I've been thinking about the "techno-thriller" subgenre. It's a very narrow band, admittedly, but kind of a fun one. By definition, it has to feature technology, but it can't be so advanced that it's clearly sci-fi. It's also more of a subgenre of espionage thrillers than of science fiction or fantasy-action, even though the tech involved usually needs to be cutting-edge, if not near-future, and therefore it edges very closely to sci-fi. It's hard to slide a piece of paper between the Cyberpunk and Technothriller genres, but I feel like we have to. The sensibilities are different. It's also a genre that started in, and perhaps works best in, books rather than movies, but since this is the movies thread, I'm going to focus on movies.
Is The Terminator a techno-thriller? The Matrix? Not in my opinion. Neither are Her or Ex Machina. I also don't think technology-run-amok stories are necessarily techno-thrillers. I don't know if I'd call The China Syndrome (1979) a techno-thriller, for instance (well, I suppose it would be a "proto-techno-thriller", as below, if it qualifies at all). Are there some 007 or Mission: Impossible films that could be counted as techno-thrillers? Yeah, probably. What about Michael Chrichton movies? Is Jurassic Park a techno-thriller? No espionage element, so I'd say no.
Recommendations:
Proto-techno-thrillers, because to my memory, they preceded the use of the term:
The Conversation (1974)
Three Days of the Condor (1975)
War Games (1983).
The Hunt for Red October (1990) - I think the 1984 novel on which this movie is based might have been the germination of the term "techno-thriller", even though it can be applied retroactively to things that are older than that.
Sneakers (1992)
Strange Days (1995) - Lacks the espionage element, but I can't decide it if qualifies anyway. Maybe. If a genre becomes too wide, too inclusive, it loses its utility to define things for us; otoh, if it's too narrow, it's not very useful, either.
Enemy of the State (1998)
Captain America: The Winter Soldier (2014) - I think this is the only superhero movie I'd put in the category.
Eagle Eye (2008) - This one edges superclose to cyberpunk, for me, because of its use of an A.I. However, because the A.I. never materializes in any kind of humanoid form, it's never interacted with directly. iirc, it operates purely through existing communication and surveillance systems and devices. This one comes close to being a William Gibson story rather than a Tom Clancy story, if you know what I mean, but I think it still qualifies as a techno-thriller.
Kimi (2022)
Someone reminded me of The Kingdom (2007) recently. I remember liking it, but I can't remember if it had enough of the technology aspect.
