* ActorAllusion:
** Creator/LucyLiu's previous role before Viper? [[Film/KillBill O-Ren Ishii,]] also known by the name of "Cottonmouth".
** Monkey's VA is Jackie Chan. His son played Monkey's voice in ''Secrets of the Furious Five,'' and Monkey's VA for the TV series is the same man who played Jackie Chan himself in ''JackieChanAdventures''!
** At one point, Master Croc does [[Creator/JeanClaudeVanDamme a full split]].
** Many of Black's phrases get snuck into the film, such as "Skadoosh!" That one in particular was [[spoiler:the PreMortemOneLiner against Tai Lung.]]
* AllStarCast[=/=]CelebrityVoiceActor: Creator/JackBlack, Creator/LucyLiu, Creator/AngelinaJolie, Creator/JackieChan, Creator/DustinHoffman, Creator/SethRogen, Creator/DavidCross and Creator/MichaelClarkeDuncan are either primary focus characters or have significant roles in the film.
* DoingItForTheArt: The first reaction of the producers at hearing from the animators that they didn't know how to do the rope bridge fight was encouragement; that meant that ''nobody'' had done it before and from that challenge, one of animation's wildest action sequences was created.
* GrowingTheBeard: Served as this for the DreamworksAnimation Studio. Following it's release and success, Dreamworks backed away from trying to duplicating the Shrek formula. Even the Shrek's next [[ShrekForeverAfter sequel]] and [[WesternAnimation/PussInBoots spinoff]] took more of a page from Kung Fu Panda's book.
* HeyItsThatVoice: In the holiday special, [[Series/ThirtyRock Kenneth]] is Wo Hop.
** Aside from the main cast, Wayne Knight (Newman, ''Series/{{Seinfeld}}'') is the voice of the main gang boss in Po's dream.
** Also, James Hong ([[Film/BigTroubleInLittleChina Lo Pan]], [[WesternAnimation/JackieChanAdventures Daolon Wong]], [[Disney/{{Mulan}} The emperor's counsel, Chi-Fu]]) is the voice of Mr. Ping.
*** He was also Dan Fogler's mentor in ''Film/BallsOfFury''. Fogler voices the goose who delivers the message to double the security surrounding Tai Lung.
*** He also played a lot of bit parts in ''Series/HawaiiFiveO''.
** Creator/MichaelClarkeDuncan as Captain Vachir.
** Creator/JackieChan a.k.a. [[RushHour Inspector Lee]] as Master Monkey.
** Creator/AngelinaJolie is Tigress, Creator/LucyLiu is Viper, Creator/SethRogen is Mantis, Creator/DavidCross is Crane, and Creator/DustinHoffman is Master Shifu.
** This isn't the first time Creator/JackBlack and Creator/AngelinaJolie have [[WesternAnimation/SharkTale starred in an animated feature together]], however, their characters have no interaction with each other in that one.
** The [[Film/TheMatrix Keymaker]] is Master Oogway.
** The Japanese dubbed version, interestingly, has many voice actors from many anime series and videogames that deals with fighting:
*** Master Monkey [[HiroyaIshimaru is]] [[MazingerZ Koji Kabuto]] and Creator/JackieChan.
*** Master Mantis [[TakuyaKirimoto is]] [[Manga/{{Naruto}} Yoroi]] and [[Manga/FistOfTheNorthStar Shin]]
*** Master Crane [[Creator/MitsuakiMadono is]] [[{{X1999}} TV!Sorata Arisugawa]] and [[WesternAnimation/TheFairlyOddparents Cosmo]]
*** Master Oogway [[KoseiTomita is]] [[MazingerZ Dr. Hell]]
*** Captain Vachir [[Creator/DaisukeGori was]] [[VideoGame/{{Tekken}} Heihachi Mishima]]
*** Zeng [[Creator/WataruTakagi is]] [[GreatTeacherOnizuka Eikichi Onizuka]]. And to be faithful to Dreamworks, [[WesternAnimation/ThePenguinsOfMadagascar Dr Blowhole]].
*** Master Tigress is voiced in Japanese by YoshinoKimura, who maybe many Western viewers can recognize her as the Japanese wife from the movie ''Film/{{Blindness}}''
*** Lord Shen [[Creator/KeijiFujiwara is]] Film/IronMan and [[CrayonShinChan Hiroshi Nohara]]
*** Wolf Boss [[Creator/ToshiyukiMorikawa is]] TekkamanBlade and [[Anime/DevilMayCryTheAnimatedSeries Dante]]
*** And The Narrator in the Japanese trailers is the [[Creator/AkiraKamiya grand-daddy of all fighting anime characters]], [[Manga/FistOfTheNorthStar Kenshiro]].
** ''WesternAnimation/KungFuPanda2'' brings us:
*** Lord Shen or [[Creator/GaryOldman Commissioner Jim Gordon?]] Perhaps [[Film/TheDarkKnightSaga Batman]] isn't the only one with a secret identity. He's also [[Film/HarryPotter Sirius Black]], which makes the line about [[spoiler:scars healing]] unintentionally hilarious.
*** Master Croc is that Belgian beefcake we all know and love, Creator/JeanClaudeVanDamme.
*** Master Thundering Rhino is [[WesternAnimation/GreenLanternFirstFlight Sinestro]].
*** [[spoiler: Po's father]] is [[{{WesternAnimation/Nine}} 8]].
** WesternAnimation/KungFuPandaLegendsOfAwesomeness:
*** Wallace Shawn as Taotie.
*** [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Hoss Delgado]] voices Hundun.
*** [[HotInCleveland Victoria Chase]] is Fenghuang.
*** Creator/MalcolmMcDowell as Shirong, Shifu's father.
** In the French dub of WesternAnimation/KungFuPanda2, the Wolf Boss is [[Franchise/MassEffect Garrus]]. Monkey is [[WesternAnimation/SouthPark Kyle and Kenny]]; Lord Shen is [[TheNanny Niles]], which surprisingly works [[LargeHam perfectly]]! Rhino is [[WesternAnimation/TheSimpsons Homer Simpson]]; Crocodile is [[WesternAnimation/SonicSatAM Robotnik]]; Ox is [[WesternAnimation/TheLegendOfKorra Amon]].
** Meanwhile, in Hong Kong, Master Monkey is still Creator/JackieChan. While his son is Crane.
* LifeImitatesArt: Creator/DustinHoffman (Shifu) tutored Creator/JackBlack (Po) on acting during production.
* TheOtherDarrin / ThePoorMansSubstitute: In the TV series the voices of Po, Master Shifu and the Furious Five are replaced by their video game counterparts.
* PlayingAgainstType: [[Film/CharliesAngels Lucy]] [[Film/KillBill Liu]] as sweet-natured, kindly Viper.
* WhatCouldHaveBeen: In an early version of the original movie's script, Po was intended to be something of a ParodySue, expecting the Furious Five to love him and adore him as much as he liked them. Apparently, Jack Black intervened because he realized how unlikeable this made the character, and urged the writers to change Po to being insecure and well aware of his own flaws.
** The creators were going to make Mantis TheMole until character designer Nico Marlet gave him more of a playful look that played with the stereotype of a creepy praying mantis.
*** For the second movie, there was time in the plot where a female mantis was going to eat him.
** One of Viper's weapons was supposed to be a ParasolOfPain.
** Before ''WesternAnimation/KungFuPanda2'' was released, there was [[AllThereInTheManual information]] that pointed out a different backstory for Lord Shen then from what was shown: Shen's parents were said to be ashamed of his albino coloring and poor health, so they left him in the care of their advisor, the Soothsayer, who raised him like her own. Traces of this can be seen as Shen is never outright cruel to the Soothsayer, such as how he releases her before the launch of his armada, meaning that he still respects her for showing him love. This is the backstory used in the novelization.
** The Wolf Boss was originally going to be a crow, but the creators thought that would make him too similar to Shen.
** [[http://www.nick.com/pictures/kung-fu-panda-legends-of-awesomeness/kung-fu-panda-enemy-art-flipbook.html This gallery of early concept art]] reveals that [[KungFuPandaLegendsOfAwesomeness Fung's]] name in the initial planning stages was "Dirk."
** The Wu Sisters were originally going to be minions of Tai Lung in the first movie, but were taken out to make Tai Lung seem like more of a badass. Their original designs also differ greatly from their current ones, including them looking completely identical and having a rather obnoxious VerbalTic. [[http://www.youtube.com/watch?v=hDMgmSsIMew&feature=related See]] for yourself.
** Mr. Ping was going to be Po's stern boss before one of storyboard artists thought it would be funnier if he was Po's doting father instead.
