History YMMV / SupermanIVTheQuestForPeace

** Creator/JonCryer claims he took the role of Lex Luthor on ''Series/Supergirl2015'' to "atone" for playing Lenny Luthor. [[EnsembleDarkhorse And boy]], [[BreakoutVillain did he atone]].

** Creator/JonCryer claims he took the role of Lex Luthor on ''Series/Supergirl2015'' to "atone" for playing Lenny Luthor. [[MagnificentBastard And boy]], [[EnsembleDarkhorse did he atone]].

** It's often forgotten that in-between films three and four we had ''Film/Supergirl1984'' which introduced us to the fact that there is a floating city full of Kryptonians still out there, one of which being Superman's cousin who is on first-name terms with both Jimmy Olsen and Lois Lane's sister. There is obvious story potential here but they do not even get a mention anywhere in this film.

* RetroactiveRecognition: Creator/JimBroadbent is arms dealer Jean Pierre Dubois.

** Lex Luthor's constant phrasing of "nuclear" as "nucular". A mispronunciation that four Presidents of the United States before and after this film[[note]]Dwight D. Eisenhower, Jimmy Carter, Bill Clinton, George W. Bush and vice president Walter Mondale[[/note]] were chastised for using.

* {{Narm}}: Nuclear Man's ridiculous, poorly looped-in roaring and snarling during the moon battle. The fight, shot mostly in slow motion for maximum awkwardness, culminates with Nuclear Man bodily lifting up Superman, planting him feet-first into the moon's surface, and then hammering him into the ground like a railroad spike, complete with appropriate sound effects.

* SoBadItsGood: Aside from the combination of sincerity and cheese that usually earns a movie the designation, it's quite easy to argue that ''Superman IV'' is a better comedy film than ''Film/SupermanIII''; it has {{Narm}} in spades, and Unintentional Humor beats Failed Gags every time. The [[IncomingHam mere presence]] of Creator/GeneHackman can make anything a little better, and his HamAndCheese here, as both clever Lex Luthor ''and'' the voice of [[BrainlessBeauty all-brawn, no-brains]] Nuclear Man, is quite tasty. Creator/JonCryer's TotallyRadical Lenny Luthor is more bearable than it otherwise would have been with Hackman to play off. And if nothing else, despite how bad the film otherwise is, Reeve still gives it his all, showing why even to this day, when it comes to "Actors who played Superman", people still say "There's Christopher Reeve, and there's everybody else".
