* 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."
