!!For the Board Game
* MemeticMutation: "It was [person] in the [location] with the [weapon]"
* PlotHole: If the weapon is the Revolver, then how did no one hear the gunshot? The 2008 SettingUpdate closes this hole by swapping the Revolver for a semi-automatic Pistol with a suppressor clearly attached.
* ReplacementScrappy: Dr. Orchid, for Mrs. White. It ''really'' doesn't help that Hasbro put it in her backstory that she's the [[RememberTheNewGuy adopted daughter of Dr. Black]], and that the character she replaced was [[spoiler:KilledOffForReal]].
* TheyChangedItNowItSucks: The 2008 "modernized" version of the game garnered this reaction to some, which is probably why said changes were dialed back in the newer releases of the game to the classic version.
* UnwinnableByInsanity: An incorrect accusation takes a player out of the game. This trope comes into play if every participant except one does this at which point a botched accusation must be avoided at all costs.
!!For the Movie
** There's a good deal of debate surrounding Mr. Green's actual sexuality. [[spoiler:In the third ending his last line is "I'm going home to sleep with my wife." A joke that he was straight all along, or is he just keeping up the facade now that other people are around?]] Though considering he outs himself, the latter might be unlikely.
** Wadsworth. [[spoiler:In the Scarlet and Peacock endings where he's working for the FBI is he deliberately making it harder on Boddy's victims and not protecting the accomplices out of some sense of justice? In the ending where he's Mr. Boddy is he behaving the way he does throughout the movie to torment his victims?]]
* SugarWiki/AwesomeMusic: John Morris' score [[https://www.youtube.com/watch?v=hAUeEGdmFs4 is often criminally overlooked]].
* BetterOnDVD: With its 3 endings, which not only heavily encourage re-watching to work out the various solutions, but also make a trip to a theater showing only one ending less satisfying, ''Clue'' seems specially designed for [=DVD=] viewing. Even though it was made almost a decade before the medium was invented.
** Of course when it was released on VHS, all three endings were shown back to back like it is available on the DVD. However the DVD has the option to choose a random ending.
** The way that they did it was that the multiple endings were supposed to be spread out over the movie's run, or mixed up and shown randomly... so that if you wanted to see the other two endings, you had to ''go see the movie again.'' Twice. At least.
** Seeing the film again, one will notice Wadsworth's reaction to Mr. Green revealing his blackmail without letting Wadsworth out him. He's confused and checks the blackmail to see if Green's there, [[spoiler:the blackmail unfamiliar to him and possibly planted by the FBI.]]
** "Da-da-da-dum-dum-dum! I! Am! Your singing telegram--" *BANG*
** Also:"...Oh, life could be a dream (sh-boom)...If I could take you up in paradise up above (sh-boom)..."
** "I said shake, rattle and roll! I said shake, rattle and roll!"
* EnsembleDarkhorse: Yvette (for [[MsFanservice obvious reasons]]).
* HilariousInHindsight: Creator/RogerEbert offered this in his review:
--> Here's my suggestion: Since this movie is so short anyway (88 minutes), why doesn't the studio abandon the ridiculous multiple-ending scheme and show all three endings at every theater? It would be more fun that way.
* IncrediblyLamePun: Wadsworth's pun about Hoover
-->'''Professor Plum''': But is the FBI in the habit of cleaning up after multiple murders?
-->'''Wadsworth''': Of course. Why do think itís run by a man called Hoover?
** Wadsworth, the butler. In all three endings. [[spoiler:In the first two endings Wadsworth, actually an FBI agent, set up the entire scheme in order to implicate the killer in a conspiracy and take her down. In the third ending, Wadsworth is actually Mr. Boddy and used the guests to kill off the informants who gave him everything he used to blackmail them; with each of the guests now guilty of murder and his informants all dead, he then plans to extort even '''more''' blackmail money from them.]]
** Mr. Green in the third. [[spoiler:He successfully passes as one of the blackmail victims and passes for a clumsy fool and homosexual. In truth, he IS the FBI agent, shoots Wadsworth when he reveals himself, has all the others arrested, then announces that he is "Going home to sleep with his wife!"]].
** "FLAMES on the side of my face"
** "That's how it could have ended. But how about this?"
*** "Here's what really happened."
** "And, to make a long story short (TOO LATE)..."
** "Communism was just a red herring."
** "There's just one thing I don't understand (One Thing?!)..."
* OneSceneWonder: Jane Wiedlin as "your singing telegram (BANG!)".
* PlotHole: [[spoiler:In her murderer ending, Mrs. Scarlet plans on blackmailing all of the guests for government information, including Mrs. White just because her husband was a nuclear physicist. Ignoring the fact Mrs. White's husband is dead and (seeing as she's had 5 husbands and this was her second) has been for presumably a while, why would the wife of a nuclear physicist have access to any of his highly classified info regarding a secret fusion bomb?]]
** A point could be made for [[spoiler:Miss Scarlet in her ending as the murderer. Not so much for anything to do about miscounting the bullets, but that she made her case to extort secrets from the other guests at gun point with the threat of blackmail to keep them in line. Problem is, she then plans to kill Wadsworth on the spot ... with a gun that only has one bullet left. The moment she wasted her bullet on him and loses her immediate leverage, what was to stop any of the other guests from just grabbing her and subduing her?]]
** After the first couple murders, Wadsworth plans on locking up the remaining weapons so they can't be used to murder anyone else. This is all great in theory ... but he doesn't lock up the Candlestick or the Knife that have already been used. Just because they were used once to kill someone, it doesn't make them any less deadly to be used again. Alternately, the killer in all three endings ''also'' never thinks about this, and has to steal the key from Wadsworth (or plan on breaking open the cupboard) instead of just picking up one of the previously used weapons. Or for that matter [[ImprovisedWeapon just picking up one of the numerous candlesticks, kitchen knives, pieces of lead pipe, and other potential weapons that are lying randomly around the house and are not locked in the cupboard]].
