Continuity: In the scene where Damien and his mother are at the zoo and are surrounded by baboons, they are in a small blue car. Suddenly, before they drive away, they are in a light colored station wagon.

Visible crew/equipment: When the ambassador and the photographer are in the cemetery getting attacked by the dogs there are men standing behind a tree. I'm assuming they're the trainers - they are located when the photographer is trying to hop the fence. Look in the back right hand corner - there are about two or three men standing there. (Time)

Audio problem: Near the end of the movie, when the Ambassador is dragging the child up the aisle of the church, in several spots you hear the child scream but his mouth isn't open. (Time)

Continuity: When Mrs. Baylock pushes Kathy from the hospital window, we hear the sound of breaking glass. However, when she plunges into the ambulance, there is no glass whatsoever, nor do we see any when she is falling. (Time)

Audio problem: When Thorn and Jennings are at the apartment in Italy they are talking about Bugenhagen and Jennings says that he is an exorcist and has read about him. However, his lips continue to move even after he has finished speaking. Although the camera is on Thorn and Jennings is blurred in the background, his facial movements are still easy to see.

Audio problem: When the baboons are attacking the car, Damien screams, but his mouth doesn't open.

Visible crew/equipment: When Peck is falling down the stairs with the kid, you can see the back pad through his coat.

Factual error: Jennings says that the name of Megiddo derives from Armageddon and that it is south of Jerusalem. In actual fact, Megiddo is the source of the word Armageddon, not the other way around, and it is a long way north of Jerusalem. (Time)

Factual error: It is highly unlikely that a British police detective making routine enquiries would be carrying a gun.
