I like the Hammer studio productions of Dracula with Christopher Lee. There were so many.
Here are some...
Dracula: Prince of Darkness (1966)
Taste the Blood of Dracula (1970)
Scars of Dracula (1970)
Dracula (1958)
I also like some more recent Japanese horror films such as THE RING and THE GRUDGE. I liked THE MUMMY and it's sequal with Brendan Fraser. Some Vincent Price films were entertaining such as THEATER OF BLOOD.
ROSEMARY'S BABY would be my favorite on that list we could select from.
I don't go to the theater much to see scary films, but I did enjoy THE SKELEON KEY. Even liked it better when I saw it again on DVD. I also enjoyed THE OTHERS.
