Ghost Story: The New House
NBC airs the pilot episode of the supernatural anthology series Ghost Story, produced by 1960s horror movie mogul William Castle and starring Sebastian Cabot. Jeanette Nolan and Sam Jaffe guest star in a script by Richard Matheson (Twilight Zone, The Omega Man). The pilot gets enough attention for production to be greenlit on a series to premiere in the fall of 1972. (This series will be retitled Circle Of Fear in 1973.)
