I'm an old guy so which House on Haunted Hill are you referring to? I've seen them both but I'm partial to the older movie with Vincent Price. I saw it at the movie theater when I was young and had nightmares for a couple of weeks, Lee
I agree, for me The Exorcist was the scariest movie I've ever watched. I did a term paper in college of the national hysteria over that movie. People were flocking to Priests and psychiatrists convinced they were possessed after seeing the movie. I think the reason for me why it was so scary because it went beyond just a movie, I sensed as I'm sure millions of other people a real presence of evil. I came away convinced that there really is an evil force in the world. Lee
Another scary movie I haven't heard mention is Rosemary's Baby. That is an older movie but still good. I studied this film in a college class called the Psychology of Horror. Best class I ever took in college. All we did was critique horror movies. I only had to write one term oaoer and I received an " A" for the paper and the course...lol Lee
