Hell Night (1981)-Starring Linda Blair as a sorority pledge who, along with three other pledges, have to spend the night in the "abandoned" Garth Manor. Of course pledges and members of the sorority and fraternity get killed one by one, so no surprises there. However, this film looks a lot better then most slasher movies although it may seem pretty tame. I love this movie and found it very entertaining.
976-EVIL is a 1988 horror film directed by Robert Englund. The film's title refers to the 976 telephone exchange, a now mostly defunct premium-rate telephone number system that was popular in the late 1980s, but has since been superseded by area code 900. http://en.wikipedia.org/wiki/976-EVIL
