* ActingForTwo: Creator/TimCurry, Richard O'Brien and Patricia Quinn can be seen at the wedding, though it's possible that these could be Frank and co. in disguise.
** In the play, Eddie and Dr Scott are always played by the same actor.
** The Usherette is usually played by the same actress as Magenta.
* BeamMeUpScotty: Funko had an online giveaway where they would give some of their Rocky Horror Funko Pop figurines to people who shared their favorite quote from the movie to them. A number of people had this (possible joke) response: "I'm Rocky Horror and this is my picture and this is the show during which I present my picture. Now let's dance and basically do sexy things."
* BigNameFan: The fan club's president, Sal Piro. He even [[PromotedFanboy has cameos]] in the [[Film/ShockTreatment sequel]] and [[Film/TheRockyHorrorPictureShowLetsDoTheTimeWarpAgain remake]].
* CaliforniaDoubling: Denton is implied to be in America but this movie was filmed in Berkshire, England.
** Some people will [[SpellMyNameWithAnS misspell Columbia's name as Colombia]]. Even the listing on the Funko website of Columbia's POP figure of Columbia website misspells her name, but the packaging calls her the correct name. In addition, the back of the packaging of the Funko Pops calls Frank N Furter "Frank N Further".
** Some people call Eddie "Meat Loaf", although that was his actor's name, not the character's name. Columbia also has a similar problem: occasionally, people call her "Little Nell" instead of Columbia, which is the nickname of her actress, Nell Campbell.
** Often, people will confuse Columbia and Magenta for each other. See the WhatCouldHaveBeen section for an ironic thing about this confusion between the characters.
** One RetroJunk article claimed that Columbia only showed up at the beginning of the movie and then returned at the end of the movie. This may have been because Columbia only has a few speaking lines in the film.
** The book TheCelluloidCloset claims that Frank N Furter [[spoiler:came back to life at the end of the movie. However, there have been several sequel ideas where that happens. Unfortunately, all those ideas have been in DevelopmentHell, and the first sequel with the resurrection concept turned into ''Film/ShockTreatment''.]]
** Some people believe that the Sweet song Ballroom Blitz was featured in this movie, and the people who think the song is in the movie might be confusing the song for The Time Warp.
** A few of the questions in the Rocky Horror trivia game, which was written by Sal Piro (who is the president of the Rocky Horror fan club), have incorrect answers.
** People will sometimes call the stage show "The Rocky Horror Picture Show" instead of "The Rocky Horror Show".
** A worksheet about blockbuster films claims that the movie came out in 1971. The stage show didn't come out until 1973, and the movie came out 2 years later.
** Some sources, including the Netflix description of the movie, claim that Frank N Furter is a vampire.[[note]]He isn't, but he's ''dressed'' as one when he descends in the elevator.[[/note]] JamesRolfe [[http://cinemassacre.com/2016/10/26/rocky-horror-picture-show-1975-monster-madness-x-26/ made the same error, as well.]]
** An article about Kelly Osborne dressing up as Magenta for her birthday claims that Magenta is Dr. Frank N Furter's sister. Magenta is actually the sister of Riff Raff.
** Creator/SusanSarandon refuses to talk about the movie, but not for the usual reasons. It's because she hates the fact that ''none'' of the cast members get royalties from the DVD sales.
** Creator/TimCurry was ''very'' reluctant to talk about the film for years and even told Creator/VH1 that he grew "chubby and plain" in order to try escaping the role. These days, he's more open to talk about the film and even sees it as a "Rite of passage" for teenagers. He even appeared in the 2016 remake as the Criminologist.
** Peter Hinwood (Rocky) is only slightly embarrassed by being in the film. Contrary to popular rumor, he's ''never'' thrown anyone out of his shop for talking about the film. He only sees the film as a "part of the past" and rarely talks about it.
** While happy with his performance in both the show and film, Music/MeatLoaf didn't like that he wasn't allowed to play both Eddie and Dr. Scott, as was customary in the stage production, and felt that Jonathan Adams (the Criminologist from the UK production) was horribly miscast, especially because he didn't have the singing voice for "Eddie's Teddy." He also didn't like that other movie musicals would try to type cast him, as he prefers to keep his music and acting career separate. To date, his only other singing role in a movie has been ''Film/TenaciousDInThePickOfDestiny'', filmed over ''thirty years later''.
* CutSong: "Once in a While," featured in the stageshow. For the film the song was to have been sung by Brad after his... erm... [[HoYay encounter]] with Frank. Footage was shot for it but left out of the film; a "reconstruction" using the footage and other bits from the movie has appeared as an extra feature on every home release of the film since the 1995 UsefulNotes/LaserDisc edition.
** To a lesser extent, the American print of the film had the exposition song "Super Heroes" all but cut out except for the final verse (the Criminologist's "And crawling..." speech). You can optionally restore it in the DVD release.
** To an even ''lesser'' extent, verses were removed from "Over at the Frankenstein Place" and "The Sword of Damocles." These were apparently never even shot.
* DevelopmentHell: Richard O'Brien has been mulling over making a direct sequel [[note]] ''Film/ShockTreatment'' doesn't count! [[/note]] to the original stage show for years. However, so far, all that's been seen are a few scrapped scripts and a vague concept that involves Frank coming back to life, though he's apparently written the first act to the sequel.
* DyeingForYourArt: In the original stage show, Creator/TimCurry dyed his hair peroxide blonde.
* EnforcedMethodActing: Several examples:
** Tim Curry was the only one who knew Eddie's corpse would be under the table. All of the reactions from the actors as he tears the tablecloth away are genuine.
** For the scene where Dr. Scott is dragged into the laboratory via electromagnet[[note]]GO, SPEED RACER, GO SPEED RACER, GO SPEED RACER, GOOOOO![[/note]], the production designers realized they forgot to build a door for him. What did they decide to do instead? Use him to knock down the friggin' wall.[[note]]HEY, KOOL-AID! OH YEAHHHHHH.[[/note]]
** During the dinner scene, Brad stamps his foot and Janet jumps at the table in shock; Barry Bostwick actually hit Susan Sarandon's hand with his fist during the take. Later on, she accidentally got even with him by stepping on his foot with a high heel during the floor show, which can be seen in the movie.
** Cols for Columbia.
** Crim for the Criminologist.
** Mags or sometimes also 'Mag' (pronounced Majj) for Magenta.
* FanCommunityNickname: Interestingly, only applies to a specific subset of the fandom: those who have never seen this movie in a theater with a live cast as part of the AudienceParticipation are referred to as "virgins" while those who've seen it regularly are called "sluts."
* HeyItsThatPlace: The exterior of Frank's castle[[note]]Oakley Court in Real Life.[[/note]] has been used in a few other horror films.
** ''[[Film/HammerHorror Hammer]]'' used it in; ''Film/TheBridesOfDracula'', ''The Reptile'', ''Film/ThePlagueOfTheZombies'', ''The Man In Black'' and ''The Lady Craved Excitement''
** ''And Now The Screaming Starts''
** ''[[Film/TheOldDarkHouse1963 The Old Dark House]] remake''
** ''Hound Of The Baskervilles''
** It was a hotel in the british TV show ''Series/PieInTheSky''.
* IAmNotSpock: Go watch any movie/show with Creator/TimCurry in it. Chances are, "[[EarWorm Sweet Transvestite]]" will start playing in your head.
* LateArrivalSpoiler: The music that plays during the main menu of the Blu-Ray for the movie is the reprise of Science Fiction Double Feature, where the lyrics describe the ending of the movie. There are also several fake movie posters that give away several of the plot points of the film. For instance, there is one poster entitled [[spoiler: They Came From Outer Space, which not only spoils the plot twist that Frank N Furter, Riff Raff, and Magenta are aliens, but the poster also shows a picture of Rocky carrying Frank N Furter's dead body in his arms.]]
* NoBudget: The film's budget was estimated at about $1,000,000, cheap even for the early 1970s, and it definitely shows.
** The lips singing "Science Fiction/Double Feature" are Patricia Quinn's (who played the usherette who sang it in the stage show), but they're lip-syncing to Richard O'Brian's vocals.
** Trevor White dubbed Peter Hinwood when it was discovered that Hinwood was completely incapable of singing.
* PropRecycling: The tank that Rocky first emerges from and the dummy that was meant to be him inside it were first used in ''[[Film/TheCurseOfFrankenstein The Revenge of Frankenstein]]''.
** The throne that Janet sits on in ''Film/ShockTreatment'' is Frank's after being upholstered red. The AmericanGothicCouple painting seen hanging in the dressing room is presumably the one from the first movie.
* RomanceOnTheSet: At the time Richard O'Brien was married to Kimi Wong who played one of the transylvanians.
* StuntDouble: According to the commentary;
** The motorcyclists at the start are stunt doubles with the Transylvanians hanging onto the back wearing their tuxedos under their motorcycle gear.
** Rocky and Frank during the KingKongClimb scene. When the Frank double realized he had to wear feminine lingerie, he started acting extra manly [[HaveIMentionedIAmHeterosexualToday so people wouldn't think he was gay]]. Richard O'Brien says he'd love to go back in time for half an hour and see this again.
* ThrowItIn: How the AudienceParticipation got started: one viewer during a screening shouted "Buy an umbrella, you cheap bitch!" during "Over At The Frankenstein Place" when Janet covers herself with a newspaper in the rain, and it just grew from there.
* TooSoon: One of the AudienceParticipation gags which evolves with the times: when Riff-Raff shows Brad and Janet the skeleton near the start of the film, it's customary to shout out "SHOW US" and the name of whatever celebrity has most recently died. Bonus points if it's someone people really liked, especially if they had an early or especially tragic death.
* UnintentionalPeriodPiece: Avoided for the most part thanks to its sheer strangeness. In fact, in quite a few ways the movie was ahead of its time: it looks more like an '80s film than a '70s film (accurately predicting the punk/New Wave hair and makeup styles, as well as the satiric Black Comedy brand of humor that characterized comedies during the Reagan era). What's more, the casual bisexuality and Frank N. Furter's schizoid mix of CampGay and HardGay behavior are still quite shocking today, at least if you don't consume such entertainments on a regular basis. However, the movie does anchor itself in the mid-1970s early on by playing a radio broadcast of President UsefulNotes/RichardNixon's 1974 resignation speech.
* VocalEvolution: In the original stage shows, Tim Curry originally played Frank with a German accent. He quit after a few shows, as he decided it was easier to just use his normal accent. Also, compare [[https://www.youtube.com/watch?v=qcb41SZO_Ys the original stage version of "Time Warp"]] to [[https://www.youtube.com/watch?v=ZanHo6Wn1H4 the more well-known film version]]. Can you believe that's Richard O'Brien and Patricia Quinn in both versions?
** Before Jim Sharman decided to use most of the original West End cast, ''Music/MickJagger'' auditioned for the part of Frank.
** Sharman's first pick for Brad Majors was [=Cliff DeYoung=], as he'd starred in his production ''Trials of Oz''. When Barry Bostwick was unable to play Majors in ''Film/ShockTreatment'', [=DeYoung=] was tabbed to play Brad by Sharman.
** Creator/SteveMartin auditioned for the part of Brad. Oddly enough, he'd go on to play a character similar to Eddie in [[Film/LittleShopOfHorrors another rock 'n roll musical movie]].
** '''Creator/VincentPrice''' auditioned for the part of The Criminologist.
** According to Meat Loaf, Music/ElvisPresley was the studio's first choice to play Eddie in the film version, and apparently Elvis actually had expressed some interest in doing so.
** According to the DVD commentary, Columbia and Magenta were originally going to be one character instead of 2 separate characters.
** Richard O'Brien has also stated that when writing the stage play, he actually envisioned himself playing Eddie, but the director hired for the play felt he would be a better fit for Riff Raff.
** Ever wonder why the opening song is just a pair of floating lips against a black void? It's because clips from all the movies mentioned in the song were going to be superimposed over. This was dropped when the producers realized that it would've cost a fortune in royalties.
** In an extended ShoutOut to ''Film/TheWizardOfOz'', the first third of the film was to be in black and white, switching over to color upon Frank's first appearance. His ruby red lips (see what they did there?) were to be the first thing to appear in color. This was cut for budget constraints.
** Patricia Quinn almost backed out of the film when she learned that she wouldn't be singing "Science Fiction/Double Feature," but changed her mind when she saw the sets and costume sketches. She eventually compromised by playing the disembodied lips in the opening, lip-syncing to Richard O'Brian's vocals.
** The unmade sequel ''Rocky Horror Shows His Heels'' would have said that Brad and Doctor Scott turned gay after the events of the first movie.
** ''Script/RevengeOfTheOldQueen'' implies it happened to Brad -- he left Janet and became a bottomless go-go dancer in Las Vegas.
** According to Richard O'Brien, it was actually Riff Raff who did most of the work on Rocky. Riff's line "Everything is in readiness, master. We merely await your... word". is pretty clearly a stab at Dr. Furter.
** O'Brien also explained that Brad and Janet are listening to Nixon's resignation speech three months after it occurred in real life because Brad taped it so he could listen to it whenever he wanted. He's just ''that much'' of a nerd.
** Creator/TimCurry has stated that Frank is actually "pansexual."
** [[http://www.rockyhorrorshow.net/story.htm The website]] for Seth Kubersky's production of ''The Rocky Horror Show'' goes more into Frank and the Transylvanians' backstory, saying they were a race of [[ImmortalProcreationClause immortals who'd lost the ability to breed]] and were trying to relearn how to from humans.
** The 2008 European live tour had Riff Raff and Magenta reappear toward the end as [[StarfishAliens twelve-foot-tall monstrosities with human upper bodies mounted on long robes concealing God-only-knew what]], thus making their (and Frank's) human appearances throughout the rest of the show nothing more than AFormYouAreComfortableWith.
** Darren Lynn Bousman has said on his Formspring account that the Graverobber from his movie, ''Film/RepoTheGeneticOpera'' is Riff Raff's son.
** Patricia Quinn has said in the commentary that Magenta and Riff Raff's relationship is completely innocent, and that the BrotherSisterIncest is all in the minds of perverted fans. (Richard O'Brien, on the other hand, was fully aware of the incestuous vibes. In fact, their analogues in the not-sequel ''Film/ShockTreatment'', once again brother and sister, actually ''are'' sexually attracted to each other.)
* WrittenByCastMember: Was written by Richard O'Brien who played Riff Raff.
