@asekular - I love your first two choices of movies, particularly Brazil (the director's cut only - not Universal Studios fakakte disaster).
Even nowadays, where the audience is visually literate enough to realize most of the SFX of 2001 are matte overlays, the story is powerful enough to overcome that knowledge quickly.
Of course, the best "insider story" of the movie is Arthur C. Clarke telling of how Stanley Kubrick had 120 feet of 16mm film to "burn off" in his hand-held camera after a day shooting the "fight at the water hole" and he threw the bone in the air and shot it, repeatedly. He and Clarke had been arguing for weeks of how to get from the water hoie to a space station, and that night they were watching the "dailies" (all the film shot that day, developed and screened) and saw the bone, and they both realized at the same moment that they'd found the answer to their argument - the 2-million year "flash forward" in which the bone becomes a satellite (and one with the Chinese communist insignia on it to boot) - that footage in the film is Kubrick's 16mm "burn off".
Back in the mid-60s, when the two of them were starting to work on the movie, they wondered "what will the world be like in 2001?" Kubrick decided to ask scientists who were "on the cutting edge" of technological development what they foresaw. Among the scientists they contacted was my father. Among his 150 independent patents is the patent for determining if a pre-stressed concrete structure is solid, without breaking it open - which is why you have never ever worried about the freeway dissolving beneath your tires. It's a free patent that transformed the concrete construction industry, because he did it as a government employee. As he said "If I hadn't been working for the government, we'd be billionaires, but if I hadn't been working for the government, no one would have ever asked me the question that led to it."
Anyway, my dad, a lifelong s-f fan he (introduced me to the genre I ended up writing in when he gave me a copy of "Foundation" at age 10) was very happy to get asked "what will things be like in 2001?" And he always loved telling the joke on himself about what his answer was: "I told them that by 2001, solid-state electronics would be released to civilian use - something that happened two years after I told them that."
