** The Japanese dub is not a slouch on this either, as many of the voice actors who worked in the dub are also good singers in their own right: So far we have Creator/MaayaSakamoto (Rosita)[[note]]Who not only dubs her, she also [[http://www.animenewsnetwork.com/interest/2017-03-14/hear-escaflowne-maaya-sakamoto-sing-katy-perry-in-english/.113394 sings her songs in English]][[/note]], Creator/MamoruMiyano (Eddie and Ray), Creator/KoichiYamadera (Mike), Creator/MayumiTanaka (Miss Crawly), Creator/KisshoTaniyama (Lance)[[note]]Who is also one of the members of the duo GRANRODEO[[/note]], Creator/NanaMizuki (Becky), Creator/TetsuyaKakihara, Creator/AyumuMurase and Creator/SubaruKimura[[note]]Who is a professional rap singer[[/note]] as the members of the Frog Trio, Creator/AyaneSakura as one of the members of the Rabbit Trio, Creator/UnshoIshizuka as Marcus, Creator/KentaMiyake as the Bear leader, and Creator/{{Kujira}} as Meena's mother. Even minor, unnamed roles are voiced by big names like Creator/AoiYuuki, Creator/TesshoGenda, Creator/TaitenKusunoki and many others.

** In the Mexican Spanish dub, Rosita and Ash are voiced by Hanna Nicole Perez Mosa and Ashley Grace Pérez Mosa respectively from the Mexican pop band ''Ha*Ash'' and Buster Moon by also singer Benny Ibarra.

* TheCameo: Directors Creator/EdgarWright as a goat who auditions, and Creator/WesAnderson as Daniel, a giraffe who also auditions.

* CastingGag: A pretty hilarious one in the Mexican Spanish dub: Gunter, a pig, is voiced by a voice actor named Ruben '''Cerda''', whose surname can be translated as "sow". Taking into he is a literal pig and his mannerisms, this is quite fitting.

* CrossdressingVoices: Ms. Crawley is voiced by Creator/GarthJennings, a male actor and the film's director. The same goes in both Mexican and European Spanish dubs, but oddly averted in the Japanese one, when Creator/MayumiTanaka voices her.[[note]]Which is particularly ''ironic'' since she is very well known for voicing boys or male teens, like [[Manga/DragonBall Krillin]] and [[Manga/OnePiece Monkey D. Luffy]].[[/note]]

* RealLifeRelative: Rosita’s piglets are voiced by (and some named for) Garth Jennings’s children: Oscar, Asa, Leo, and Caspar.
* RelationshipVoiceActor: ''Lots'' of them in the Japanese dub, due of the AllStarCast that dub have:
** Creator/MamoruMiyano and Creator/KoichiYamadera [[WesternAnimation/DespicableMe2 reunites]] [[WesternAnimation/{{Minions}} again]] [[WesternAnimation/TheSecretLifeOfPets in yet another dub]] of a Creator/IlluminationEntertainment film as Eddie and Mike respectively.
** Also from the Japanese dub, Creator/MaayaSakamoto (Rosita) and Creator/NanaMizuki (Becky) previously worked together in ''Manga/BlackButler'' as Ciel Phantomhive and Alois Trancy respectively, and also in the Japanese dub of a TV series that also [[Series/{{Glee}} involves music as well]].

* CastingGag: A pretty hilarious one in the Mexican Spanish dub: Gunter, a pig, is voiced by a voice actor named Ruben '''Cerda''', whose surname can be translated as "female pig". Taking into he is a literal pig and his mannerisms, this is quite fitting.

* CrossdressingVoices: Ms. Crawley is voiced by Garth Jennings, a male actor and the film's director. The same goes in both Mexican and European Spanish dubs, but oddly averted in the Japanese one, when Creator/MayumiTanaka voices her.[[note]]Which is particularly ''ironic'' since she is very well known for voicing boys or male teens, like [[Manga/DragonBall Krillin]] and [[Manga/OnePiece Monkey D. Luffy]].[[/note]]

* ActorAllusion:
** The movie is about a singing competition. Meena is voiced by Tori Kelly, and the young Nana Noodleman, as seen in Buster's flashback at the start, is voiced by Music/JenniferHudson, both of whom also has a certain history with [[Series/AmericanIdol singing competitions]].
** This isn’t the first time Taron Egerton has played a character who forcibly broke his way out of a [[spoiler: [[Film/KingsmanTheSecretService flooded room]]]]
** It's mentioned in [[AMinorKidroduction the prologue]] that Buster initially wanted to become the first koala in space. Maybe in this life, he didn't become an astronaut. But in [[Film/{{Interstellar}} a previous life]], he went above and beyond.
** Johnny's shirt also has a prominent lighting bolt on it, possibly as an allusion to his voice actor whose first name 'Taron' is a misspelling of 'Taran'--which is Welsh for 'thunder'.
** Possibly a coincidence, but Lance’s [[spoiler: new girlfriend]] is named Becky. Lance himself is voiced by Beck Bennet.
** Gunter's voice is the same voice Nick Kroll used for The European on the ''Series/KrollShow''.
** At one point during Gunter's performance of "Shake It Off" with Rosita, Gunter dances similarly to how [[WesternAnimation/SausageParty Douche]], another character Nick Kroll played, dances in the scene where he's introduced, and both characters did this dance while in a box.
** Mike exclusively sings classic pop songs, reflecting Creator/SethMacFarlane's love of Rat Pack-era music. The same goes in the Japanese dub with the same character, except [[Creator/KoichiYamadera his voice actor]] [[Anime/JapanAnimatorExpo previously sang Enka, the Japanese equivalent]]. Mike's [[{{Jerkass}} brash attitude]] also plays up [=MacFarlane=]'s politically incorrect public image.
** Also from the Japanese dub, Creator/MaayaSakamoto's role as Rosita could be a subtle reference as her role as [[Anime/RebuildOfEvangelion Mari Illustrious Makinami]], whose plug suit is ''pink'', just like Rosita's skin. Also from this dub, Creator/AyaneSakura's role as one of the members of the Rabbit Trio could be a reference to her role as [[VideoGame/KantaiCollection Shimakaze]], whose hairclip resemble rabbit ears. And Masami Nagasawa's role as Ash could be a reference to her role as Yuri Aikawa in the ''Manga/DetroitMetalCity'' animated adaptation, albeit in a ''very'' ironic and hilarious way.
