Mark Kermode revisits his 1998 cult documentary on The Exorcist.

In this exclusive extended version never seen before on TV, Kermode traces the extraordinary history of The Exorcist, the novel by William Peter Blatty that William Friedkin turned into a popular and controversial film. He examines the aura of mystery that still surrounds the film, the making of which claimed several lives. Alongside extracts and outtakes from the movie, there are interviews with Blatty, Friedkin, and actors Ellen Burstyn, Max von Sydow, Linda Blair and James Ferman, director of the British Board of Film Classification in 1998.

Introduction by Mark Kermode has been re-filmed from the 2019 version but is otherwise identical.
