Black Christmas 1974.
A crazed stalker slowly murders sisters at a sorritory house while police don't believe them until a police lieutenant takes charge after a girl is found dead in a park.
Bob Clark's psychological slasher horror that's still a classic packed with a dark atmospheric house and great acting from all involved Olivia Hussey, Margot Kidder, Kier Dullea and John Saxon. Do we really need a second remake of this film...i think not
