Here's a few I though of...
Horror:
The Fog
Halloween
Friday the 13th
The Changeling. (Kinda slow but a really good ghost story with lots of goose bump moments)
The Evil Dead Series. (Good for Horror, some action and comedy.)
The Sixth Sense
John Carpenter?s The Thing. (Great horror movie, suspense and action)
An American Werewolf in London. (Horror with some comedy)
Psycho I & II (Sorry but I actually kinda liked second one.)
I found this list of someone?s idea of the top 100 horror movies that might help you.
