1972 William Castle's Ghost Story Karen Black has a Bad Connection

Ghost Story is an American television horror anthology series that aired for one season on NBC from 1972 to 1973. Executive-produced by William Castle, Ghost Story featured supernatural entities such as ghosts, vampires, and witches. The show's format and tone drew comparisons to NBC's Night Gallery and ABC's The Sixth Sense. By mid-season, low ratings led to a title change to Circle of Fear and a change to the format.
