If you’re a fan of Joss Whedon’s Cabin in the Woods, it’s time to go back to the source and (re)acquaint yourself with the ultimate cult splatter movie. Sam Raimi’s instant classic, a textbook example of low-budget technical ingenuity and wildly inventive mayhem, is a laughing-screaming rollercoaster ride, balancing slapstick mayhem and over the top gore, once again underlining the kinship between horror and comedy. The recipe: Take six college students, a wood cabin, a forest, a copy of the Necronomicon Book of the Dead, a mysterious audio recording of a black magic incantation, an axe and a chainsaw…and don’t forget a sharp pencil. Mix with demonic possession and tree spirits, stand back and watch the fun. Contradicting the theory of “The Final Girl” as promulgated in Carol Clover’s estimable 1993 book Men, Women, and Chainsaws, Raimi offers for your delectation the ineffable Bruce Campbell as The Final Guy. (Trivia bonus: a young Joel Coen was an assistant editor on the film.)
