Below is a list of movies that don't quite qualify as slasher films (at least, not in my mind). That does not mean, however, that they are not important to the genre. In many cases, the following films have either helped to create the genre or influence it over the years, and therefore they deserve to be mentioned on the site. Comments or suggestions? Send them to me.
Carrie (1976)
The Dentist (1996)
Halloween III: Season Of The Witch (1983)
Psycho (1960)
The Rage: Carrie 2 (1999)
