* BillingDisplacement: While a main character, Creator/AngelinaJolie's name didn't appear on the cover until after she'd become famous from other roles. She is, however, a prominent character.
* BoxOfficeBomb: Budget, $20 million. Box office, $7,563,728. It was panned by critics ''at the time'' for its dumb plot and its unconvincing portrayal of hackers. It still became a CultClassic.
* DawsonCasting: Although they were all playing high school students, Creator/JonnyLeeMiller was 23 at the time of filming, Creator/AngelinaJolie was 20 and Creator/MatthewLillard was 25. Only Jesse Bradford really fit the bill, being 16 at the time.
* FakeAmerican: Creator/JonnyLeeMiller as Dade.
* RomanceOnTheSet: Leads Creator/JonnyLeeMiller and Creator/AngelinaJolie got married after the movie's release, but divorced a few years later.
* TechnologyMarchesOn: The film is rooted in mid '90s technology:
** The characters are in ''awe'' of somebody's new, super-fast ''28.8b modem''.
** The main characters talking very highly of the RISC architecture (which is commonly used today in smartphones and tablets, but before those it'd faded into insignificance from a consumer point of view for about a decade and a half)
** The "battle of the tapes" scene — nowadays tape is pretty much unknown and they'd be fighting over digital files.
** Crashing 1,507 computers in a day is no longer that impressive.
*** Dade did that ten years earlier. ''In TheEighties''. And he hit the market so hard the NYSE dropped four points across the board. Nowadays he'd be in Gitmo until his hair fell out. Or [[MyGreatestSecondChance working for the NSA, FBI,]] or some other [[TheMenInBlack special government agency]], using his powers [[TheyFightCrime with other collared hackers to fight cyber-criminals]].
*** The NSA offers a scholarship program at MIT for students who will pursue a career with the agency. As he committed these hacks as a child, he'd probably be shortlisted for that program or something similar.
* UnintentionalPeriodPiece: This film (albeit with some unrealism that itself is a product of movie writers not really understanding what it is they're trying to tell a story about) portrays hackers at a time when they ''were'' a subculture, not well-understood by the broader populace as computers were not yet as ubiquitous as they are today (the Internet as we know it today was in its infancy, as well). As such, things like the importance placed on the "Hacker Manifesto", as an example, are products of the era when hackers felt themselves to be set apart from broader society in echoes of the 'generation gap' of the 1960s:
-->"We exist without skin color, without nationality, without religious bias... and you call us criminals. You build atomic bombs, you wage wars, you murder, cheat, and lie to us and try to make us believe it's for our own good, yet we're the criminals."
** Creator/HeatherGraham, Creator/HilarySwank and Creator/LivTyler auditioned for Kate.
** Creator/EdwardNorton auditioned for a role.
