The whole scene in the woods in Deliverance (squeal like a pig). I had nightmares last time I watched that film.
The intro to the old Night Gallery series freaked me out crazy as a kid. Now the intro to Tales from the Darkside freaks me out as an adult, the music, ennui, and ambience of it just squiks me. I get the same thing from the classic Karen Black voodoo headhunter doll episode from trilogy of terror.
Oh hell yes. That was one of my top three worst movie moments ever.
Another would be the rape scene early in the Cape Fear remake from a few years ago. IIRC, DeNiro breaks one of the girl’s arms and takes bites out of her face while he is brutally raping her.
I was so skeeved I turned it off and never watched the rest, ever. I have never done that with a movie, before or since.
The scene at the end of Don’t Look Now. I get goosebumps thinking about it. They showed it on a clip-show the other day and it was horrible even then.
In Casino, where they put the guy’s head in a vise.
But the worst, worst ever, was the scene mentioned above in Ringu. It’s been spoiled now by imitation, and people vaguely know that it’s coming up, and the Hollywood version screwed it up a bit more too - but when I watched Ringu for the first time, I had no preconception or idea what the film was about at all, other than it was “a horror movie” - my friend just lent me the DVD and said “you have GOT to watch this”.
I am not ashamed to say that I screamed aloud.
I agree - our recollections of this scene are exactly the same and I was very disturbed as well
I remember that. It was awful. De Niro really frightens me in that movie. The original is supposed to be classic, but it never inspired the same fear as he did. Brutal scene.
Oh, and I can’t believe I forgot the chicken-eating scene in Poltergeist.
Were you guys watching Bravo’s 100 Scariest Movie Moments last night? It mentioned a lot of the shows you’ve named here.
Funny thing is, from just watching clip after clip of scary scenes last night, most of them weren’t actually scary without the buildup that precedes them. Only the clips that represented actual human behavior (Manson-style murders) were disturbing to me. And I’m a total wuss re: horror films.
My vote for freakiest movie is Jacob’s Ladder*.
When I was much younger and saw Carrie for the first time, the scene at the end with Carrie’s hand reaching up out of the rubble to grab Sue’s arm absolutely scared the crap out of me.
RoboCop (yes, RoboCop) That was before I’d been introduced to Verhoven’s over the top gore.
And the end of Aliens. I was home, alone, watching it in the dark, calming down after the climax, and my cat jumped up on my lap at JUST the right (wrong?) moment.
No mention of the chest-busting scene from Alien?
The scene in the most recent “The Thing” when the M.D.'s arms go into the victim’s chest and are chopped off. Really freaked me out. (the post above reminded me of that scary scene.)
The scene in “The Mummy” when the guy’s spectacles are stepped on and he can’t see… and the Mummy is coming. I watched it last night and it scared me again.
The feces in the kitchen scene in “Trainspotting”. That was my gaggiest moment.
Couple of movies come to mind for me.
Pretty much all of “se7en”, but especially the Lust Scene.
The end of “The Cook, the Thief, His Wife, and Her Lover”.
And a very old B/W movie I saw when I was a kid that I think was called “The Cage”. I still get creeped out when I think about the end where the antagonist gets his head squished by a car.
In Pet Sematary, the scene where Rachel (as an adult) sees her sister, Zelda.
The **Saving Private Ryan ** scene which someone has already mentioned. where Mellish(?) is slowly knifed by the German.
I absolutely love the movie as a whole, but I always squirm at that scene as poor Mellish is realising he is in big trouble and starts gasping “No, No” :eek:
Well mine tops them all for sheer terror.
The eponymous hero of the movie falls from an almost astronomically high place. As he plummets to earth with his trunk curled around a feather, Dumbo remembers the exhortations of his friend to believe, flaps his ears and flies!!!.
But it was real scary for awhile.

Actually I was going to cite the shower scene in Psycho, but it is totally bland compared to all the posts here.
I have never seen any of the movies in this thread, and for that I have no regrets. But I do apologize for the levity. Sort of.
This is going to sound really silly compared to some mentioned. But, 1) I was 5 at the time, and 2) my mom collected antique furniture that she kept in the basement.
In Psycho, where Vera Miles is in the basement and she sees the old lady sitting in a chair from the back. She slowly reaches out and turns her around and it’s the skeletal remains of Norman’s mom.
We had the exact same chair!!!
As others have mentioned, most of Se7en. I saw it listed in the cable guide a few weeks ago and had an involuntary shudder.
I don’t know why this creeps me out, but in Blue Velvet, where the detective gets shot in the head and remains standing, really bothered me.
Henry, Portrait of a Serial Killer - the scene where the family is tortured and killed and we watch it through a stationary video camera the killers had set up.
Funny Games - at the end where the two killers are on the boat cruising to their next house and as they are discussing comic books they casually, and without much thought, knock the bound and gagged housewife into the lake.
I love a lot of the suggestions here, but I’ve got an unconventional one from a movie that isn’t a horror, actioner, or thriller. Laugh at me if you want, but I can’t think of any memory more frightening than when I was a 5-year-old watching Pee Wee’s Big Adventure about four or five feet from a large screen when Large Marge decided to tell her truck wreck story. I had no idea what was about to happen. My parents were nearby on the couch watching too. I got up silently, perhaps in shock, and went and sat down next to them without even saying a word. I think I even put my arms around my dad for protection. I wanted to be as far away as possible from that screen for the rest of the movie. The fact that I was so close to the television multiplied the shock tenfold.
I still love the movie to this day, but I would close my eyes or look away any time I watched that scene until I was at least in my teens. 
I’ll third the Ring - the bit where Samara comes out of the TV scared the shit out of me.
