> The technical details of the physical security systems are nonsense. Which parts are nonsense? The details of the "man trap" (including the voiceprint) are straight out of a late-80s Computer Security book I found at a garage sale last month: https://twitter.com/0x00C651E0/status/1521690225218490368/photo/1 https://twitter.com/0x00C651E0/status/1521690225218490368/ph... There's another section of the same book that describes ultrasonic motion detectors that work more or less like the ones in Cosmo's office. All of the other details I can think of offhand make me think the filmmakers did their research at least enough to get to the level of "it's plausible that someone would sell a security product that worked this way even if no one actually did in 1992", but I work in information security, not physical security. FWIW, I'm ordering Three Days of the Condor right now. Thanks for mentioning it.
