I’m surprised that 13 Monkeys isn’t in there.
Perhaps not in the dystopian genre but 3 movies that started out as novels which potentially could happen in reality
Atlas Shrugged-Ayn Rand
Transcendence - movie staring Johnny Depp about AI
Never Let Me Go - novel written by Kazuo Ishiguro that was turned into a movie
Is 13 Monkeys the sequal to 12 Monkeys?
Great movie as are many of Terry Gilliams. Brazil is also a good dystopian flick.
13 Monkeys was great
