This late out of the blocks made-for-t.v. rip-off of "The Exorcist" is unlucky enough to 'star' James Farentino, busy nursing his two expressions until the next mini-series comes along. What redeems this film though are a strong performance by a young Harrison Ford and a simply terrific one by Joan Hackett.Her character oozes madness, repressed sexuality and fierce intelligence, displayed with a clarity reminiscent of Anthony Perkins work in "Psycho". Rarely has insanity been so chillingly portrayed as here, despite the limitations of the format.
