Novelist and filmmaker William Peter Blatty (left), a former Jesuit school valedictorian who conjured a tale of demonic possession and gave millions the fright of their lives with the best-selling novel and Oscar-winning movie "The Exorcist," died Thursday, Jan. 12, 2017. He was 89. 

He's shown here with Linda Blair, who starred in the 1973 film and William Friedkin, the film's director, at a screening of the remastered film at the Museum of Modern Art in New York.
