* AllStarCast: All three films feature Creator/ChristianBale, GaryOldman, MichaelCaine, MorganFreeman and Creator/CillianMurphy, on top of:
** LiamNeeson, Katie Holmes, Tom Wilkinson and Rutger Hauer in ''Batman Begins''.
** Creator/HeathLedger, Aaron Eckhart, MaggieGyllenhaal, and Eric Roberts in ''The Dark Knight''.
** And Creator/AnneHathaway, TomHardy, Creator/JosephGordonLevitt, and MarionCotillard in ''The Dark Knight Rises''.
* {{Fake American}}s: In the first movie, Katie Holmes and Morgan Freeman are the only actual Americans, amid the Welsh-born Englishman Christian Bale, the English Gary Oldman and Tom Wilkinson, and the Irish Cillian Murphy (and Liam Neeson, but Ra's isn't American anyway). There are more real Americans in the second film, but the Joker is played by Australian Heath Ledger. (We can't be sure of the Joker's nationality, but he speaks with a Chicago accent).
* FanNickname: The "Nolanverse" is a common fan-used name for the trilogy.
* HeyItsThatGuy:
** [[{{Lost}} Richard Alpert]] is the mayor of Gotham City. Said mayor is also, in a ShoutOut, [[{{TheTick}} Batmanuel]].
** Clearly, [[{{Inception}} something went wrong with]] [[Creator/CillianMurphy Robert Fischer's]] inception...
** [[PrisonBreak Wade Williams]] has a quick cameo. Maybe he could've said hi to William Fichtner beforehand. Or maybe he should've worn a [[BatmanUnderTheRedHood black mask]].
** Comissioner Gordon is [[Franchise/HarryPotter Sirius Black!]]
*** Considering Gordon's position as straight cop trying to fence off corrupt ones, it's kinda funny that he was once [[Film/TheProfessional an extremely corrupt cop]] himself.
** Gambol is {{ComicBook/Spawn}}.
** Salvatore Maroni works for [[{{Series/Heroes}} the Company.]]
** Before Stryver became VP at Daggett Industries' he [[{{Series/Torchwood}} caught aliens for a living]].
** Teal'c
** Will LaMontagne
* HeyItsThatVoice:
** A lot of familiar voices are heard in ''Gotham Knight'', most prominently [[TheDCAU Kevin Conroy as Batman]].
** [[{{CSI}} Gary Dourdan]] as Officer Allen, [[UglyBetty Ana Ortiz]] as Officer Ramirez, RobPaulsen as Maroni, Creator/KevinMichaelRichardson as Lucius Fox, [[Series/{{NCIS}} David "Ducky" McCallum]] as Alfred and [[Series/{{ER}} Parminder Nagra]] as Cassandra.
** The Japanese dub of both the movies and ''Gotham Knight'' had [[TheOtherDarrin different voice casts]] between them (especially from ''Batman Begins'', who had three different voice casts, depending from the network who broadcasted the movie and the DVD/BD release):
*** Batman [[TomoyukiDan is]] [[Anime/MobileSuitVictoryGundam Chronicle Asher]] in the DVD/BD release, in the NTV (Nippon Television) version, [[Creator/HirokiTochi he is]] [[MobileSuitGundam00 Lasse Aion]] and [[MobileSuitGundamAGE Grodek Ainoa]] and in the Fuji TV version, [[HirokiTakahashi he is]] [[VideoGame/StreetFighterIV Ryu]], [[SchoolRumble Kenji Harima]] and [[VideoGame/SuperRobotWarsMX Hugo Medio.]] Creator/TesshoGenda reprise his role as Batman from the dub of ''WesternAnimation/BatmanTheAnimatedSeries'' in the Japanese dub of ''Gotham Knight'', along with Creator/ShinichiroMiki as his younger self. And as of Joker? [[MemeticMutation Prin]][[{{Gundam 00}} ce]] [[Creator/KeijiFujiwara Ali]]. In the Japanese dub of ''The Dark Knight Rises'', Selina/Catwoman [[MieSonozaki is]] [[Videogame/StreetFighterIV Crimson Viper]] and Bane [[KazuhiroYamaji is]] [[Series/KamenRiderBlade Kei Karasuma.]]
* InspirationForTheWork: Christopher Nolan has [[http://www.ign.com/articles/2007/12/06/ign-interviews-christopher-nolan gone on record]] that ''Film/{{Heat}}'' was a big inspiration for his trilogy. Bruce's relationship strain with Rachel mirrors [[{{Expy}} Vincent and Justine's.]] The heist in ''The Dark Knight'' is also a homage to the opening heist in ''Heat.''
* [[LyingCreator Lying Creator and Actors]]: [[spoiler:The statements that Talia al'Ghul and Robin would not be in the films was supported (by lying, or simply silence) by the actors who ''played'' Talia al'Ghul and Robin.]]
** [[spoiler:Earlier on, Nolan also claimed that Robin would never appear in the series because Bruce Wayne himself was just starting out, and Robin "would still be a kid at this time". This one's at least true FromACertainPointOfView: there's a TimeSkip before ''Rises'', and Dick Grayson--the character almost everyone ''assumed'' Nolan was referring to--is replaced by the CompositeCharacter Robin John Blake.]]
* WhatCouldHaveBeen:
** Among those who auditioned for the role of Bruce Wayne/Batman? Cillian Murphy.
** A video game tie-in to ''The Dark Knight'' was listed as "In Development" for several months before and after the movie came out, with GaryOldman even discussing it in an interview with G4, but it was ultimately scrapped. The developers may have felt that releasing a video game with players beating up [[HeathLedger a recently deceased actor]]'s digital avatar [[TooSoon would have been in poor taste]].
** There were originally going to be more sequels, but after the death of HeathLedger they decided to make TheDarkKnightRises the GrandFinale to the series.
** A large part of TheDarkKnightRises was going to be a subplot involving the Joker on trial for the crimes committed in the second film, essentially providing payoff for the "Batman and Joker fighting forever" idea set-up at the end of ''Dark Knight''. After Ledger's death it was decided to simply cut Joker out entirely rather than recast him, since Ledger would be such a ToughActToFollow.
