Other mistake: Near the end of the movie Dwight Yoakam is holding Jodie Foster's daughter captive as he tries to exit the house. Jodie Foster sneaks up behind him with a sledgehammer and swings it at his head. He turns to face her and the metal end of the hammer catches him firmly in his temple, knocking him down a flight of stairs. A few minutes later he comes up the stairs and tackles Jodie Foster to the ground, seemingly unhurt by the impact of the sledgehammer.
Other mistake: Leo Crow grabs Anderton's gun and they each fight for control of it. Crow succeeds in forcing Anderton's hand to pull the trigger, killing Crow. The problem is, right after the gun is fired, we see a shot of Anderton with his arm fully extended and with his entire hand holding the entire gun, as if he had aimed and fired the gun himself. Such a sequence of events is at least totally illogical if not physically impossible. (01:44:10)
Other mistake: While downstairs Vernon hears Hedwig's squawks, as well as Dobby and Harry's exchange in the bedroom upstairs, distracting enough for them all, including the Masons, to take note. The noise upstairs illicits a reaction from everyone, which Vernon explains is a noisy cat. Yet when Harry very noisily chases Dobby down the steps, Dobby slams into the wall and Harry lands with a loud thud (not remotely 'catlike'), Vernon, who stands on the other side of the shared wall, pleasantly continues his story to his rapt guests, who are also not distracted by the noise. To suggest that such loud noises coming from the hallway right beside them would not draw any reaction from anyone, Vernon and the Masons included, is preposterous. (00:06:45)
Other mistake: John explains to his friend Ed that, within the last two weeks since the accident, Mary has undergone brain surgery to remove the tumor in her right temporal lobe and that she is undergoing chemotherapy. This surgery alone would necessitate shaving at least half of Mary's head, and the chemotherapy would prevent her hair from growing out again for months. But, in the immediate next scene, we see John at Mary's side as she recovers in the hospital, and her red hair with natural hairline is as full and lush as in the beginning of the film.
Other mistake: When Kelvin slices a cucumber he cuts his finger. The way he was attacking the cucumber he would have cut a piece of his finger off but not cut into it. The same happens again at the end of the movie. (00:03:30)
Other mistake: In the scene where Gwyneth Paltrow and Aaron Eckhart are talking about lesbian literature, the Geography of the University is all wrong. They start off walking down outside the Learning resource building (the library), and the next shot of of them travelling up an elevator, before exiting on the third floor of the library. But the elevator they travel in is actually located in the main University building, which is located opposite the library. I should know, I was at the University for six years.
Other mistake: After Jason rams the man through the railing at the top of the stairs, he puts in a new clip. As he falls through the air, he shoots the other guard once. Then, he puts in a new clip when he rises after the fall. After one shot?
Other mistake: When the gang is in the mystery machine and Scrappy pees on Daphne and they kick Scrappy out of the car, from a distance the driver isn't Fred - it is someone with dark hair, not blonde.
Other mistake: This occurs during the scene where the group has just rescued the colonel. Before Mrs. Paley makes her appearance, the others notice the panel opening, and make movements, but they don't make sense. We'll call the side where the colonel was the north. Sasha is in the southwest corner, and Max is near her. Simon and Jerry are both at the north wall. When the sound of the door opening is heard, Max looks to the west. Simon is kind of in a strange position, but looks correctly to the north, where Mrs. Paley comes from. Simon and Jerry both knew where to look before the door opened, so it's reasonable to assume that it's easy to tell which door is opening, so Max shouldn't have looked at any other door.
Other mistake: The skull they used for the little girl in the well is obviously an adult's skull.
Other mistake: On Caroline's uniform, you see the American flag patch on her right arm (I think it's her right anyway). The flag is backwards. Flag patches worn by military and government officials always has the stars in the front with the stripes following.
Other mistake: When Emery awakens from his nightmare his clock reads 1:20 a.m. But in the following shot, a grandfather clock in the hallway strikes 2am, but its hands are at 12:00 am.
Other mistake: Sy enters the SavMart (after being fired) with a large photo envelope in his hand, and the boss who fired him confronts him about going elsewhere to process his photos, and they get into it. Then Sy pushes past him, and in the next shot, walks right up to the photo counter, when in all previous scenes, the photo lab was at the back of the store.
