!!The film
* AllStarCast: Well, yeah.
* BoxOfficeBomb: The film only grossed $14.6 million on a $15 million budget and was one of the big flops of the 1985 Christmas season (possibly due to the MultipleEndings gimmick). However, it became a CultClassic on video and cable (where all three endings appeared together).
* CastingGag:
** Mr. Boddy can't stay for very long. In fact, he's just [[StealthPun Lee Ving]].
** This isn't [[Film/MurderByDeath the first time]] Mrs. Peacock's been involved in a manor murder mystery.
* DevelopmentHell: The remake, which has been on and off in production since the late 00s, and had Gore Verbinski attached at one point. News of production began popping up again in 2016 however.
* ThrowItIn: The famous "I hated her ''sooooooooooooooooo'' much... Flames! Flames on the side of my face! Breathing... breathe-... heaving breaths..." scene resulted from Madeline Kahn taking the original line as written in the script ("[[spoiler: Yes. I did it. I killed Yvette. I hated her.]]") and adding onto it, with the knowledge of director Jonathan Lynn (and no one else). You can see Creator/TimCurry [[{{Corpsing}} trying not to laugh]], while [[EnforcedMethodActing Martin Mull and Christopher Lloyd are looking around wondering who gave her those lines]].
* VanillaEdition: The DVD and Blu-ray releases have no bonus features outside of the theatrical trailer. Jonathan Lynn was interested in recording a commentary for the Blu-ray, but Paramount Home Entertainment didn't have enough money for bonus features. [[Creator/KevinSmith A fan]] heard about this, and recorded a commentary for the film with Lynn and [[https://soundcloud.com/smodcast/377-clue-the-directors-commentary-track uploaded it to SoundCloud]].
* VindicatedByCable: HBO and broadcasts of this relatively inoffensive movie allowed ''Clue'' to stop being an OldShame for the cast and crew and become a cult hit, even with an AudienceParticipation midnight show, as detailed in a [[http://www.buzzfeed.com/adambvary/something-terrible-has-happened-here-the-crazy-story-of-how long article]] by Buzzfeed.
* WhatCouldHaveBeen:
** Creator/CarrieFisher was supposed to play Miss Scarlet, but she had to go to rehab a week before filming began.
** Director Jonathan Lynn wanted Creator/RowanAtkinson or Creator/JohnCleese to play Wadsworth, but [[ExecutiveMeddling the producers]] said that they weren't big enough names for American audiences. So instead he cast lifelong friend Creator/TimCurry.
** Creator/FMurrayAbraham turned down a role in order to star in ''Film/{{Amadeus}}''.
** A [[http://www.cluedofan.com/movie/movie_fourth_ending.htm fourth ending]] was filmed, but left out because it was less humorous than the rest. The events of the movie play out as usual, only at the climax, after reenacting all the murders, Wadsworth announces that Professor Plum is the killer. Plum objects, saying that he doesn't have the gun and leading to the "turn out your pockets, empty your purses" sequence. Wadworth produces the gun, explaining that in his lifelong quest for perfection, he has always failed: he tried to be the perfect husband, only to have his wife kill herself; he tried to be the perfect butler, only to find himself employed to a blackmailer. Therefore instead, he decided to commit the perfect murder by killing an entire blackmailing ring and leaving no witnesses. When the guests point out that ''they're'' witnesses, Wadsworth informs them that the brandy they were served at dinner was a slow-acting poison and that he plans to lock them in the house and leave them to die. The Jehovah's Witness returns and wrestles Wadsworth to the ground. Wadsworth confesses by beginning to reenact the murders ''again,'' while the FBI is too stunned to stop him. When he reaches the point where he greets Colonel Mustard, Wadsworth leaps outside, slams the door behind him, and locks it, trapping the others inside as he escapes in a police car. The Feds break through the Conservatory window (and presumably seek medical help for the poisoned guests). The film cuts to Wadsworth driving away, smirking at his success, only to hear growling from the backseat. He turns to see the guard dogs, who leap at him just before the film fades out.
*** There's actually a ''second'' fourth ending, originally written for the Novelization, that very closely resembles this one. Wadsworth was driven insane by the death of his wife and becomes obsessed with a need for purity and perfection. Upon learning about the immoral schemes of the six guests, he brought them all to the house, gave them all weapons, then invited their associates, knowing that the guests were so reprehensible that they would be unable to resist committing murder if they thought they could get away with it (in this ending even Mr. Green commits a murder). When each of the guests has killed their victim, Wadsworth then reveals that the brandy they were served at dinner was a slow-acting poison, which should be kicking in...oh, nowish. The guests drop dead. Wadsworth leaves by car, only to discover the guard dogs in the backseat. They attack him and he runs his car off the road. It is left unclear if the dog or the crash killed him.[[note]](though author Michael [=McDowell=] loved writing grotesque, bizarre deaths and "eaten alive by dogs" is well within his wheelhouse)[[/note]]
** There were plans to do an ending with each of the six characters being guilty of the murders, however it was scrapped when the studio and Jonathan Lynn felt it would be too hard to come up with an ending for each character, plus the twist of Wadsworth without seeming contrived and confusing, so only three endings, originally four, were made.
!!The board game
* MarketBasedTitle: "Clue" in North America, with Miss Scarlett losing a "T", Rev. Green being defrocked (or a businessman, which turns this into a PunnyName), and the distinguished Dr. Black given the pun name Mr. Boddy.
!!The British Game Show
* CastingGag: Mrs. White is played by Mollie Sugden in series 2. [[Series/AreYouBeingServed It's not the first time she's had to answer to someone named Peacock.]]
