Ditto, the best haunted house film ever made!

Also I like to add Onibaba (for that freaking mask sequence near the end) & Les Diabolique....now, H.G. Cluzot made this outstanding chiller without using any background score & that amazingly creates a very eerie feeling & unsettling atmosphere from start to finish.

The atmosphere is many of these classics were enough to creep you out. Especially the silent movies....the makeup and the way people moved....very creepy....just look at this guy

Alexander Granach as Knock in Nosferatu (1922)

The Birds always gave me the creeps, even more than Psycho, which I still admit is a brilliant film.

Along the same lines as the lack of scoring in Les Diabolique, there's no real score in The Birds, but the electronic twitterings that Bernard Hermann put under the bird sounds when they attack, make it so much more disturbing from such a subtle thing.

What Ever Happened to Baby Jane?

another one that creeps me out



could be the lipstick

The Exorcist....when she levitates, head spin, the demon voice, the way her face looks.....I still can't watch it without covering my eyes....or ears

You do better than me, I still can't watch it after walking (running) out of the theater when I was 13!

Thank you, atmosphere was actually the word I was looking for and exactly what I'm talking about. And yeah, Nosferatu has it in spades.

I wonder what it must have been like for a person in 1922 seeing that for the first time.

Les Diaboliques
Eyes Without A Face
Vampyr
The Fall Of The House Of Usher (1929 version)
Cat People
Curse Of The Cat People
The Innocents
Nightmare Alley (more film noir than horror)
Night Of The Demon (1957)
Night Of The Eagle aka Burn Witch Burn

Nosferatu for me as well. I like silent films, they make you feel the movie, more acting involved I think. Still creeps me out the way he just stares at you.

I would say (The Fall of the) House of Usher (1960) and The Haunting (1963). Believe it or not, I watched those movies just a few months ago and they actually scared me. I didn't think movies from the 1960s could be scary, but,in my opinion, they actually were (don't get me wrong, there are plenty of great older movies, I just didn't think they could be scary).
