History YMMV / TheStrangeCaseOfDrJekyllAndMrHyde

** The pronunciation of "Jekyll". The correct (and little-known) pronunciation is "Jee-kul", in accordance with Scottish rules of pronunciation (the novella's author was Scottish, and "Jekyll" is a real Scottish surname). The 1941 film adaptation popularized the pronunciation "Jeck-ul", and [[Creator/MetroGoldwynMayer MGM]] bought the rights to [[Film/DrJekyllAndMrHyde1931 the 1931 adaptation]] (which did pronounce Jekyll's surname as "Jee-kul") and [[ScrewedByTheLawyers destroyed every print they could find]] [[MoneyDearBoy to avoid competition]]. The 1931 film was believed to be lost for several decades, and pretty much every film and stage play adaptation after 1941 pronounced Jekyll's surname as "Jeck-ul" to the point that the correct pronunciation is hardly known anymore outside of Scotland.
* FandomEnragingMisconception: Do ''not'' pronounce the titular doctor's surname as "Jeck-ul" in front of a Scottish fan. It is supposed to be pronounced "Jee-kul"; Creator/RobertLouisStevenson was Scottish, and "Jekyll" is a real Scottish surname.

* CommonKnowledge: There are a few widespread misconceptions about the novel. For example, the fact Jekyll and Hyde were one and the same was a ''twist'' is not often known (probably because the story is so famous), and despite multiple adaptions including this element, there were no love interests in the original story (in fact, there were no named female characters at all).

** A line Jekyll makes about Hyde growing in stature, as though conscious of a more generous tide of blood. Does he mean Hyde would have grown to hulk-like proportions or that he's just becoming healthier compared to the skinnier dwarf form he starts off as compared to the more hearty stocked Jekyll?

* ValuesResonance: As mentioned on the main page, a lot of modern-day readers see parallels between Hyde and [[{{GIFT}} those who use anonymity on the internet as an excuse for behaving badly without consequences]], with some likening Jekyll to a person's normal account and Hyde to an alt account they use for {{Trolling}}.

* AllThereIsToKnowAboutTheCryingGame: The work is [[MainstreamObscurity well-known by name]], but all that most people have heard about it is [[JekyllAndHyde the twist ending]]. Many do not even know that the dual identity story was originally a twist at all, and most newer adaptations treat it as a foregone conclusion. Some even make Hyde himself some sort of ugly were-monster rather than just a really evil man (although everyone who meets Hyde reacts as if he's horribly ugly and deformed, there is nothing specific about his looks to cause this).

* ItWasHisSled: The original story is a mystery about what connection the upstanding Jekyll could have to the shady Hyde. Pretty much everyone nowadays already knows the answer; Jekyll and Hyde are one and the same, the result of Jekyll taking a potion that split him into two selves, one normal and one totally evil. Often enough, [[AllThereIsToKnowAboutTheCryingGame the twist is the only thing they know about the story]].

* WhatDoYouMeanItWasntMadeOnDrugs: Inverted. Stevenson wrote the first draft of the story in one-sitting during a speed binge.

* SelfFanservice: Mr. Hyde is described in the book as "dwarflike" and with some sort of facial feature that had him dip into UncannyValley territory, and some adaptations turn him into a hulking monster. A lot of fan-art (and some other adaptations) prefer to portray him as being a slightly more deranged-looking-yet-[[EvilIsSexy sexier]] version of Jekyll. The good doctor himself also gets this, often being made younger (and [[{{Bishonen prettier]] to better contrast the more rugged Hyde) than he was in the novel.

** It's really easy to read some Utterson/Jekyll into the former's concern for the latter, with his fears that Hyde was Jekyll's son or lover, and was using that to blackmail him. Given the [[ValuesDissonance time period]] where the book was written, this was almost definitely not intentional.

* MoralEventHorizon: Clearly, when Hyde brutally murders Sir Danvers Carew for absolutely no reason, he has reached this point. Even Jekyll denounces him.

* CommonKnowledge: There are many common misconceptions about the novel, the foremost being that Jekyll and Hyde being the same person was a twist, and there are no love interests or nominal women at all.

Pretty much everyone nowadays already knows the answer; Jekyll and Hyde are one and the same, the result of Jekyll taking a potion that split him into two selves, one normal and one totally evil.

** In the book Jekyll pretty much admits that his motive for inventing the serum was nothing other than ForTheEvulz; he wants to be able to act immorally, but as Jekyll he'll always be worried about his respectable image. As Hyde he doesn't have to worry, as the worst people think of him is that Hyde might be blackmailing him (and / or could be his BastardBastard son). And keep in mind that Jekyll chooses to keep turning into Hyde ''even after Hyde severely injured an innocent child.''

* JerkAssWoobie: Jekyll, [[AlternateCharacterInterpretation if you believe he truly had good intentions.]]

** A lot of people will assume the two girlfriends are part of the book's plot as well; they were introduced in the very first stage play and added to many subsequent versions.

* UncannyValley: This is how the other characters describe Hyde and recognize that he's not quite right. They always describe him as looking "deformed" somehow, despite having no outwardly noticeable disfigurements. This is subtlety is lost on subsequent adaptations, mostly because it's hard to show on screen, and partly because EvilIsSexy sells better.

* AlternativeCharacterInterpretation: Not a full example as this is actually mused upon in the book, but the idea that the serum doesn't actually transform Jekyll into a different-looking evil man, it simply transforms him into a different-looking man, and it's the intoxication of being able to get away with any crime that leads him to act so evilly.
** Of course many adaptations, especially recent ones, decide to eschew the idea that it changes his looks at all and represent the changes purely by acting.
** In the book Jekyll pretty much admits that his motive for inventing the serum was nothing other than ForTheEvulz; he wants to be able to act immorally, but as Jekyll he'll always be worried about his respectable image (not really anything to do with conscience).

And keep in mind that Jekyll chooses to keep turning into Hyde ''even after Hyde severely injured an innocent child.''
** Also of more modern debate, about a line Jekyll makes about Hyde growing. The word used there is "stature" which has more than one meaning. Does he mean Hyde would have grown to hulk like proportions or that he's just becoming healthier compared to the much skinnier dwarf form he starts off as compared to the more hearty stocked Jekyll?

* CommonKnowledge: As noted in the intro, there are ''many'' common misconceptions about the novel.
* HarsherInHindsight: Hyde's crimes were heinous enough, but soon after the book was published, the Jack the Ripper murders took place. Even worse, one of the suspects was an actor who ''played'' Jekyll and Hyde onstage; his performance was so convincing that people began to believe it wasn't an act.
* HoYay: Too easy to read some Utterson/Jekyll into the former's concern for the latter.
** His fears that Hyde was Jekyll's lover, and was using that to blackmail him.
*** Homosexual undertones were read into the book early on, and a few of Stevenson's gay friends chided him for possibly bringing them to light at all. The recent passing of homosexual legislation up north meant that closeted homosexuality wasn't just a hot-button issue at the time, but that Stevenson could possibly have had it on the mind while writing. A closer look at the edits from the second manuscript seems to support this theory, as Utterson himself starts to read a little bit more into Jekyll and Hyde's perceived relationship. Then again, this was a time when two men could have a completely platonic [[RomanticTwoGirlFriendship Romantic Two-Man Friendship]] and not be chided for it (again, because the idea of two men having sex with each other was just too absurd for Victorian sensibilities).
*** A short story by Creator/KimNewman, "Further Developments in the Strange Case of Dr. Jekyll and Mr. Hyde", riffs on this; [[spoiler: Essentially, Hyde is a separate person. And he's Jekyll's lover.]]
* ItWasHisSled: The original story is a mystery about what connection the upstanding Jekyll could have to the shady Hdye. Pretty much everyone nowadays already knows the answer (which was a TwistEnding when the book was published)- Jekyll and Hyde are one and the same, the result of Jekyll taking a potion that split him into two selves, one normal and one totally evil. Often enough, the twist is the ''[[AllThereIsToKnowAboutTheCryingGame only]]'' thing they know about the story.
* JerkAssWoobie: Jekyll, [[AlternateCharacterInterpretation if you believe he truly had good intentions of course.]]
* MainstreamObscurity: Just ask a member of the general public to give you even a vague summary of the plot! As mentioned above, most people ''don't even know'' that the dual identity was originally a TwistEnding, and it is not uncommon to see [[Film/VanHelsing parodies]] [[Comicbook/TheLeagueOfExtraordinaryGentlemen of it]] where Hyde is literally an ogre monster- rather than simply an evil (but not even particularly ugly) man. To be fair, Hyde is described in the book as a misshapen dwarf so ugly he inspires hatred in people without them even understanding why (possibly an uncanny valley effect due to looking somewhat inhuman).
** A lot of people will assume the two girlfriends are part of the book's plot as well; they were introduced in the 1920 silent film (and if you ''really'' wanna go back, the very first basis for a lover was in the stage play version) and added to many subsequent versions.
* MisaimedFandom: Many people will use the idea of being a "Jekyll and Hyde" as an excuse for either their own bad behaviour or that of their loved ones: "The real me (Jekyll) would never do such a thing, it was this alien force (Hyde) that took over my body and made me do it." This arguably inverts the moral of Stevenson's story, where Jekyll's refusal to take responsibility for Hyde's actions was a big part of what caused things to go badly.

!! The 1988 video game provides examples of:
* NightmareFuel: The game has two endings. One of them is reached by simply getting to the church as Jekyll before Hyde. It just shows the church and the word "END" appears while the wedding march plays. A second ending, somewhat hidden, is earned by reaching Level 6 as Jekyll and then proceeding to the end as Hyde. Hyde then fights a boss "demon" at the church, and, upon beating it, turns back into Jekyll. Jekyll's able to reach the church unhindered (all the enemies disappear) and an extended cutscene of the wedding plays. "END" appears when the screen fades out after bride and groom kiss. However, after waiting a while, the music will abruptly stop and the sound effect for the bomb is played. When the bomb "explodes", lightning flashes, the word "END" appears reversed, and Mr. Hype appears as a red silhouette with what appears to be a giant cross embedded into his back. Like everything else about the game, the extended ending is unexplained, leaving it ambiguous (for the wrong reasons) as to whether or not it can be considered a "good" or "bad" ending.
** What throws this into NightmareFuel is that Hyde's silhouette in the second ending comes out of nowhere, and given what happens to Dr. Jekyll in the book, it can be implied that Hyde still "lives", or worse, that the demon he killed took over the Hyde personality. The lighter explanation is that the cross represents Jekyll finally "ending" Hyde by getting married. [[http://www.youtube.com/watch?v=PdrFR76Bs6E This video suggests the latter is a good ending]].
* TheProblemWithLicensedGames: One of WebVideo/JoueurDuGrenier 's most hated game and it's WebVideo/TheAngryVideoGameNerd's least favourite (or [[VideoGame/{{ET}} second least favourite]]) game. And he plays a ''lot'' of bad ones.
