History Trivia / JusticeLeague

** GreyDeLisle voiced both halves of the CaptainErsatz of the WonderTwins, including the male Downpour.

** And how can we forget that Superman (George Newbern) is [[VideoGame/FinalFantasyVII Sephi]][[KingdomHearts roth]]?
** A bit of an homage too, but Mark Hamill reprised his role as The Trickster from the short-lived live action ''Series/TheFlash'' TV series.

** And HOW, oh, HOW did everyone forget Michael Rosenbaum, who voices the Flash AND plays [[{{Smallville}} Lex]] [[LexLuthor Luthor]]?

** JenniferHale voiced Black Siren, Giganta, Killer Frost, Zatanna, and Inza. Her ''VideoGame/KnightsOfTheOldRepublic'' and ''VideoGame/MassEffect'' co-star, Raphael "Carth Onasi" Sbarge, voiced Deadman.
** [[{{Frasier}} Peri Gilpin]] as Volcana.

** And, of course, KevinConroy as Batman and MarkHamill as TheJoker.

** [[TheIncredibles Mirage]] is Paran Dul.

** "In Blackest Night" is about GL on trial for the destruction of a planet in a nod to ''Cosmic Odyssey''. It has nothing to do with [[BlackestNight zombie Lanterns.]]

** Famously averted with Batman. [[http://www.youtube.com/watch?v=uoRundeX6O0 Yes, really]]. This is something the producers have been ''dying'' to work into the show ever since ''WesternAnimation/BatmanTheAnimatedSeries'', when they discovered KevinConroy's magnificent singing voice quite by accident.

** [[FinalFantasy George Newbern]] replaced [[Series/{{Wings}} Tim Daly]] as Superman [[TalkingToYourself and Bizarro]] and [[{{Series/Smallville}} Michael Rosenbaum]] replaced [[Series/DiagnosisMurder Charlie Schlatter]] as Flash.

** While most of the Jokerz from ''BatmanBeyondReturnOfTheJoker'' retained their voice actors for "The Once and Future Thing, Part 2", AdamBaldwin replaced HenryRollins as Bonk and DeeBradleyBaker replaced FrankWelker as Woof's growls. In "Part 1", Baldwin also replaced [[{{Film/Deliverance}} Bill McKinney]] as JonahHex.

** According to the commentary track for ''SupermanDoomsday'', JamesMarsters was almost the voice of GreenArrow, but had to bow out at the last second.

** Orm was supposed to return as Ocean Master later in the series, but it never happened.

* ScrewedByTheNetwork - The show consistently put out some of CartoonNetwork's best ratings in spite of the fact that it was rarely advertised, chronically shoved into unusual timeslots (six in the evening on a Saturday?!), and only aired once a week (most of Cartoon Network's other shows at this time aired reruns several times a week).

* ActorAllusion: In ''The Once and Future Thing'', Terry as Batman is confronted by British soldiers who yell "fire at will!" Terry is played by Will Friedle.

** [[{{Series/Scrubs}} John C. McGinley]] voicing The Atom, Michael Ironside as Darkseid, [[StarTrekTheNextGeneration Michael Dorn]] as Kalibak (reprising the role and he had voiced Steel on ''WesternAnimation/SupermanTheAnimatedSeries''), as mentioned EdAsner as Granny Goodness, [[StarTrekVoyager Robert Picardo]] as [=AMAZO=], [[{{WesternAnimation/Gargoyles}} Keith David]] as Despero, [[Film/ANightmareOnElmStreet Robert Englund]] as Felix Faust, [[StarTrekDeepSpaceNine Jeffrey Combs]] as the Question, pretty much the entire cast of ''Series/{{Firefly}}'', and, well, just see the pages for ''WesternAnimation/SupermanTheAnimatedSeries'' and ''WesternAnimation/BatmanTheAnimatedSeries'', as most of their voices ended up here too, plus so many more mainstream celebs that a full list would fill half this page.

** PhilLaMarr is Comicbook/GreenLantern, {{Steel}}, and STRIPE, and {{Static|Shock}}. [[Series/{{Alias}} Marcus Dixon]] is J'onn J'onzz and [[WizardsOfWaverlyPlace Theresa Russo]] is Hawkgirl.

** [[StarTrekDeepSpaceNine Weyoun]] is now a conspiracy buff.

** Famously averted with Batman. [[http://www.youtube.com/watch?v=uoRundeX6O0 Yes, really]]. This is something the producers have been ''dying'' to work into the show ever since ''BatmanTheAnimatedSeries'', when they discovered KevinConroy's magnificent singing voice quite by accident.

** [[FinalFantasy George Newbern]] replaced [[Series/{{Wings}} Tim Daly]] as Superman [[TalkingToYourself and Bizarro]] and [[{{Smallville}} Michael Rosenbaum]] replaced [[Series/DiagnosisMurder Charlie Schlatter]] as Flash.

** Series regulars PhilLaMarr (Green Lantern) and [[WizardsOfWaverlyPlace Maria Canals]] (Hawkgirl) replaced respectively [[StarTrekTheNextGeneration Michael Dorn]] and Lori Petty as Steel and Livewire, also respectively (though Dorn did reprise his role as Kalibak).
** [[StarTrekDeepSpaceNine Rene Auberjonois and Armin Shimerman]] respectively replaced Robert Morse and [[{{Everwood}} Treat Williams]] as, again respectively, Desaad and Professor Milo (though Auberjonois voiced Desaad on ''SuperFriends'', so it's still a reprisal).

** The BirdsOfPrey would have starred in an episode of ''Justice League Unlimited''. In a [[BroadStrokes semi-retelling of the origin of Oracle and the team]] there was originally a plan for {{Comicbook/Batgirl}} to be hospitalized in an episode and, unable to finish the mission she was on when she was injured, she would contact Huntress and Black Canary to help her finish the job while supervising them over their radios. The "Bat-Embargo," which was a moratorium on using certain Batman-related characters after the premier of ''WesternAnimation/TheBatman'' and the production of ''[[TheDarkKnightSaga Batman Begins]]'', meant that Batgirl had to be written out of the episode and the story was re-written and expanded into "Double Date". The episode still featured Huntress and Black Canary, but also included their "dates" TheQuestion and GreenArrow.

** In "Metamorphosis" the CorruptCorporateExecutive villain is voiced by Earl Boen, who sound a lot like [[MonkeyIsland [=LeChuck=]]] when he's being scheming.

** Dr. Destiny is [[WilliamAtherton Walter]] [[{{Ghostbusters}} Peck]].

** Green Lantern shares a name with real-life ''TheDailyShow'' host Jon Stewart, though with different spelling. A popular [[WildMassGuessing WMG]] is that it is [[SecretIdentity more than a coincidence]]...

* TheOtherDarrin - [[FamilyGuy Chris Cox]] replaced [[{{Series/CSI}} George Eads]] as Captain Atom and [[Anime/TransformersRobotsinDisguise Bob Joles]] replaced [[Film/TheLordOfTheRings John Rhys-Davies]] as Hades. Regarding characters from other series in the DCAU who also appeared in JL...

** [[ThePretender Michael T. Weiss]] replaced [[{{Titanic}} Billy Zane]] as Jason Blood and Etrigan.
** [[TheMummyTrilogy Oded Fehr]] and JenniferHale replaced [[StElsewhere George DelHoyo]] and Jennifer Lien respectively as Doctor Fate and Inza, also respectively. Hale also replaced [[EarthGirlsAreEasy Julie Brown]] as Zatanna.

** [[{{Seinfeld}} Brian George]] replaced [[BladeRunner Brion James]] after Parasite due to [[AuthorExistenceFailure James's death]]. [[Film/{{Transformers}} Robert Foxworth]] replaced [[WesternAnimation/AvatarTheLastAirbender Victor Brandt]] as Professor Hamilton.

** While most of the Jokerz from ''BatmanBeyondReturnOfTheJoker'' retained their voice actors for "The Once and Future Thing, Part 2", AdamBaldwin replaced HenryRollins as Bonk and DeeBradleyBaker replaced FrankWelker as Woof's growls.

** Amy Acker, best known as [[{{Angel}} Fred and Illyria]], was the Huntress. Giselle Loren, who voiced Buffy in the video game of ''BuffyTheVampireSlayer'' was Stargirl. Alexis "Wesley" Denisof was Mirror Master.

** In "Starcrossed" (and then "Hunter's Moon", and [[{{Reincarnation}} after a fashion]] "Ancient History"), [[TheDragon Lt. Kragger]] is [[PiratesOfDarkWater Ioz]]--much less {{loveable|Rogue}}, though.

** [[{{Entourage}} Ari Gold]] is Ralph Dibny, Elongated Man.

** Scott Rummell and CoreyBurton replaced [[CrossingJordan Migeul Ferrer]] respectively as Aquaman and Weather Wizard. Burton also replaced [[BatmanBeyond Sherman Howard]] as Steppenwolf, [[AustinPowers Michael York]] as Kanto, and briefly [[Series/{{Heroes}} Malcolm McDowell]] as Metallo and Bud Cort as Toyman, though Malcolm and Cort would later reprise their respective roles.

** [[SupermanTheAnimatedSeries Mxyzptlk]] was set to appear, but the production team couldn't find a good way to fit him into the story.
** Orm was suppose to return as Ocean Master later in the series, but it never happened.

** [[SupermanTheAnimatedSeries Mxyzptlk]] was set to appear, but the production team couldn't find a good way to fit him into the story.

** After ''TheBatman'' began airing during the ''Unlimited'' phase, all major characters from that property other than Batman himself were suddenly verboten in ''JLU''; this was referred to as the "Bat-Embargo" by fans. Similarly, the villain Black Manta was banned when ''Comicbook/{{Aquaman}}'' [[DevelopmentHell seemed]] a go for a series, as were all ''WesternAnimation/TeenTitans'' characters. Fortunately, DC has [[LoadsAndLoadsOfCharacters plenty of characters to use]]. As a result, viewers got to see more minor and obscure characters, like Deadman, Warlord, and the [[SevenSoldiers Seven Soldiers of Victory]], who otherwise would have probably been ignored.

** The BirdsOfPrey would have starred in an episode of ''Justice League Unlimited''. In a [[BroadStrokes semi-retelling of the origin of Oracle and the team]] there was originally a plan for {{Comicbook/Batgirl}} to be hospitalized in an episode and, unable to finish the mission she was on when she was injured, she would contact Huntress and Black Canary to help her finish the job while supervising them over their radios.

** Skeets, BoosterGold's robot sidekick, is voiced by BillyWest, in pretty much the exact same voice the actor uses for [[{{Futurama}} Fry]].
** And how can we forget that Superman (George Newbern) is [[FinalFantasyVII Sephi]][[KingdomHearts roth]]?

** JenniferHale voiced Black Siren, Giganta, Killer Frost, Zatanna, and Inza. Her ''KnightsOfTheOldRepublic'' and ''VideoGame/MassEffect'' co-star, Raphael "Carth Onasi" Sbarge, voiced Deadman.

** "The Once and Future Thing, Part 1: Weird Western Tales" was filled with this. {{Adam|Baldwin}} "[[Series/{{Firefly}} Jayne]]/[[{{Chuck}} Casey]]" [[AdamBaldwin Baldwin]] was JonahHex, Ben "[[Series/{{Farscape}} John Crichton]]/[[StargateSG1 Cameron Mitchell]]" Browder was Bat Lash, Jonathan "[[KingOfTheHill John Redcorn]]" Joss was Ohiyesa Smith, Nestor "[[{{Series/Lost}} Richard Alpert]]/[[TheTick Batmanuel]]/[[TheDarkKnightSaga Mayor of Gotham City]]" Carbonell was El Diablo, and Ed "[[Film/MenInBlack Kay]]" O'Ross was Tobias Manning[[strike:/Terra-Man]].

** The JusticeSocietyOfAmerica was planned to appear in "Legends", which was an AffectionateParody of TheGoldenAgeOfComicBooks. This idea went so far as to have character designs and promotional stills produced, but they were forced to transform the Society into the Justice ''Guild'' of America by DC Comics, who said they could not use the original characters.

*** The direct-to-DVD film ''[[JusticeLeagueCrisisOnTwoEarths Justice League: Crisis On Two Earths]]'' is based on the film that was originally supposed to bridge the gap between ''Justice League'' and ''Unlimited.'' ''Justice League: Worlds Collide'' would have explained the origins of the expanded roster, the new Watchtower, and Wonder Woman's invisible jet and would have featured the Crime Syndicate as the primary villains. ''Worlds Collide'' was never produced as such, but people on the ''Crisis on Two Earths'' production team have said that the film stays within "95 percent" of the original script, and indeed it shows things like the second Watchtower under construction, the beginnings of an expanded Justice League, subtle evidence that [[spoiler: Hawkgirl recently]] left the League, and the origin of Wonder Woman's invisible jet (which made its first DCAU appearance two episodes into ''Unlimited'').

** There were plans to make a crossover with ''[[WesternAnimation/TeenTitans Teen Titans]]'', but the idea was dropped because the writers couldn't come up with a good story that would fit both shows' different style.

** [[{{A Goofy Movie}} Max Goof]] is that recurring reporter.

** The JusticeSocietyOfAmerica was planned to appear in the ''Justice League'' episode ''Legends'', which was an AffectionateParody of TheGoldenAgeOfComicBooks. This idea went so far as to have character designs and promotional stills produced, but they were forced to transform the Society into the Justice ''Guild'' of America by DC Comics, who said they could not use the original characters.

*** The first was ''A Better World,'' an episode of ''Justice League'' where the Syndicate was replaced by the Justice Lords, a more direct mirror image of the League which featured [[EvilTwin alternate versions of the same characters]], rather than villains who were merely similar in theme and power.

** The BirdsOfPrey would have starred in an episode of ''Justice League Unlimited''. In a [[BroadStrokes semi-retelling of the origin of Oracle and the team]] there was originally a plan for {{Batgirl}} to be hospitalized in an episode and, unable to finish the mission she was on when she was injured, she would contact Huntress and Black Canary to help her finish the job while supervising them over their radios. The "Bat-Embargo," which was a moratorium on using certain Batman-related characters after the premier of ''TheBatman'' and the production of ''BatmanBegins'', meant that Batgirl had to be written out of the episode and the story was re-written and expanded into ''Double Date''. The episode still featured Huntress and Black Canary, but also included their "dates" TheQuestion and GreenArrow.
** The commentary for ''The Return'' reveals that, when ''Starcrossed'' was scripted, the writers did not know where Shayera had gone after leaving the League. One theory was that she had become the resident guardian angel of a small South American village, and another was that one of the victim planets of the Thanagarians had found her seeking revenge (This story was later used in the ''Unlimited'' episode ''Hunter's Moon''). Eventually they decided that she had sought sanctuary with Dr. Fate, and this lead to the double meaning of the title ''The Return''.
** Lastly, a minor cameo instead of a plot-important appearance, the writers originally wanted a Joker cameo in ''This Little Piggy'' for a brief moment of comic relief. After Diana [[spoiler:had been turned into a pig]], Batman would be walking down the street with her and would pass the Joker preparing to commit a crime with his gang. The Joker, in the middle of preparing a heist and laying out his convoluted plan to deal with Batman, would see Batman [[spoiler:holding and consoling a pig]] and would stare at it in DullSurprise, then throw his hands in the air and abandon the entire scheme. Sadly, this scene (Which might very well have been the single greatest scene ''ever animated''), had to be dropped from the episode for a variety of reasons, including time and pacing problems.

** [[{{Scrubs}} John C. McGinley]] voicing The Atom, Michael Ironside as Darkseid, [[StarTrekTheNextGeneration Michael Dorn]] as Kalibak (reprising the role and he had voiced Steel on ''SupermanTheAnimatedSeries''), as mentioned EdAsner as Granny Goodness, [[StarTrekVoyager Robert Picardo]] as [=AMAZO=], [[{{Gargoyles}} Keith David]] as Despero, [[NightmareOnElmStreet Robert Englund]] as Felix Faust, [[StarTrekDeepSpaceNine Jeffrey Combs]] as the Question, pretty much the entire cast of ''{{Firefly}}'', and, well, just see the pages for ''SupermanTheAnimatedSeries'' and ''BatmanTheAnimatedSeries'', as most of their voices ended up here too, plus so many more mainstream celebs that a full list would fill half this page.

** The Joker's new gang in "Wild Cards" are all voiced by the ''TeenTitans'' actors. It is really kind of weird.
** And HOW, oh, HOW did everyone forget Michael Rosenbaum, who voices the Flash AND plays [[{{Smallville}} Lex Luthor]]?
*** Even better is how this is played for laughs in "The Great Brain Robbery", in which Flash and Luthor switch minds!!!
