Continuity mistake: When the neighbours' house is burned down near the end of the film, it is shown briefly three more times without any damage.
Continuity mistake: After Ellie turns off the TV, Church turns around to look at her twice.
Continuity mistake: When Victor's corpse is in the hospital, the position of the streaks of blood down the middle of his forehead next to the wound change between shots.
Revealing mistake: When Louis sets Gage's lifeless body on fire, it becomes apparent that it is a stunt dummy. The body resembles a small, pale mannequin with vague facial features and a wig.
Continuity mistake: When Louis enters his garage, he leans his rake against the wall. When Church the cat runs out, the angle of the rake is different.
Revealing mistake: When the mother gets into an accident after her tire blows, the ghost shows up. It is floating above her car. Notice the seam where the ghost is on the car. When the scene shakes slightly, the ghost shakes too indicating it was a poorly superimposed shot.
Other mistake: In the beginning of the scene where Gage is killed by the Orinco truck, the truck leaves the plant. The number on the trailer is marked T-80. In the scene, the truck rolls over in the accident. In later scenes where Rachel hitches a ride home with another Orinco truck, the number on the trailer is also marked T-80.
Continuity mistake: In the scene at the table where Jud admits he is to blame for what happened to Gage, Louis is talking to him and the scene cuts to a wide shot. As Louis is talking he is looking at Jud and has his mouth open. Cut, and his head is down and his mouth closed.
Chosen answer: Church's behavior had changed after being buried. He was now violent (and working with Gage) and needed to be put down before killing anyone.
