Ever since the creation of silent movies, directors aim to shock the audience with explicit scenes of violence. Yet, little attention has been given to the evolution of horror movies. In order to create ‘monsters’, ‘dark locations’ and ‘explicit scenes of violence’ directors have to experiment with storylines and new techniques, if they want to shock the audience. The aim of this paper is to examine whether or not horror has become more violent (more extreme) throughout film history. Hence, we will discuss the historic evolution of horror movies in mainstream cinema (films that reached a large audience) and cult cinema (films which have a select, mostly fan based, audience).
