Foreign horror films (depending on where you live)
They push the envelope much farther than American horror films.

I have a list of about 50 films considered to be the most gruesome films to date. I haven't watched all of them yet, but they are in my Netflix que...I don't know if they're scary, just gory and hard to stomach. Some of the ones I've seen I'll truly never forget.


When The Ring first released it scared the crap out of me. I can watch it now and be fine. But I remember going home and not being able to sleep without the light on. So did my mom's 50-year-old co-worker.
But it was one of those films where the theatre made it scarier. You could watch it at home and be fine.
The Grudge gave my dad night terrors.

But I'd recommend Old Boy directed by Chan-wook Park and Audition by Takashi Miike - anything by him in fact.

Silent Hill really scared the crap out of me because its a real place, its a really scarry place and it made me think... It wasn't just scare to frighten... It really stuck with me and made me question things.

ju-on the grudge the japanese original its super creepy the pace of the film changes throughout building fear and tension all the way very unnerving to watch.

It would depend on the mood your in at the time,being a nurse you probably see a few blood and guts from time to time,so maybe it would have to be something along the lines of "A Clockwork Orange" (circa 1970's)or "Faces of Death"(many different episodes)IDK,I like 'em too:)

like i commented before... the directors cut version of the exorcist on VHS... please do this...

also "the ring" very creepy... not one of the real good ones but very creepy... my dads weekness is dolls. like chucky, there is a black n white move with a bunch of little doll/puppets come to life and do crazy shit, that movie was wack

I haven't been scared by a movie for years, it was called The Changeling, there was a ghost of a drowned child and the thumping in the bathtub would go throughout the entire house, when I was little it scared the shit out of me.

The best scares I've had have all come from video-games, Silent Hill is great for scares because it doesn't do all that "this has big jaggy teeth, therefore is scary" crap, it's totally psychological, you're scared of what's not there rather than what is, what you can't see, great stuff.

F.E.A.R. and Condemned offer some classic scares as well, play with headphones, low lighting, and you will be scared, I guarantee, games are scarier because you're involved, not Resident Evil though, that's good but not even slightly scary.

It really depends on your tastes. When you say shake you to your core. Do you mean something violent, psychological, emotional, or just creepy.

I'm with you, I have never seen a movie that "scared" me, only a few that "creeped" me out a bit. Off the top of my head, the first I can think of is "The Thing" it's creepy and really bloody! Great movie! +4

For me, The Exorcist

My two favorite horror films are Cat People and American Werewolf in London.

The Others is also pretty good.
