!!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 is less humorous than the others. In this one, Wadsworth killed ''all'' the victims due to his disgust at their behavior and a sick need for perfection, and reveals that he has poisoned the other characters as well. The FBI shows up, and Wadsworth confesses by beginning to reenact the plot again. When he gets to the part where he answers the door for Colonel Mustard, he flees. Wadsworth attempts to get away in a police vehicle, but hears a doberman growling from the backseat, and is attacked.
** 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 Johnathan Lynn felt it would be too hard to come up with an ending for each character, plus the twist of Waddsworth 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.]]
