The document summarizes the evolution of horror films from the 1950s through the 1980s. It describes how Hammer horror films of the 1950s-1960s focused on Gothic themes and atmosphere but declined as they became cliche. Horror films of the 1970s expanded into new genres like occult, supernatural, psychological, and nature/disaster films with higher production values and more graphic violence and gore. The 1980s saw the rise of slasher franchises like Friday the 13th along with more gore as budgets declined and films went straight to video.
