When a father returns from Chinatown with an unusual pet for his son, the rules are simple: keep it away from water, bright lights, and, most importantly, never feed it after midnight. But the rules are inadvertently broken, and the consequences multiply at an alarming rate.

William Friedkin directs one of the most horrifying movies ever made. When a charming 12-year-old girl takes on the characteristics and voices of others, doctors say there is nothing they can do. As people begin to die, the girl's mother realizes her daughter has been possessed by the devil—and that her daughter's only possible hope lies with two priests and the ancient rite of demonic exorcism. THE EXCORCIST: EXTENDED DIRECTOR'S CUT includes 11 minutes of scenes that are terrifying beyond words.
