The Exorcist, originally released in 1973, was re-released in 2000, with 11 minutes of extra footage that had been censored in the original release. It also featured a digitally enhanced version of the Oscar winning sound by Chris Newman.
The Exorcist begins with Father Merrin (Max Von Sydow) on an archaeological dig in Iraq. A series of unsettling and ominous incidents occur, culminating in the unearthing of a little statue of a demonic figure.
Meanwhile in Washington, DC, a successful actress Chris MacNeil (Ellen Burstyn) is filming her new move with director Burke Dennings (Jack MacGowran). At the same time, a young priest Damien Karras (Jason Miller) is fighting inner conflict as his faith in God dwindles each time he sees his ailing mother suffer.
Chris' house in the upscale Georgetown neighborhood begins to witness strange occurrences. Her daughter Regan shows signs of eccentric behavior and complains about depression and anxiety. Medical tests reveal nothing. She is taken to a psychiatrist but ends up attacking the psychiatrist during the session.
The story of The Exorcist picks up pace, as the paranormal incidents increase in frequency and intensity culminating in the death of Dennings, who supposedly commits suicide by throwing himself out of a window while visiting Chris at her house. His body is found dead by Lieutenant Kinderman (Lee J.Cobb) at the edge of the stairs outside the house with his head fully twisted around his shoulders. Later Regan attacks her mother and injures her. The doctors are unable to assess Regan's medical condition and reluctantly recommend an exorcism.
