Societies fear as representations in film

 This is a fairly big subject firstly because fear is different for different countries in the U.K. there isn't a shared fear that a polar bear may maul us which may be the case for towns inside the arctic circle secondly because fear changes over time so representative examples from the 50s aren't likely to match ones from the 90s. Often it takes at least a little while for these fears to manifest in film because it usually needs some sort of catalyst or time for it to be worth showing it in film so that it shows as more than just an irrational fear 

This is Tetsuo: the iron man this is a Japanese film which represents fears in 1980-1990s Japan during this time Japan started to become a competitor in electronics bringing lots of money into the economy. The film follows the titular Tetsuo as he is cursed to become a being of Iron the fear of many in Japan in that time was that this technology would begin to trample over their rich history and culture. The film quite literally shows this a man is cursed(old culture) to turn into a metal man(new electronic business) symbolically saying if people keep on making electronics the spirits of the past will curse people to become what they make. 

the most horrifying examples of this would be films like The birth of a nation but an argument could also be made that their just a visual form of hate speech therefore they don't count instead of fear they are an amalgamation of hate which is a different thing. 

Dr. Strangelove is a satire but was filled with fears people actually had which was the government was full of idiots that powerful men in the 60s were womanisers anti Semitism was still a thing army generals are cowboys and everybody but the powerful was going to die a horrible fiery death. often Satire is a way to express fears about the current state especially politically which had a whole plot line about MPs in the houses of parliament voting against feeding children and guess what that happened in real life. Satire is one of the few places where you can look at your fears and laugh at them and maybe even discount them but the second they become real you know something must be wrong.

I was going to put a theory which has been shared around the internet here but i looked at the box office earning of the films mentioned it doesn't match up.

some take time and repeat

To kill a mockingbird 1962

watermelon man 1974

Mississippi burning 1989

glory 1990

remember the titans 2000

Lincoln 2012

Fruitvale station 2013

Selma 2014

straight outta Compton 2015

loving 2016

Detroit 2017

if beale street could talk 2018

queen and slim 2019

the banker 2020

Some of these films like glory and Detroit are set in the past but they are representative of problems which black people are struggling with in America especially now this could be done for alot of things like LGBTQ+ stories for instance or feminism.

even if regimes are in place films coming out of France in the 1940s often had to follow Nazi guidelines but hid messages or themes opposing the Nazis to wrap up because i smell and need a shower fear will always be represented in film whether through hidden themes, showing stories of the oppressed or satirically showing flaws in a political system and what disasters (nuclear war) may happen because of it (looking back it's more of a blog on social issues rather than fears but it's too late now)     People will always be able to get their anxieties and fears out through film. 

Simple thing at the end evil A.I. fear of approaching technological capabilities for example is a base way fear can be represented in films. anyways i found this...
