Revealing mistake: How on Earth can Selby get those skin tight T-shirts over that huge cast on her arm? They cannot possibly stretch any more than they already are - look at the scene where she and Eileen are checking the mail. There is no way that sleeve would fit over the cast without ripping! It is well beyond the capacity of that tight T-shirt to stretch to that extent! Obviously Christina Ricci had the cast fitted after she was in costume.
Revealing mistake: The road leading out of the samurai village has distinct tire tracks from vehicles.
Revealing mistake: When Sean Penn is in the funeral home looking at his daughter's body, when he lays the dress over her the rise and fall of the very alive actress' chest is visible as she breathes. (01:07:40)
Revealing mistake: Near the end of the movie, after Jude Law has been shot, he is lying on his back with Nicole Kidman leaning over his face. In the shot looking up at Kidman past Law's left ear, you can see the webbing for Law's wig on his left temple.
Revealing mistake: After the first race, when Tej walks over to Brian with a bunch of people, there is a girl in a orange and black top, and as she walks towards Brian, she is looking directly at the place where the camera is supposed to be and backs away, so the camera can pull in for the shot. (00:13:10)
Revealing mistake: In the overhead view of the bus driving across the desert to Camp Greenlake the dust behind the bus is CG, and near the end of the scene the bus moves up in the frame and the end of the dust trail cuts off with a straight line.
Revealing mistake: In the scene where Jalil and Smokey are talking on the race track, after Jalil wipes out in his race: if you look behind Jalil when Smokey leaves, you can see that the man sweeping the floor in the stands isn't actually sweeping at all - his broom is inches above the ground and he is simply sweeping air.
Revealing mistake: Near the end of the movie, when Johnny Depp's eyes are removed, he talks with the boy when he's against the wall. In several shots you can see Johnny Depp's eyes through the sunglasses. (01:33:55)
Revealing mistake: In the scene where Ray and Eva have sex for the first time, Eva is moving underneath the blanket and you can see that she has a pair of knickers on. The couple were supposed to have just finished having sex, why would she have knickers on?
Revealing mistake: In the big scene at the children's show when David and Natalie are revealed kissing behind the curtain, many members of the audience are shown snapping picture after picture. One of the guys who is snapping away very rapidly has a "throw-away" one-time use camera. All one-time use cameras have wind wheels, meaning you can't take photos that quickly. (01:54:15)
Revealing mistake: In the scene with the press conference, as Chris is making her way to the front, journalists are holding cassette recorders out, as if seeking comment. The problem comes in that they are playing their recorders, but not recording, since the play buttons are pushed, but the red record buttons are not.
Revealing mistake: During the major fight sequence in the Corporation, Shannon defends against two people each having the same problem. Their weapons are made of rubber. First a man shoves a gun at her. If you slow down the picture, you can see the gun flopping back and forth. It's the same way with a knife a few minutes later.
Revealing mistake: The Acheron fires many devastating blows on the Surprise and the effect is visible in close-ups and a wide shot. However, after Mr. Mowett yells, "Relieving-tackles on the tiller! You men collect the wounded!" there is another wide shot of the Acheron in the foreground and Surprise in the distance. In this shot Surprise has NO damage whatsoever! (00:11:00)
Revealing mistake: In the Fredericksburg battle scene, just after the Union officer orders the men to fall back, there is a 1 or 2 second close-up shot of a Confederate soldier taking a hit and falling back. As he does, a modern wristwatch is visible on his left wrist under the sleeve of his coat. (01:49:49)
Revealing mistake: In several scenes of the zombies swimming under water, they are obviously holding their breath. Would a dead zombie need to do that?
Revealing mistake: When Dae-su enters the room of one of his nemesis, his computer screen shows information about the stock exchange. The Internet address on the screen is: C:/DocumentsandSettings/[.]/OldBoy/[.], which would be a link to a folder on that computer, not an Internet address.
Revealing mistake: In one of the flashback scenes at the "bunker", a number of the shots fired pierce the sheet metal roof. When they show these holes, you can see fairly bright light coming through. This scene was supposed to be in the jungle during the night. There shouldn't be light streaming in; moonlight is not that bright. It was obviously artificial light used to enhance the scene.
Revealing mistake: After William Macy interviews Jeff Bridges and when the narrator is describing Seabiscuit's fans (the scenes are about an hour apart), you see shots of people in trees. They are the same shot.
Revealing mistake: When the "light rail" vehicle is crossing the bridge, several shots reveal that it is not traveling on rails, but on a metal grating. This is most obvious after the police have stopped it. We see a bridge deck designed to carry cars & trucks (in fact, the police have just driven out on it) with strips of metal laid on the surface to simulate "rails". As others have observed, this was filmed on the wrong bridge; this makes it particularly obvious.
Revealing mistake: At the beginning when cutting the tomatoes onto the buns, Bob is not even coming close to the tomato in his hand, yet slices are falling off onto the buns. (00:03:50)
