: While the anime did gain a lot of attention before airing in Japan, not many people were expecting much out of it in other countries the original light novels didn't have any official translations at the time, as well as the fact that the manga adaptation covered less than three episodes' worth of material before the first episode was aired. The initial reviews were mixed with critics saying the first episode was SoOkayItsAverage for a seemingly overdone plot, but stellar production values. However, the continual rise in quality, as well as an extremely impressive WhamEpisode of Episode 7, made ''Re:Zero'' become one of the highest-rated anime of Spring 2016, beating out highly anticipated shows from the first season like ''Manga/MyHeroAcademia'' and ''Anime/KabaneriOfTheIronFortress''. The popularity and praise that this show would receive would only skyrocket as it continued its run. Episode 15, in particular, is considered to be one of [[WhamEpisode the most shocking episodes]] of any show in years, to the point of many comparisons with ''[[Anime/NeonGenesisEvangelion End Of Evangelion]]'', ''Franchise/MadokaMagica'' Episode 3, or the Eclipse from ''Manga/{{Berserk}}'' have been made, only increasing the love and interest for the show even more.

* FanNickname: In some circles, Subaru's name is often replaced with other recognizable Japanese automotive names, most commonly "Toyota".
** "[[CosmicPlaything Suffaru]]" also became a popular nickname for Subaru thanks to his status as TheWoobie in the show.
** From her detractors, Emilia has gotten the nicknames "Mobmilia" and "Gomilia" (calling her an NPC and "Trashmilia" respectively) in the Japanese fandom. Likewise, but to a lesser extent, Rem gets the forum nickname "Gori-rin" in Japan.
** Betelgeuse is also commonly called Beetlejuice in reference to the titular movie character also named Betelgeuse but pronounced Beetlejuice.
** Tappei Nagatsuki, the original author, has been nicknamed the "Japanese Creator/GeorgeRRMartin", above the likes of Creator/HideakiAnno, Creator/MohiroKitoh, and even the '''[[Creator/GenUrobuchi Urobutcher]]''' himself. Make of that what you will.

** Julius was Creator/ChrisNiosi in Season 1, but afterward was taken over by Creator/AlejandroSaab, possibly due to the controversy surrounding Niosi that arose between seasons. Niosi [[https://twitter.com/Kirbopher/status/1326634717383307264 gave his best regards]] to Saab for it.

** The second season was originally scheduled to air in Spring 2020 continuously with no breaks, with its first episode premiering on April 1 and its final episode ending on September 23 (which are [[SignificantReleaseDate Subaru and Emilia's birthdays, respectively]]) but the broadcast delay threw this out the window.

* ScrewedByTheNetwork: The Western distribution of ''Re:Zero's'' anime turned into a disaster after its initial broadcast airing was completed. The physical disc release of the series was poorly marketed by Creator/{{Funimation}} and more importantly, had [[https://www.funimation.com/forum/topic/16698/re-zero-supposed-poor-video-quality-on-bluray/21 serious visual quality problems with the footage]] to the point that Funimation went so far as to offer a trade-in for dissatisfied customers (the first time in the company's history it had done so). On top of that, the dissolution of the then-partnership between Funimation and Crunchyroll meant the show was unavailable on legal streaming services for quite some time. The damage this caused to the viewing statistics was so severe that Subaru's English voice actor revealed in [[https://www.reddit.com/r/anime/comments/grs66b/ama_professional_voice_actors_sean_chiplock_and/fs1771l/ a Reddit AMA thread in May 2020]] that he believes it is entirely possible the second season will not get dubbed (adding on to the fact that at the time of this thread, the [=OVAs=] had been announced for a dub but he had not been contacted to reprise his role). These fears turned out to be unfounded after Crunchyroll launched a dub of the second season in August 2020 with all the main cast reprising their roles.

* Echidna is this to Creator/AnairisQuinones. While [[Manga/MyHeroAcademia Mriko]] gained a lot of attention, her performance as Echidna has cemented her career as a voice actress.

*** [[Creator/PatrickSeitz Kadomon]] is currently the #1 hero after All Might's retirement, [[Creator/ZenoRobinson Garfiel]] takes his place, and Echidna (Anaris Quinones) is the #5 hero.

** Rem is not to be confused with [[LightNovel/HowNotToSummonADemonLord another isekai girl]] named Rem.
