* CompleteMonster: [[FameThroughInfamy Matthew Grimes]], while still alive, was an attention-seeking political [[WesternTerrorists terrorist]], known for [[MadBomber bombing populated areas]]. Developing an obsession with police officer Parker Barnes, Grimes [[IHaveYourWife took his wife and daughter hostage]] in a kidnapping that killed them both before Parker shot him dead. Uploaded as one of the psychopathic personalities in the [[DigitalAbomination SID 6.7 program]], Grimes' influence causes SID to take a nightclub hostage, terrifying and killing patrons at his leisure, before aiming to climb higher and higher in infamy while taking every opportunity to continue tormenting Parker.
* SugarWiki/FunnyMoments:
** SID jumps into the UFC octagon and manages to freak out Wrestling/KenShamrock out of all people by showing him his disfigured hand while laughing.
** When SID hijacks a televised debate, he rips the nametag patch off the maintenance uniform he stole and replaces it with one with his own name, with no explanation as to how he got it.
* HilariousInHindsight:
** Sid standing in the middle of the Ultimate Fighting Championship ring with his arms raised above his head becomes a lot funnier when five years later Creator/RussellCrowe found himself in a similar scene in ''Film/{{Gladiator}}''. The only thing missing is Sid/Crowe yelling "Are You Not Entertained?!"
** During rooftop fight Parker keeps asking SID "where is the girl?" and years later [[Film/LAConfidential Crowe's character]] would do the same thing.
** Sid also reacts to some glass that heals him as "A good year", [[Film/AGoodYear a movie Crowe later starred in]].
** Russell Crowe and Creator/KevinJOConnor both later appeared in modern remakes of ''Film/TheMummy1932''. Connor, who plays Clyde, the poor bloke who gets his neck broken by Sid, would four years later after appearing in this movie play Beni Gabor in ''Film/TheMummy1999'', while Crowe, who plays Sid, would later appear in ''Film/TheMummy2017'' as Dr. Henry Jekyll and Mr. Edward Hyde (the latter of the infamous SplitPersonality MadDoctor from Creator/RobertLouisStevenson's [[Literature/TheStrangeCaseOfDrJekyllAndMrHyde book]] would share similarities with Sid from this film).
** Originally, Creator/RobertDowneyJr was supposed to play Sid until Russell Crowe replaces him, thirteen years later, Downey would later helm the Academy Award-nominated role of method actor Kirk Lazarus, which is said that Crowe was one of the inspirations behind him, in ''Film/TropicThunder''.
** Crowe and Washington would later star in ''Film/AmericanGangster'', only with Crowe as the hero and Washington playing the villain.
* HoYay: Lindenmayer ''really'' loves his masterpiece. Sid's able to hypnotize him easily, which makes sense considering his origins as a hippie cult leader, fascist orators, and more.
* MemeticMutation: Sidson [[labelnote:Explanation]]A Soyjak variant created by Creator/VinluvHandesbukia which was based on a frame of SID 6.7 with a strange expression.[[/labelnote]]
* {{Narm}}: The UFC audience is depicted as chanting "kapow!" to a beat, even after SID throws a man to his death, gets his fingers blown off by a shotgun, and later [[UnusuallyUninterestingSight leaps into the UFC octagon with superhuman ability]].
* MoralEventHorizon: Lindemeyer crosses it when he sends SID 6.7 to the real world, who then snaps Clyde's neck.
* RetroactiveRecognition:
** This isn't Creator/RussellCrowe's first American movie, but it is an early one. It is also the second acting job for a ''very'' young, at most 9-year-old, Creator/KaleyCuoco, who plays Karin Carter. Her first movie was ''[[https://en.wikipedia.org/wiki/Quicksand:_No_Escape Quicksand: No Escape]]'', from 1992.
** The film also has a scene take place at an Ultimate Fighting Championship fight, years before the company would gain mainstream prominence.
** [[Franchise/{{Saw}} Detective Mark Hoffman]] has a fatal run-in with Sid in the opening.
** "Matthew Grimes" is one of those actors who's been in everything, most notably as Dean Rivers in ''Series/{{Zoey 101}}'' (which happens to be owned by Creator/{{Paramount}} who distributes this movie).
* SpecialEffectFailure: The virtual reality scenes have not aged well since its release.
* SpiritualAdaptation:
** This film would be the closest thing to an ActionizedSequel to Creator/WesCraven's ''Film/{{Shocker}}'', as SID shared some traits with Horace Pinker and the last time Pinker was seen, he was trapped in the TV world and SID escaping from the VR world to commit serial killings in the real world felt like a transposal of Pinker escaping from the TV world to do the same thing.
** Due to the Film/DarkUniverse becoming a StillbornFranchise thanks to the poor reception of ''Film/TheMummy2017'', this film is retroactively the closest anyone would get to fill the void of seeing a spin-off that follows Creator/RussellCrowe's Dr. Henry Jekyll and Mr. Edward Hyde whom the latter shared similarities with SID not to mention Crowe's penchant for EvilIsHammy in those AxCrazy roles.
* UnintentionalPeriodPiece:
** The computer graphics used to create SID are very dated.
** SID wears a very baggy, double-breasted suit and round tea shades, all fashion trends that died in the 90s.
** Barnes needs to explain what an emoticon is. In the film, it's because they fell out of favor by 1999, but in the real world, it's because the filmmakers didn't trust everyone in the audience to know what they are.
*** This happens with most of the internet/computer references. Clearly the filmmakers largely expected internet culture to stagnate or even die out like a fad, as was a prevalent belief in the eighties and early nineties. There's zero effort to imagine it as having flourished and become ubiquitous.
** The film's version of the UFC is very inaccurate and sensationalized, obviously coming from the "dark age" of UsefulNotes/MixedMartialArts when the sport was considered an unsavory, underground spectacle and not widely understood.
** The oddly [[SoundtrackDissonance dissonant]] grunge rock song[[note]]"White Discussion" by Music/{{Live}}[[/note]] that plays when Barnes escapes from the prison truck.
