Black Christmas is without a doubt the greatest horror film you've probably never seen. I hadn't heard anything about it myself until I noticed it cropping up on a lot of people's favourite horror film lists, so decided it was about time I saw what all the fuss was about. The film centres around a Sorority house in the Christmas holiday season, where the girls begin receiving a series of disturbing phone calls from an unknown source. It soon becomes apparent that a faceless killer is stalking them, a killer who has snuck in through an open window and is inhabiting their attic... Pre-dating all of the classic horror films of the late 70s and 80s, Black Christmas is a stark, stylish and creepy film that boasts some chilling moments and some great performances. The genius of the film lies in it's ability to evoke an intense atmosphere of forboding which leaves you constantly unsettled and totally immersed which it does without the need for special effects, gore, or cheap scares. The direction, framing, POV shots, and lighting all work toegther seemlessly to provide moments that really leave you cold (especially the eye through the crack of the door). The script deserves a mention too, because it really is superb. There are some great characters, some good threads of drama and even comedy, but these are brilliantly and appropriately contained within their scenes without detracting from the menacing atmosphere and overall theme of the film. The phone calls are one of the high points, containing shades of Reagan's multi-voice outbursts in the Exorcist but with overtones of despair and confusion which give an insight into the psychological state of the deranged killer. All in all, if you are a fan of horror, and looking for something more than the slick disposable dime a dozen slasher films of recent years, you simply have to own this little gem.
