An interesting list from the Guardian of scariest films:
https://www.theguardian.com/film/2025/oct/31/halloween-scariest-movies-of-all-timeHmm..........really not sure about the films I do know on this list. "The Shining" is a very accomplished film, but, like many of Kubrick's films (to me, at least), it focuses more on style than substance. I loved the book, but when I saw the film, I felt very disappointed with it. I found the 1946 version of "Great Expectations" scarier, with the brilliant jump scare at the start of the film.
"The Thing" by Carpenter is good, but not by any stretch, for me a "scariest" film.
"The Innocents" I do like and would have on my list, along with the similar "The Haunting" (1963).
Another film I would put on the list is "The Mist", another King adaptation, which is so unrelentingly bleak and scary that I will never, ever watch it again. The ending was changed with King's approval to make it even more devastating.
As always, the problem with lists of this kind is the very individual nature of our response to horror films. What scares one person leaves another untouched.
So, what scared others so badly that they won't ever watch the film again?
