The Exorcist
BBC America, 8:00 p.m. ET
Next year, this still-horrifying movie, made decades before the advent of CGI, will be 40 years old. Hard to imagine – but so is the intensity of this film, which tells of the demonic possession of a sweet little girl, played by Linda Blair. She’s seen at left in her “before” picture. Usually, when anyone discusses this movie, all you see is the “after.”
