History Trivia / TheSecretLifeOfPets

* WhatCouldHaveBeen: A video found on the movie's Website/{{Facebook}} page showed a [[LogoJoke variant]] of the Creator/IlluminationEntertainment logo where a Minion is seen teasing a Beagle puppy with a ball, only to get caught in the act by a group of dogs and chased off-stage. Said variant did not make it into the final film and was instead replaced by [[https://www.youtube.com/watch?v=2qVtdPEPNpo this]].

** Before Lee Unkrich directed Toy Story 3, he came up with the idea for a untitled film that [[https://t.co/GMd0vG3JcI "had similar elements with The Secret Life of Pets".]]

** Also from the Japanese dub, Creator/MiyukiSawashiro's role as Gidget sounds a little bit off compared with her normal modus operandi of voicing TheCutie or the ActionGirl, as she basically sounds like [[Franchise/StreetFighter Cammy White]] after smoking a [[ContraltoOfDanger whole cigarette pack]], albeit mostly when she is screaming. Similarly, Creator/YuukiKaji (Norman), Creator/MamoruMiyano (Tiberius), and Creator/BanjoGinga (Pops) sound very different compared with their normal modus operandi here.[[note]] In Kaji's case, he speaks with the same voice he used as [[Manga/JoJosBizarreAdventure Koichi Hirose]], albeit digitally distorted to make him sound like a guinea pig, in Miyano's case, he speaks with a deeper, slurred voice, and in Ginga's case, he speaks with an unspecified [[JustAStupidAccent European accent]].[[/note]]

* ActingForTwo: Creator/SteveCoogan not only voices the hairless Sphynx cat Ozone, but also Reginald, the cat at Duke's old home.

* DuelingMovies: With ''WesternAnimation/FindingDory'', which also has animals in captivity. It's also a direct duel at the box office, coming about 4 weeks after ''Dory's'' premiere.
* FollowTheLeader: The film's success led to other studios to try to capitalize on the premise of an animated film focusing on pets, such as ''WesternAnimation/TheQueensCorgi'' and ''WesternAnimation/DCLeagueOfSuperpets''.
* InternationalCoproduction: Just like all the Illumination's films the animation was made by Illumination Mac Guff studios in France.
** This also can goes to the Latin American Spanish dub, as it was dubbed using voice actors from ''almost'' all the Latin American countries with voice acting industries in the region, (Mexico, Colombia, Argentina, Venezuela, Chile, Peru[[note]]Despite that country doesn't have a notorious voice acting industry compared with other South American countries and it's mostly reserved for local productions, this is started to change by 2017, albeit with direct-to-video films almost exclusively.[[/note]] and the United States in Los Angeles CA.[[note]]This is somewhat cheating, since Creator/EugenioDerbez did the dub voice of Snowball from there, despite being Mexican.[[/note]]) something that was never tried before in Latin America, as other dubbing coproductions normally involved two or three countries at least.

** Sort of in the Japanese dub: Snowball is voiced by Creator/RyuseiNakao, a voice actor well known for voicing villanous roles in {{Anime}}, like [[Manga/DragonBall Frieza]] or [[Manga/{{Bleach}} Mayuri Kurotsuchi]], but in foreign media, he normally tends to dub heroic roles like WesternAnimation/DarkwingDuck, [[WesternAnimation/TinyToonAdventures Buster Bunny]], [[WesternAnimation/{{Animaniacs}} Yakko Warner]], and others. Snowball is anything but ''heroic'', and one of the few times he voiced a villain in a foreign dub.

** In the Latin American dub, Creator/EugenioDerbez as Snowball is also unusual, as he is normally typecasted with heroic roles or roles related with comedy.

** In the concept arts made by Éric Guillon, there's several different designs for the characters an exemple is Max being an yellow Fox Terrier and his owner Katie having ginger hair.

* InternationalCoproduction: Not the film, but the Latin American Spanish dub, as it was dubbed using voice actors from ''almost'' all the Latin American countries with voice acting industries in the region, (Mexico, Colombia, Argentina, Venezuela, Chile, Peru[[note]]Despite that country doesn't have a notorious voice acting industry compared with other South American countries and it's mostly reserved for local productions, this is started to change by 2017, albeit with direct-to-video films almost exclusively.[[/note]] and the United States in Los Angeles CA.[[note]]This is somewhat cheating, since Creator/EugenioDerbez did the dub voice of Snowball from there, despite being Mexican.[[/note]]) something that was never tried before in Latin America, as other dubbing coproductions normally involved two or three countries at least.

* TheOtherDarrin: Due to allegations against him in late 2017, Creator/LouisCK will not be voicing Max in the sequel. [[http://collider.com/the-secret-life-of-pets-2-cast/ It was revealed that]] Creator/PattonOswalt would take over the role.

* CelebrityVoiceActor: Creator/LouisCK, Eric Stonestreet, Creator/KevinHart, JennySlate, Ellie Kemper, Lake Bell, Bobby Moynihan, Hannibal Buress, and AlbertBrooks.

** Creator/RyuseiNakao (Snowball) and Creator/KoichiYamadera (Ozone) worked together in the ''Franchise/DragonBall'' franchise as Frieza and Beerus respectively, in ''WesternAnimation/TinyToonAdventures'' as Buster Bunny and Plucky Duck respectively, and also in both ''Disney/SaludosAmigos'' and ''Disney/TheThreeCaballeros'' as Jose Carioca and WesternAnimation/DonaldDuck respectively too.

* ActorAllusion: Gidget wins Tiberius over by promising to be his best friend. Tiberius reacts with delight. In ''WesternAnimation/FindingNemo'' Marlon (voiced by Creator/AlbertBrooks who also voices Tiberius) has a line wherein he declares intent to be best friend to a little light that turns out to be the lure of a predatory Angler fish.

* CastingGag:
** In the Japanese dub, it's not the first time Creator/RyuseiNakao (Snowball) has voiced a [[WesternAnimation/TinyToonAdventures rabbit]], a [[WesternAnimation/AaahhRealMonsters rabbit-like being]] or [[Manga/DragonBall someone who wants to get rid of the human race]]. The same goes for Creator/KoichiYamadera (Ozone) as he already voiced a cat, except [[Manga/DragonBall he's also the God of Destruction]][[note]]And incidentally, just like Beerus, he's also a hairless cat.[[/note]], and Creator/YuukiKaji (Norman) already voiced another guy [[Film/{{Fury}} named Norman]], a [[LightNovel/AccelWorld fat guy, who is also a pig in the virtual world, rather than a guinea pig]], or a [[http://www.animenewsnetwork.com/interest/2017-05-02/takahiro-sakurai-promotes-apartment-complex-as-butler-chipmunk/.115554 rodent, for that matter]].
