Non Sci-Fi Dystopian Movies? (1984 fan)

Whenever I look up "Dystopian movies" or whatever, it always has the same sci-fi stuff that follows the same plots like robots and AI taking over, or things are in a simulation, etc..

1984 was really interesting to me for it's themes of totalitarianism, hopelessness, war, etc. - so suggestions based on my interests would be great. Sorry I couldn't be less vague.
