Other mistake: When George is in the basement, his son starts walking down the stairs. Suddenly a light bulb shatters right next to the boy's head, he screams, and falls violently down the stairs. But when it cuts to George coming over, he's just walking at a normal pace as though nothing happened. (This is just after they move in, before the evil spirits take hold of George, so there's no reason for him not to be alarmed.).

Directed by: Stuart Rosenberg
Starring: James Brolin, Rod Steiger, Margot Kidder, Don Stroud, Murray Hamilton
Continuity mistake: In the scene where the two priests are driving to the Lutz house and the car goes out of control, they alternate between shots of Rod Steiger and Don Stroud. The car's windows switch between closed and open in various shots. (00:42:00)
Father Delaney: God's peace in this house.
Trivia: When James Brolin was offered the role of George Lutz, he was informed that they didn't have a script to give him. James bought a copy of the novel and began to read it. At two o'clock in the morning, while reading a very intense part of the book, a pair of pants that he had hung up earlier fell to the ground causing him to jump in fright. After that, James agreed to do the film.
