You are wrong. They most certainly do change society. I can give several examples. "China Syndrome" had a massive impact on the licensing for nuclear power reactors.
"Silence of the Lambs" is how we got the Homosexual censorship board on all subsequent movies.
"One flew over the Cuckoo's Nest" finished off what the book started, which was a complete flip on the national attitude regarding involuntary incarceration. This not only released all the homosexuals out of the asylums, it released all the other sorts of crazies into our society as well.
"To Kill A Mockingbird" was instrumental in passing the 24th Amendment and the Civil Rights act of 1964. Both of which have opened the door for massive abuse by the Federal Government.
"I was a fugitive from a chain gang" and "I don't want to die" softened the public's attitude towards both incarceration and the death penalty.
You have not a freakin clue. Movies (and books) do indeed change society. According to Abraham Lincoln, Harriet Beecher Stowe basically triggered the Civil War with her book "Uncle Tom's Cabin."
"The Jungle" caused massive upheaval in the Meatpacking industry and thereby created the Federal inspection system."
Not all movies or books have significant societal impact, but many do, and significant societal impact is often what their creators are attempting. Sometimes they succeed.
No they don’t. China Syndrome had no effect on nuclear power reactors, we’re twitchy about nuclear because A - we bombed Japan, and B - 3 Mile Island.
There aren’t homosexuals in Silence of the Lambs.
Geraldo Rivera’s report on Willowbrook is what flipped American attitudes regarding involuntary incarceration.
Dead activists lead to the CRA.
Oh look, there you go with the insults. Thus proving you know the facts don’t back you.
No movies don’t change society. Where was the big rise of Christianity after Passion? Lots of folks thought that movie would massively remake America, it sure did make money, but then it went away. Part of the problem is even the biggest hit movie is still really only seen by a small section of society. The new Star Wars is going to make hundreds of millions of dollars in its run and will be seen by less than 5% of the population. You don’t remake society on under 5%. Maybe a long time ago when we were a much smaller country with a much smaller entertainment industry and a much higher percentage of the population would consume the same thing. But if those days existed they passed over 100 years ago and will never come back. We are no longer a shared experience society.
