Crap! This is gonna take a while...
I'm doing this off the top of my dented haid so... I may miss a fiew.
Hammer Films:
All the Hammer Vampire movies from the 60's and 70s./
Misc:
"Salems Lot" - The original mini-series, scariest ever done.
"The Exorcist" - For obvious reasons.
"The Omen" - Second on to the above.
"The Fog" - John Carpenter at his best.
"The Ring" - Too effin scary for words.
"HellRaiser" - Sick, sick... sick!
"The Night Gallery" - Seasons one and two.
"The Howling" - Best werewolf movie ever made.
"Dog Soldiers" - Second best werewolf movie ever made.
That's about it, more into SciFi actually but I like a good chill every now and then.
