Corrected entry: The blood splatter strains in Arnold's illusion of his wife and daughter's death are wrong. When a body is shot, the blood comes out in aerosol form from the exit wound. The stains on the wall look like they were squirted with a ketchup bottle.
Corrected entry: After Arnold drops through the newspaper stand from the helicopter and chases after the priest, we never really get to see him disconnect his harness. As a matter of fact he takes off running with it still attached.
Corrected entry: In the beginning of the movie, the camera is supposed to be giving us the view through Satan's eyes. We see the camera wind through a crowd of pedestrians, (pay attention this happens real quick) and we can see one man almost walk towards the centre then back up a step as if he almost ran into something. Keep in mind that no one is supposed to see Satan at this point.
Corrected entry: When Arnie goes on to the church for the first time, the priest dismisses him and exits through a door. When the door is open you see an ornate banner on the other side in a well lit room. When Arnie walks through the door it is into a small dark room at the top of some steps with no banner.
Corrected entry: In the first scene that we meet Arnold (when Kevin Pollack meets him in his apartment), Arnold starts throwing all kinds of stuff into his blender for breakfast (an obvious ripoff of "Men at Work"); the blender is filled to the absolute top, but then is a good 3-4 inches from the top of the container when he puts the lid on.
Corrected entry: In the scene near the beginning where Arnie is guarding the executive, we see a convoy of vehicles. The vehicle which Arnie is travelling in is a Chevrolet Suburban in the wide angle shot, but in the close frame shot where he actually gets out, the van is a GMC.
Corrected entry: In the end of the movie, in the church scene, the "wind of evil" blows down all the benches like dominoes. In the next second, they're all back in an upright position again.
Corrected entry: After Arnie has saved Christine from the priests who tried to kill her in her bedroom, he says "I've never heard the last rites performed before". However, a) he was not in the room when they were actually reading them, so he would not have heard above all the fighting, and b) it is unlikely that somebody who was not religious would recognise a ritual such as the last rites.
Corrected entry: In the scene after the priest writes down the number 666 (999), he says that the devil should "reproduce" at the last hour of the millennium. Arnold asks, "eastern time?", and the priest replies, that it's the position of stars that matters. However, at the end of the film the devil went down under because it couldn't "reproduce" at the last eastern hour of the millennium.
