Event Horizon- space horror starring Sam Neill and Laurence Fishburne, very good for it's time and still holds up.
In The Mouth of Madness- another great Sam Neill epic.
The Omen movies ie the originals more than any new version and the trilogy or one of them concludes with Sam Neill also as the AntiChrist adult version of the character I believe.
Shadow of the Vampire starring Willem Dafoe was good.
Salem's Lot is another good horror movie ie the one I'm talking about I believe is from the 80's and still holds up at psychological horror rather than depending on over the top constant gore effects.
Silver Bullet starring Corey Haim and Garey Busey is an oldie but a goodie.
The Lost Boys starring Keifer Sutherland is good too but not super scary if thats what you're actually looking for.
