112	Below is a list of properties that were "unofficially" at the event, meaning that they were sneaked in by the event's creative team by using the CaptainErsatz method on casting sheets or building permits.
113
114	[[folder:Captain Ersatz Properties]]
115	* 1991: ''Film/TheExorcist'' (Regan tied to her bed was featured as part of some street entertainment)
116	* 1997: ''Film/TheExorcist'', ''Film/TheTexasChainsawMassacre'', ''Franchise/ANightmareOnElmStreet'', ''Franchise/FridayThe13th'', ''Film/{{Scream}}'', ''Film/{{Candyman}}'' (all appeared in the ''Universal's Museum of Horror'' house)
117	* 1998: ''Franchise/{{Halloween}}'', ''Film/TheTexasChainsawMassacre'', ''Franchise/ANightmareOnElmStreet'', ''Film/{{Scream}}'', ''Film/TheExorcist'', ''Film/{{Poltergeist\|1982}}'', ''Series/TheXFiles'', ''Film/TheShining'' (all appeared in the ''Museum of Horror'' house)
118	* 2003: ''Franchise/{{Halloween}}'', ''Franchise/FridayThe13th'', ''Franchise/ANightmareOnElmStreet'', ''Film/TheTexasChainsawMassacre'' (all four appeared in the ''All Nite Die-In'' house)
119	* 2004: ''[[Film/HouseOfWax1953 House of Wax]]'' (the ''Horror In Wax'' house was heavily inspired by the property)
120	* 2005: ''Series/BuffyTheVampireSlayer'' (the Body Collectors were modeled after "The Gentlemen" from the series), ''Franchise/{{Halloween}}'' (Michael Myers had a cameo in the ''Where Evil Hides'' house)
121	* 2006: ''Film/{{Scream}}'', ''Film/TheRing'', ''Franchise/{{Hellraiser}}'', ''Literature/TheSilenceOfTheLambs'' (all four appeared in the ''All Nite Die-In Take Two'' house)
122	* 2008: ''Film/EventHorizon'' (the ''Interstellar Terror'' house was heavily inspired by the property)
123	* 2009: ''Film/ArmyOfDarkness'' (featured in the ''Silver Screams'' house), ''Film/TheExorcist'', ''Film/{{Nosferatu}}'', ''Film/NightOfTheLivingDead1968'' (all three were featured in the ''Horrorwood Die-In'' scarezone)
124	* 2010: ''[[Literature/HellHouse The Legend of Hell House]]'' (the ''Legendary Truth: The Wyandot Estate'' house was heavily inspired by the property), ''Series/TalesFromTheCrypt'' (the Crypt Keeper was in the ''20 Years of Fear'' scare zone)

127	[[/folder]]
128
129	----
130
131	* BasedOnADream: The "Ring Around the Rosies" scene in 2019's ''Graveyard Games'' was based off of a nightmare that the event's former creative director, Mike Aiello, had once.
132	* CreativeDifferences:
133	** What caused the event's long-time Creative Director, J. Michael Roddy, to part after 2009.
134	** The reason behind the planned ''Film/Scream1996'' house being scrapped at the last minute in 2015. Long short story: the Weinsteins, who owned ''Film/{{Scream}}'' at the time, wanted the house to be based on the then-incumbent ''Series/ScreamTheTVSeries'', and Universal refused to budge.
135	* DawsonCasting: For obvious reasons, all of the child-aged characters in the event (such as Cindy) are portrayed by shorter adults. Usually the child characters are depicted as wearing masks in order to hide this.
136	* DevelopmentHell: Many of the event's houses go through this, as a house usually has to be proposed multiple times to get approved; something that can take several years. Another reason for this is that if it's a non-Universal IP house, then the creative team will need to get the blessings of the IP's copyright holder -- something that can also take a while. For example, an ''Series/AmericanHorrorStory'' house has been proposed ever since the show first started airing, but Universal wasn't able to convince Creator/{{FX\|Networks}} to let them have the license until 2016.
137	* DisabledCharacterDisabledActor: The event has featured several wheelchair-bound characters that are portrayed by scareactors that cannot walk and/or have no legs. There have also been a few cases of actors with deformities being hired to play up their unusual appearance.
138	* DistancedFromCurrentEvents:
139	** The reason why both Eddie and Cindy never came to be as icons. Universal was afraid Eddie would be considered too violent in light of the 9/11 attacks, so he was cut and Jack, a more fantasy-kind of villain, was brought back instead. With Cindy, she was cut due to child murders that had been happening around the area at the time.
140	** In the aftermath of the Pulse nightclub shooting in Orlando, Universal postponed the release of any new announcements concerning 2016's event until July. There were also plans to have a scarezone for ''Film/ThePurgeElectionYear'' at the Orlando event that year, but it was scrapped following the shooting.
141	** In 2017, the announcement of a house based on ''Film/TheShining'' was pushed back a few weeks following an Amber Alert of missing twin girls going around.
142	** During 2017's event, ''Bill & Ted's Excellent Halloween Adventure'' was originally themed around a pop-culture festival, and the plot of the show involved Bill and Ted having to prove to [[Film/BillAndTedsBogusJourney Death]] that there's something redeeming about pop culture, or else he'll drag all of humanity to hell. After the Las Vegas shooting, the show was given some major revisions, with the setting being changed from a festival to a concert, and Death looking to kill only Bill and Ted, not the entire world.
143	* DuelingWorks: In 2011, both Halloween Horror Nights and Theatre/HowlOScream had a haunted house based around Creator/EdgarAllanPoe, [[SimilarlyNamedWorks and both houses were even titled]] ''[[SimilarlyNamedWorks Nevermore]]''.
144	* DyeingForYourArt: Many scareactors and show actors have had to undergo physical changes for their characters, but the most extreme example may be for Orlando in 2010's ''Havoc: Dogs of War'' and its 2013 sequel ''Havoc: Derailed'', where every actor (male and female) shaved their head bald to play psycho super soldiers.
145	* ExecutiveMeddling: The event has experienced in some form since the beginning; and in particular, it's the reason why there has been an increase in IP houses over the past couple of years.
146	* ExecutiveVeto:
147	** During the event's earlier years, there were once plans to have scare actors inside the queue line for ''Ride/ETAdventure''. When Creator/StevenSpielberg found out about this, he immediately said no.
148	** When the 2002 event, Islands of Fear, was held in the Islands of Adventure part of Universal Orlando, Creator/DrSeuss' widow Audrey Geisel vetoed attempts to host a scarezone in the Seuss Landing area of the park, feeling that it would be a disgrace to Seuss' family-friendly work and threatening to end the Seuss estate's partnership with Universal if it did so. They ultimately settled on Boo-Ville, a (somewhat) LighterAndSofter Halloween area that did not have any scareactors, but still maintained the same kind of creepy music and unsettling atmosphere that the rest of the event has. The 2005 event didn't use Boo-Ville, but the North Hollow area they put there was still a safe zone without any scareactors, only dim lights and fog.
149	** Also during 2002's event, in a rather odd instance, one veto occurred after the event had already started. Supposedly, Universal did not give Creator/MarvelComics the full details on what they were going to do with the event's "Island Under Siege" scare zone and ''[[ComicBook/{{Carnage}} Maximum Carnage]]'' house. When Marvel found out about the event's depiction of the heroes being brutally killed by the villains and their bodies strung up as trophies, they were less than amused. Even before Marvel got bought out by Creator/{{Disney}}, this incident ensured that Marvel's characters would never appear in the event again, killing any hope of there ever being a house or scarezone centered around ''Comicbook/MarvelZombies''.
150	** Between the restrictions around using Seuss Landing and Marvel Super Hero Island, it's believed that this is why Universal moved the event back to the Studios park in 2006, as they had their hands tied with what they could put in two whole areas of Islands of Adventure.
151	** When the event returned to the Studios park in 2006, the ''Ride/{{Jaws}}'' skippers created their own script for the ride that was more adult and profane, which they hoped that they would be able to use during the event. However for reasons unknown, the script ended up getting shot down by the higher-ups.
152	* HeyItsThatPlace: [[https://www.youtube.com/watch?v=9UwjHk5tirA One of the commercials]] for the event in 2002 was filmed inside "Sting Alley", the hidden New York alleyway at Universal Studios Florida.
153	* MilestoneCelebration: Special anniversary years were done for the "Sweet 16" (2006), 20th (2010), 25th (2015) and 30th (2021) events. The "Sweet 16" event had the gimmick that every house was a sequel or prequel to one from a past event, while the other milestone events all had an anniversary house and scarezone themed on the legacies of Horror Nights' Icons and original properties.
154	* MissingEpisode: In a sense. Up until around 2001/2002 or so, the event was not widely documented by people, and several websites that did are no longer existent. Because of this, very few photos and videos of the event in its earlier years can be found, meaning that the only way to really get an understanding of what those years were like would be to listen to the stories of those who actually went back then.
155	* ProductionNickname: Every year, all of the event's houses are given vague, riddle-like codenames by the creative staff.
156	* PromotedFanboy: Many of the A&D members at Universal Studios in Orlando and Hollywood that helm the events started out as mere Scareactors/huge horror fans.
157	** One of the biggest strengths of John Murdy, the head of the Hollywood event and himself a Promoted Fanboy, is getting famous fans of the Hollywood event to become Promoted Fanboys and work on houses with him. This is how we got the houses for ''Film/{{Hostel}}'', ''Film/CrimsonPeak'', ''Film/ThisIsTheEnd'', ''Film/{{Krampus}}'', and many others.
158	** In addition to being involved in 2011's ''Film/{{Hostel}}'' house, Creator/EliRoth also designed the theme for the ''Terror Tram'' in 2016, and in 2017 directed the commercial for both Hollywood and Orlando's events.
159	** On a smaller scale, Latin pop singer Music/GloriaEstefan is [[JustForFun/OneOfUs a longtime fan of the Orlando event]], which she has attended every year since its inception. In 2012, [[http://www.bestoforlando.com/articles/Gloria%20Estefan%20Transforms%20into%20Vampire-scareactor-at-hhn-22/ they hired her as a scareactor for a day.]]
160	* PropRecycling: Very common, to the point of fans trying to identify what other houses and scarezones the props have been used in. Being Universal, they also get to use some movie props (such as a piece from ''Film/VanHelsing'' or a Triceratops head from ''Film/TheLostWorldJurassicPark''). Props from former attractions like ''Ride/{{Kongfrontation}}'' and ''Theatre/GhostbustersSpooktacular'' are even sometimes used.
161	* RecycledSet: The event has done this from time to time, one notable example being that 2010's ''Havoc: Dogs of War'' re-used many of the sets from ''The Spawning'' house from the year before it.
162	* ReleaseDateChange:
163	** The first night of Halloween Horror Nights 25 was originally planned to be on September 25th, and it was also going to last for 25 nights; but due to fan demand for more nights, this plan was scrapped and the event instead started earlier on September 18th, and ran for 30 nights.
164	** Due to the UsefulNotes/Covid19Pandemic, the 2020 event in Orlando and Hollywood was canceled out of safety concerns. What would have been the thirtieth year for the event was pushed to 2021.
165	* RoleReprise: For one night only at the Hollywood event, [[Creator/LupitaNyongO Lupita Nyong'o]] played her character, Red, from ''Film/{{Us}}'' in the house based on the respective film.
166	* ScrewedByTheLawyers:
167	** After 2006, ''Bill & Ted's Excellent Halloween Adventure'' became much more limited in what it can do with its parodies than in the past. For a long time, the show had absolute freedom in what it would lampoon, as the general assumption is that it falls under the "Parody" clause of Fair Use. Things changed in 2006, when Creator/{{Disney}} seemed to disagree and threatened to sue Universal over how the show that year utilized [[Franchise/PiratesOfTheCaribbean Jack Sparrow and Elizabeth Swann]]. The controversy only worsened when on that same year Creator/DCComics came down on Universal for its usage of [[Franchise/{{Superman}} Lex Luthor]] as the main villain of the show, and ultimately filed a cease-and-desist letter against them, which resulted in Lex Luthor being replaced by [[Film/AustinPowers Dr. Evil]] on the final night of the show. After that, the show avoided putting certain copyrighted characters in the spotlight for too long, instead doing things like using a celebrity as the show's main villain rather than a movie villain. This also led to them completely banning videotaping and photography of the show, so as to prevent it from getting onto the internet and attracting unwanted attention. It is believed that the rising worries concerning the potential of legal backlash over the show's content was one of the many reasons why the show was brought to an end after 2017.
168	** Disney's acquisition of 21st Century Fox in 2019 put the kibosh on any chance of ''American Horror Story'' and ''Alien vs. Predator'' returning to this event hosted by their theme park rival for that year and beyond.
169	* SequelGap:
170	** 2004's ''Hellgate Prison'' house, despite being a fan-favorite, would not get a sequel until 11 years later in 2015's ''RUN: Blood, Sweat, and Fears'', which is set inside the prison.
171	** Another house from 2004, ''Ghost Town'', went without a sequel for 12 years until 2016 with ''Ghost Town - The Curse of Lightning Gulch''.
172	** ''Film/ThePeopleUnderTheStairs'' was one of the houses in 1992 and 1993, with it not being until 13 years later that it got a sequel in 2006 called ''The People Under The Stairs: Under Construction''.
173	** ''Dead Exposure'', one of 2008's houses, didn't receive a follow-up house until its 10th anniversary in 2018.
174	** Though they appeared more frequently at Hollywood's event, Freddy, Jason, and Leatherface went absent from Orlando's event after their appearance in 2007's "Carnival of Carnage" for several years. Freddy and Jason eventually returned in 2015 with the ''Freddy vs. Jason'' house, while Leatherface returned the following year in a house based on the original ''[[Film/TheTexasChainSawMassacre1974 Texas Chain Saw Massacre]]'' film, rather than the 2003 remake.
175	** ''Franchise/{{Saw}}'' got houses at both Orlando and Hollywood in 2009. Hollywood got a sequel the next year, but then ''Saw'' disappeared from the event until 7 years later when ''Saw: The Games of Jigsaw'' was at both parks.
176	* SeriesHiatus: Universal Studios Hollywood's HHN has gone through this a total of ''three times''. It first started in 1986, but after an incident that resulted in the death of a scareactor, it was canceled until 1992. After 1992, it again went dark until 1997 and continued to run for 1998, 1999, and 2000 before once more going on hiatus. In 2006, the event was at last revived and has been run every year since.
177	* SleeperHit: When the Orlando event first began in 1991, management was not expecting it to be very successful and were unsure if they would be doing it again the next year. The event ended up being a huge success, with lines for that year's only house, ''Dungeon of Terror'', reaching over three hours long. Its success would then of course go on to make Horror Nights a yearly occurrence.
178	* ThrowItIn: Jack and Chance were fully allowed to improvise heavily in 2015's ''The Carnage Returns'' show, resulting in numerous [[ShoutOut Shout Outs]] and other random fun moments.
179	* TrollingCreator: John Murdy, a self-professed carny, does this during the leadup to Hollywood's events with various puzzles and hints to what the houses are based off of the code names. They are ''not'' easy to solve.
180	* ViralMarketing: Several of the event's years utilize this in advertising.
181	* WhatCouldHaveBeen: See [[WhatCouldHaveBeen/HalloweenHorrorNights here]].
182	* WorkingTitle:
183	** As said earlier, much of the houses, scarezones, and shows for 2001's event were altered following the 9/11 attacks.

194	** 2017's ''The Horrors of Blumhouse'' was initially titled ''Blumhouse of Horrors''.
195	* YouLookFamiliar: It's very common to see recurring scare actors throughout the event's years playing a different role. Even within the same year one scare actor can play multiple roles.
196	** [[http://www.imdb.com/name/nm1599810/?ref_=fn_al_nm_1 Erin Nicole Cline]], the main actress that portrays Chance, also played [[WesternAnimation/Frozen2013 Princess Anna]] in 2014's ''Bill & Ted's Excellent Halloween Adventure'' show as well as the "Ring Mistress" in the ''20 Penny Circus'' show from 2012.
