Deliberate mistake: After Wolverine arrives at 3 Mile Island he approaches through a thick fog. Above him are a series of conveyor belts that are used at a coal power plant, not a nuclear plant such as 3 Mile Island. The belts are unique to coal mines and coal power plants, and would not be found at a nuclear power plant. The filmmakers obviously couldn't film on the site of a nuclear plant, so filmed on a coal plant to fill in.
Deliberate mistake: On the roof of the sunken building, Bond tries CPR on Vesper, then quits when he realizes that she is dead and sits away from her body. Watch her right leg carefully when he returns to her body and cradles her in his arms - she flexes it upwards at the knee. Yes, I know that electrical impulses in a dead body can cause muscle movements, but this was obviously the actress involuntarily bracing herself from slipping on the slanted surface. Cut to Mr. White walking away with the money and when the camera returns to the roof, Vesper's leg is lying flat again. (02:18:00)
Deliberate mistake: When Red is shooting at Crews and Crews forces him off the road, the driver's front tire blows on Red's truck. You see it happen and see the blown tire again when he goes off-road. A few seconds later, Red drives away as if there is no problem. (00:58:05)
Deliberate mistake: At the end of the movie, where the girls chase stuntman Mike, they drive the upper dusty road. When their car is shown front outside angle, there's a lot of dust rising from the camera crew's car. But when the camera angle gets into their car and shoots strait ahead - the dust is all gone, the air is perfectly clear.
Deliberate mistake: During the space battle, one of Drax's men gets his back pack blasted. (1:46:37) His entire pack explodes so that his jet pack and life support are destroyed. But as a result of that blast, all the parts from his suit FALL DOWN! Even though there's no gravity.
Deliberate mistake: When Eric Kriegler shoots in the biathlon, the camera looks from behind the target, through the holes of the targets he has already hit. But in the next clip it can be seen that little flaps fall down and cover the holes when they are hit.
Deliberate mistake: While Hector is in the water with the crocodile, he yells to the female officer to start the helicopter by turning the key. It takes a lot more than just the key to start a Bell Jet Ranger helicopter. Fuel shutoff valve, throttle, key, and the main rotor doesn't start rotating until the throttle on the collective stick is turned to a specific position.
Deliberate mistake: The shots of the prisoner skiff during the transport to the Sarlacc Pit are reversed. This can, for example, be seen as Chewie's bandolier is on the wrong side, and that Han's shirt is overlaying the wrong way.
Deliberate mistake: Rather than using real Bruce Lee footage only for the final fight scenes, so the undisguised Billy Lo's different appearance might make sense after his surgery, the filmmakers instead spliced real Bruce Lee face footage throughout the early film giving the character a constantly changing face from scene to scene.
Deliberate mistake: When Lazlo is hiding the dollar bill in the painting, look closely and you will see the scene is played backwards. Ashes from his cigarette flies back up and smoke from the cigarette comes down. (00:22:35)
Deliberate mistake: When Connors becomes a humongous Lizard, his robe magically grows from a Medium size to an XXL. (01:06:50 - 01:17:45)
Deliberate mistake: When Alex is in the cabin opening the can the pull tab is already lifted up making it easier to open because he is wearing gloves. It was already up when he took the wrapper off.
Deliberate mistake: It would be impossible for anyone to push up on a casket lid six feet underground and make the lid move much less crack enough to get their whole body through, the dirt would fill the box and trap the occupant.
Deliberate mistake: The extras used in the scene when Danny gets assigned the case appear again as members of the jury. If Danny's colleagues were called as jury members for a trial all would have to declare a conflict of interest and be ineligible to hear the case. (00:09:30 - 01:03:25)
Deliberate mistake: When Sonya finishes Mileena, Mileena's shoulders are muddy and she is face down, but when we have a close up of the dragon tattoo the right shoulder is cleaned off and what mud is left is dry. (00:42:25)
Deliberate mistake: During the opening shot and titles, Neville is shown driving by the same block three times, each from a different angle. The first shot is high, the second shot (00:01:50) is from the hood of the car looking at Neville, and the third (00:02:40) is ground level.
Deliberate mistake: After the scene where Snipes gets an ID on Jagger from the little girl, one of the officers calls to inform Busey, "A scar under his right eye", yet you can see him form the word "left". I guess "right" was dubbed in to save a re-shoot.
Deliberate mistake: When the zombie (Tom Savini) is hit by a truck and spits a bunch of blood on the windshield, when he gets hit, the truck isn't moving at all. He runs into the car and spits blood to simulate being hit. It's hard to catch, but it's more obvious in slow motion. (Mentioned on DVD commentary.)
Deliberate mistake: O'Niel needs a sample of a dead man's blood to test for toxic drugs. So he visits the corpse, which has been dead for quite some time and is lying on its back, and proceeds to insert a hypodermic syringe into the dead man's frontal neck, extracting the sample. But blood pools low in the body soon after death. There ought to have been no blood available from that location of the body. To get blood, O'Niel should've punctured the corpse's underside.
Deliberate mistake: When Blade Abigail and Hannibal go to visit Dr Vance, Drake grabs Hannibal they move to a window, if you look behind them, the window is closed, then when Drake stabs Hannibal the window is open, then after drake goes out the window, you hear the window smash, even though he went out an open window. (00:56:15)
