1984 by George Orwell - Goodreads: 1984

Saturday Night Dead
Another film that balances on the edge of science fiction – perhaps explaining its relatively low placing on this list. It doesn’t have anything to do with quality: ‘Ghostbusters’ is one of the great Hollywood films of the ’80s, a razor-sharp comedy with thunderous apocalyptic overtones which caught the public imagination in 1984 and hasn’t been shaken off since. Rumours of a reboot emerge on an almost daily basis.

"Dean of American Science Fiction Authors" Robert Heinlein had achieved a record-setting level of "hard SF" realism in co-authoring the screenplay for (and acting as Technical Director for) George Pal's film "Destination: Moon", which was loosely based on Heinlein's young adult novel "Rocketship Galileo" (New York: Scribner's, 1947), his first, which is the earliest science fiction novel that I can remember reading.
