Spider Baby: or, the Maddest Story Ever Told is a 1967 American black comedy horror film, written and directed by Jack Hill. It stars Lon Chaney Jr. as Bruno, the chauffeur and caretaker of three orphaned siblings who suffer from "Merrye Syndrome", a genetic condition starting in early puberty that causes them to regress mentally, socially and physically. Jill Banner, Carol Ohmart, Quinn Redeker, Beverly Washburn, Sid Haig, Mary Mitchel, Karl Schanzer and Mantan Moreland also star. The film was released to relative obscurity, but eventually achieved cult status. Plot At the decaying Merrye House, feared by locals, the Merrye children Ralph, Virginia, and Elizabeth have lived in seclusion with the family chauffeur Bruno ever since their parents died. All three have advanced Merrye Syndrome, a genetic affliction unique to members of the family which causes them, starting in late childhood, to regress down the evolutionary ladder mentally and physically.

The children hold a steadfast respect and affection for Bruno, but increasingly disregard his admonitions against their darker impulses. Virginia's latest victim is a delivery man serving notice that Peter Howe and his sister Emily, distant relatives of the Merrye family, are coming with their lawyer Schlocker and his secretary Ann, seeking to claim the property as rightful heirs.

Schlocker is outraged that the children have been in the sole care of Bruno (who did not acquire legal guardianship) and have never attended school. Bruno tells him the children are mentally retarded and resists the suggestion to put them in an institution, having sworn to their father to protect them for life. Emily and Schlocker insist on staying overnight to examine the situation, but with only two rooms available, Peter takes Ann into town to stay at an inn. Schlocker investigates the house, going down
