Roger Corman associate Jack Hill directly influenced The Texas Chain Saw Massacre with this taboo-obliterating horror-com about a family of cannibals who live in a dilapidated mansion and prey on passers-by.

Originally entitled Cannibal Orgy, Spider Baby boasts genre icons Lon Chaney Jr and Sid Haig but the real star is Ronald Stein’s jaunty Halloween score.

Chaney sings the title tune: “Cannibals, spiders, creep and crawl/ And boys and ghouls, having a ball!”

Argh! Wolfing dinner before a trussed-up guest.

Remake rights: Jeff Broadstreet (Dr. Rage) is tentatively pinned to a Jack Hill-produced redux, but it should be Mum & Dad’s Steven Sheil.
