When the film version of James Dickey’s 1970 novel Deliverance, directed by John Boorman, first appeared in 1972, it was perceived as a new kind of survival tale, one in which suburban men were confronted with the primeval forces of nature and completely traumatized by the experience. While it was mostly a character-driven adventure story, it had nightmarish elements that could easily classify it as a horror film yet it had a much broader appeal than a niche genre item. Nevertheless, some filmmakers took Dickey’s basic premise of some city folks venturing into unknown rural territory and turned it into a horror film template. Some of the more infamous titles are Wes Craven’s cult favorite The Hills Have Eyes (1977), Mother’s Day (1980), a sick black comedy from Troma Entertainment, Just Before Dawn (1981), directed by Jeff Lieberman (Squirm, Blue Sunshine) and The Final Terror (1983) featuring Daryl Hannah and Rachel Ward in early roles. My favorite though is the lesser known 1977 Canadian film Rituals (aka The Creeper), which comes close to generating the kind of white-knuckle tension that defined Deliverance while adding a number of gruesome horror tropes that make it consistently creepy and harrowing.
