!! For both:
* AngstWhatAngst:
** Franchise/{{Superman}}, upon learning that he's dying, merely proceeds to quietly put his affairs in order. Then again, there are quite a few hints he isn't taking it as well as he seems - his refusal to tell anybody about it, and his breakdown while under the effects of black kryptonite, for instance. He is, after all, an absolute pro at hiding his emotions.
** [[spoiler:The same applies to Comicbook/LexLuthor concerning his imminent execution. Though in his case, it's very clear his escape was already planned.]]
* MemeticMutation: Lex's SpitefulSpit at Superman right after the Man of Steel expressed his belief that he still had good in him led to people joking about how that spit was the last of said good.
* SacredCow: Don't criticize either the comic or the movie in a public forum. This is wildly considered not only as one of the greatest (if not '''the''' greatest) Superman stories of all time, but one of the greatest '''comic stories''' of all time, and the movie is considered one of the greatest adaptations.
* TheyWastedAPerfectlyGoodPlot: Lois gets Superman's powers for a day and expresses great excitement at the prospect of fighting crime alongside him, but she unfortunately doesn't get to put her powers to much use. Though the chapter introduces two major threats in the form of the Subterranosauri invasion and the Ultra-Sphinx, the former is instantly thwarted by Samson and Atlas' sudden appearance; whereas the latter reduces Lois to a DamselInDistress until Superman bests the monster in a battle of wits.

!! For the [[ComicBook/AllStarSuperman comic]]:
* AlternativeCharacterInterpretation: Does Jimmy know that Clark is Superman? His lines after Superman blasts Luthor with the gravity gun can either be seen as him genuinely guessing where Clark Kent is, or he's just saying it so that Luthor doesn't realize the truth through his super-hearing.
%%** An EpilepticTree-ish one about Leo Quintum has become an almost essential part of the story's mythos on the internet after being pitched in [[http://mountainofjudgment.blogspot.com/2008/09/all-star-superman-xs-and-os.html an article]] by Cole Moore Odell. ''If you've finished the story'', check it out.
%%** "[[http://techland.time.com/2010/11/02/the-secret-of-all-star-superman/2/ The Secret of All-Star Superman."]]
* AlternativeJokeInterpretation: The revelation from Bizarro Green Lantern that Bizarro Batman was shot by his parents can be interpreted two ways: Either Bizarro Batman doesn't exist because he was shot to death by his parents as a child, or Bizarro Batman became a bat-costumed vigilante while his parents were still alive and his absence from the Unjustice League was because his parents shot him to death recently.
* CrossesTheLineTwice: The entire concept of "[[BlackComedy Bizarro Batman]]" is so horrifically twisted and wrong that it's hilarious: He doesn't show up with the other members of the Unjustice League because ''his parents shot him dead.''
%%* EnsembleDarkhorse: Nasthalthia Luthor, despite being a previously forgotten Bronze Age Comicbook/{{Supergirl}} villain and making only a few appearances.
* EpilepticTrees: Many believe Leo Quintum is [[spoiler:Lex Luthor, having travelled backward in time from after the end of the series where he briefly copied Superman's powers and [[GoMadFromTheRevelation Went Sane From The Revelation]].]]
* GeniusBonus: Superman's ancestor Bar-El ends up as the effective warden of Krypton's maximum security prison The Phantom Zone. Scotland's biggest prison is in Grant Morrison's hometown Glasgow, [[https://en.wikipedia.org/wiki/HM_Prison_Barlinnie HMP Barlinnie]] informally known as the Bar L.
* IKnewIt: A fan at a convention Q&A session asked Grant Morrison if Jimmy Olsen was a SecretSecretKeeper who had worked out that Superman and Clark Kent were the same person and Morrison confirmed it.
* OneSceneWonder: Regan, the troubled teen goth girl who Superman touches down from the ledge, is on only one page, yet that one page is remembered for providing one of the most touching moments in comic book history.
* SignatureScene:
** Superman saving the suicidal teen, a powerful moment often regarded as one of the greatest Superman (if not ''superhero'') moments of all time. The page where this happens is frequently shared in online forums and received a MythologyGag in ''WesternAnimation/JusticeLeagueDarkApokolipsWar''.
** The [[AdaptationDistillation streamlined]] origin retelling is one of the most famous pages of the book, for succinctly summarizing Superman's backstory in four panels.
** The [[http://www.dccomics.com/sites/default/files/GalleryGraphicNovels_1900x900_AllStarSuperman_52af9dd1ba02e7.99277890.jpg image]] of Superman flying under the sun, which later was redrawn and used as the cover for the animated feature.
* TheyWastedAPerfectlyGoodCharacter: The series is an absolute distillation of everything great about Superman and his mythos... except for Lois Lane. While the book makes some throwbacks to Silver Age Lois shenanigans like her suffering from {{Superdickery}} and receiving superpowers, the book never actually goes into detail about exactly ''why'' Superman fell in love with this woman besides vague lip service about "some things [he] just can't help".
* WinBackTheCrowd: In the sense that the story allowed Morrison to use some of the concepts from their aborted ''Superman 2000'' pitch and bring back their ''ComicBook/DCOneMillion'' continuity.

!! For the [[WesternAnimation/AllStarSuperman film]]:
* SugarWiki/AwesomeMusic: Christopher Drake's [[https://www.youtube.com/watch?v=EphFQelYhp8 fanfare]] rivals John Williams' ''Film/{{Superman|TheMovie}}'' fanfare.
* BigLippedAlligatorMoment: Quite a few scenes in the middle, particularly the one with Samson, come absolutely out of left field, have no relevance to the plot, and are never mentioned again. While comic readers know that these are whole stories from the comic, they are very poorly implemented into the movie.
* CompleteMonster: [[RoboticPsychopath Solaris the Tyrant Sun]] is a gigantic computer that wanders the cosmos, consuming stars for fuel and leaving the inhabited planets to die. Contacted by ComicBook/LexLuthor to assist him in his master plan to defeat a dying Superman, Solatis turns the Sun red in an attempt to depower the Man of Steel. Supes counteracts this and leads an army of sapient robots to battle Solaris, but he destroys the army in one blast before announcing his plan to [[TheStarscream betray Luthor]], consume the Sun and force the Earthlings to [[AGodAmI worship him as a deity]] or freeze to death in eternal darkness. Superman then tries to feed the Tyrant Sun to a Sun-Eater, but Solaris destroys it. Before Superman destroys the mad machine, Solaris turns the Sun blue [[TakingYouWithMe to spite Superman by destroying his people]].
* GeniusBonus: Superman tells his robots to set their receivers to 430 terahertz to be able to hear Solaris. While usually expressed as wavelength, 430 terahertz is the frequency of red light in the electromagnetic spectrum, meaning that Solaris "speaks" with signals in the red light he emits, much like a radio station broadcasts in radio waves that you would be able to hear if you tune your radio to a specific frequency.
* HarsherInHindsight: As mentioned on the main page, writer Dwayne [=McDuffie=] died suddenly of complications from emergency heart surgery the day before the film was released on DVD. Made all the more poignant because the film concerns Superman facing his mortality, and he had been giving [[http://www.paleycenter.org/2011-spring-all-star-superman-ny/ interviews]] [[http://www.paleycenter.org/2011-spring-all-star-superman-la/ about the film]] mere days before.
* TheyChangedItNowItSucks: The film changes Solaris' fate from [[spoiler: being captured and reprogrammed to being ''executed'' (maybe) by Superman,]] replacing [[PreMortemOneLiner one of Superman's most memorable lines]] in the process. It also changes the pacing of the prison riot so that Clark fails to save some convicts from the Parasite. The adaptation also cuts two of the comic's most affecting moments; where Superman [[spoiler:gets to say a final goodbye to his father]], and the famous scene with the attempted suicide.
