I really love the 70s idea of the future look. These are totally different types of sci fi movies, more hard sci fi fictionalized just barely ahead of contemporary technology, the plots are a bit less hard sf but both are super fun and are super focused on buttom and dial tech. Andromeda Strain and Phase IV. Andromeda Strain is based on a Micheal Creighton book from 1969 about and asteroid carrying a space disease and how Science People handle it in a state of the art containment bunker lab. Phase IV is about what if for spme reason all the ants in one region really got their shit together and made a coordinated attack taking out a small town which then turns into a mutual siege between the ants and the scientists who came to investigate, it sounds really silly but it is a genuinely good movie that takes the idea dead serious. Both have 5 minutes into the future tech but from the mind of the early 70s.

I really love the type of 2001 inspired sci fi movies that Star Wars killed, but I also count the first Star Wars as one of those movies, it has one foot in that pond still. Which is why its my favorite Star Wars movie. It dirties up the click click machines and dials but those were there before. Just usually in more austere settings. THX 1138 is a good example as well.
