* BillingDisplacement: R&B star Music/{{Usher}} is [[CoversAlwaysLie featured prominently on the poster despite appearing in only five minutes of the movie]]. None of the other cast members were all that famous ([[RetroactiveRecognition at the time]]), while Usher is, well, Usher. This may have also leaned into DeletedRole territory, as some TV trailers for the film featured some additional footage of his character that was not present in the film's final cut.
* CompletelyDifferentTitle:
** ''Parasite'' (Japan)
** ''Dangerous Classrooms'' (Mexico/Argentina)
** ''A Lesson in Terror'' (Finland)
** ''Final Exam'' (Brazil)[[note]]''Film/FinalExam'' is known there as "Shadow Time"[[/note]]
** ''Mystery in College'' (Portugal)
** ''The Invasion'' (Greece)[[note]]Ironically, this would be the title of an ''official'' remake of ''Film/InvasionOfTheBodySnatchers'' nine years later.[[/note]]
** ''Them'' (Poland)[[note]]Not to be confused with [[Film/{{Them}} another sci-fi horror movie]] from 1954.[[/note]]
* DawsonCasting: Surprisingly little of it for a '90s teen horror film. The only twenty-something cast members playing teenagers were 22-year-olds Shawn Hatosy and Creator/LauraHarris and 21-year-old Clea [=DuVall=], all of whom were very close to the cutoff. Creator/ElijahWood, meanwhile, was 17 when he starred in this film, while Jordana Brewster was 18. Josh Hartnett was 20, but Zeke was repeating senior year, making him just a year or two younger than Hartnett (presuming this was the only time he'd been held back). [[spoiler: And Harris technically gets a free pass, seeing as she was actually the alien anyway.]]
* DuelingWorks: ''The Faculty'' was released on 25th December, 1998, six months after ''Film/DisturbingBehavior'', on 24th July, 1998. Both are quippy teen riffs on classic ParanoidThriller material: ''Literature/TheStepfordWives'' in the earlier movie's case, and ''Film/InvasionOfTheBodySnatchers'' in the later's case, both [[RecycledInSpace recycled in high school.]] Both have antagonistic adults, and both [[spoiler:rewrite their source material's ''very'' depressing endings so that the good guys win.]]
* DeletedRole: Kidada Jones filmed several scenes portraying a girl called Venus, who was advertised in TV previews and a tie-in Tommy Hilfiger commercial. Most of them were cut and she can only be seen in the science class scene, standing next to Gabe (Usher's character).
* FakeAmerican: The Canadian Laura Harris plays Marybeth, who claims to be from Atlanta and has a really thick Southern accent. [[spoiler: She drops it or at least dials it down once she's revealed as the alien queen.]]
* HeyItsThatPlace: Zeke's house is the same one from the film ''Multiplicity''. The driveway is cracked, referencing the opening of the film -- where the wrong driveway's concrete was broken up.
* IronyAsSheIsCast: Creator/CleaDuvall is a lesbian in real life. She portrays a straight girl who pretends to be gay to alienate people.
* MissingTrailerScene: Many shots and scenes in the trailer are not featured in the final product, including more footage of Coach Willis menacing someone. One website joked about this by showing a scene with the title "The Faculty, as not seen in ''The Faculty.''"
* ProductionPosse: It's a Creator/RobertRodriguez movie, so of course Creator/SalmaHayek is close behind. Rodriguez would also work with Creator/ElijahWood and Creator/JoshHartnett again in ''Film/SinCity''.
* QueerCharacterQueerActor: Subverted. While Clea [=DuVall=] would later come out as a lesbian, her character in this film is [[SorryImGay only pretending to be such to avoid attention]], and is actually straight.
* RealLifeRelative: The tattooed girl who points Marybeth in the direction of the principal's office is Robert Rodriguez's sister Tina.
* StuntCasting: R&B star Music/{{Usher}} in a small role as one of Stan's fellow football players.
* WhatCouldHaveBeen:
** Delilah was written for Creator/CharismaCarpenter. She turned it down, fearing it was too similar to [[Series/BuffyTheVampireSlayer Cordelia Chase]]. Speaking of which, Creator/SarahMichelleGellar turned down the role. Creator/JessicaAlba also auditioned.
** Creator/GillianAnderson turned down the role of Principal Valerie Drake. [[HilariousInHindsight Funnily enough]], if she had accepted, then Principal Drake and [[Creator/RobertPatrick Coach Willis]] would also have been [[Series/TheXFiles Agent Scully and Agent Doggett]].
** Creator/SherilynFenn was Rodriguez's first choice to play Elizabeth Burke.
** Kevin Williamson was going to direct as well, but he was busy with ''Film/TeachingMrsTingle'', so Creator/RobertRodriguez came on board too.
** The line "It must really blow being you" was originally said by Stan to Casey rather than the other way around.
** An earlier draft of the script has Elijah Woods’ character named as Pacey. If that name sounds familiar it’s because it belongs to Joshua Jackson’s character on Dawsons Creek, another creation by writer Kevin Williamson. Casey’s name was changed after the series premiered on television nearly a year before this film was released.
* WorkingTitle: ''The Feelers''.
