The seventies were a decade of groundbreaking horror films: The Exorcist, Carrie, and Halloween were three. This detailed filmography covers these and 225 more. Section One provides an introduction and a brief history of the decade.

Beginning with 1970 and proceeding chronologically by year of its release in the United States, Section Two offers an entry for each film. Each entry includes several categories of information: Critical Reception (sampling both '70s and later reviews), Cast and Credits, P.O.V., (quoting a person pertinent to that film's production), Synopsis (summarizing the film's story), Commentary (analyzing the film from Muir's perspective), Legacy (noting the rank of especially worthy '70s films in the horror pantheon of decades following).

Section Three contains a conclusion and these five appendices: horror film cliches of the 1970s, frequently appearing performers, memorable movie ads, recommended films that illustrate how 1970s horror films continue to impact the industry, and the 15 best genre films of the decade as chosen by Muir.
