* ActorAllusion:
** Creator/FredTatasciore [[VideoGame/SpiderManEdgeOfTime previously played J. Jonah Jameson]] before playing his DC equivalent, Perry White, here.
** When Superman goes crazy, he sounds a lot like one of George Newbern's other characters: Sephiroth from ''VideoGame/FinalFantasyVII''.
* CrossdressingVoices:
** The young Manchester Black is voiced by Creator/GreyDeLisle.
** The character credited as "kid playing Superman" is voiced by Creator/JenniferHale.
* FakeBrit:
** The young Manchester Black is voiced by Creator/GreyDeLisle, an American voice actress. Averted with the adult self, with Creator/RobinAtkinDownes having been born in England before moving to the US. [[WhatTheHellIsThatAccent Not that it really helps.]]
** Vera's voice actresses as an adult and child, Marcella Lentz Pope and Creator/TaraStrong, are both American, the latter also Canadian.
** Creator/StephenStanton voices their father, and he's also American.
* RoleReprise:
** George Newbern reprises his role as Superman/Clark Kent from ''WesternAnimation/JusticeLeague'', while David Kaufman reprises his role from the Franchise/DCAnimatedUniverse as Jimmy Olsen.
** In the French dub, several voice actors from previous adaptations reprise their roles here:
*** From ''WesternAnimation/SupermanTheAnimatedSeries'': Creator/EmmanuelJacomy as Superman/Clark Kent and Creator/VeroniqueAugereau as Lois Lane.
*** From ''WesternAnimation/AllStarSuperman'': In addition to Superman, Yoann Sover as Jimmy Olsen and Thierry Murzeau as Perry White.
* SelfAdaptation: Joe Kelly of Creator/ManOfActionStudios wrote both ''ComicBook/WhatsSoFunnyAboutTruthJusticeAndTheAmericanWay'' and this film.
* TimeShiftedActor: Robin Atkin Downes and Marcella Lentz Pope voice Manchester Black and Vera Black as adults, while Grey [=DeLisle=] and Tara Strong voice them as children.
* WhatCouldHaveBeen:
** Originally, the film was going to use the Parasite as the villain Superman refuses to take down lethally before the Elite kill him instead, but he was already used in ''ComicBook/AllStarSuperman'' (and underwent a similar fate of going on a killing spree before getting killed himself), so they went with the Atomic Skull instead.
** ComicBook/LexLuthor was also going to make an appearance like in the comic.
