Are you a horror movie fan? I am. Love them. If I have the choice of movie to watch, I'll usually pick the scary movie first, before comedy or action. LONG before chick-flick.
Back in the old days Hammer was the big name in horror and made so many horror movies, essentially building careers for actors like Peter Cushing and Christopher Lee. They really paved the way for scary movies to become the huge product they've become.
