9. Black Christmas (1974)
Starring a pre-Lois Lane Margot Kidder, Black Christmas was a simple film about a sorority house closing up for Christmas. The only thing is that for the ones that are remaining they are continually harassed by anonymous phone calls and the occasional murder as the girls are picked off one by one. Over-shadowed perhaps by the released in the same year American-made Texas Chainsaw Massacre, Black Christmas nonetheless helped set off a storm of "stalker" films and helped to open the blood-gates to such later 70s and 80s films such as Driller Killer, Sorority House Massacre, April Fool's Day, Hallowe'en, Sleepaway Camp and the like. Black Christmas was director Bob Clark's coming out party and his long-time commitment to the easy Canadian film tax credit that would see Canada fund his greatest hit, Porky's whose success allowed him to make his pet project, the classic cult Christmas film, A Christmas Story. Bob Clark was unfortunately killed by a drunk driver in April 2007.
