Deliberate mistake: When Morpheus is facing the twins' car, the road's not all that wide, and there are concrete barriers both sides of him. After he rolls to the side and slices their car, we see a side shot, quite far back from the road, and the barrier closest to the camera has disappeared (presumably so we get a better view). In a closer view, both barriers are back again. (01:29:25)
Deliberate mistake: Not only is the angle of the moonlight that shines through Jack's prison cell window intentionally exaggerated to enhance the shots with Jack, doggy, Koehler and Twigg, but in relevant shots, the moonlight is not seen coming through the window or the broken wall. Nor is it reflected on the floor outside the cells or in the cell next to Jack, particularly in the shots from the dog's POV looking up the corridor towards Jack. (00:36:00)
Deliberate mistake: Almost trivia, but not quite. When Mystique's looking through the guard files to find a suitable candidate, lots of photos flash up very quickly before she finds the guy she uses. Of note is that Bryan Singer pops up in guard uniform (with his own name), and so does someone called "Donner, L". This is most likely referring to Lauren Shuler Donner, one of the producers, and sex is specified as "F", but the photo is of a stubble-coated man. (00:23:10)
Deliberate mistake: In the Extended Edition, the location of the Tomb of the Stewards is shown to be behind the city of Minis Tirith, at the cemetery on the mountainside, accessible via a long bridge. Flaming Denethor later runs to the far prow of the city, leaps off and plummets. The distance between the two areas makes it is obviously entirely impossible for someone, even adrenaline charged Denethor, to run this distance while his oiled flesh burns. Admitted on the commentary that it's poetic license, due to director Peter Jackson's long awaited vision for this dramatic shot. (00:13:15 - 00:30:50)
Deliberate mistake: Bosley is a school crossing guard trying to help the Angels. The children behind them say they are gonna be late for school. Of course they're going to be late because there is not a school within 10 miles of where they are standing. There's trees and what looks like a huge mountainside on the other side of the street. You can see this more visibly as the car that is about to run over Bosley is approaching. Done for a gag, but still ridiculous. (01:09:05)
Deliberate mistake: In the scene with the first demonstration of the digging laser, they dig/blast quite a hole in the mountain. Even assuming the laser can very easily shatter the rocks substance, still the debris would have to go somewhere, yet there appears to be none. And the amount of power needed to convert matter into energy is not practical.
Deliberate mistake: After the game has entered the real world, and Floop and Minion are there to "save the day", Carmen and Juni throws seven pairs of glasses to them. But afterwords, we see there are only four pairs of glasses on Minion and one pair on Floop, which totals five. (01:11:10)
Deliberate mistake: The four main "good guy" characters are stuck on an island with people who are trying to kill them. Steven Baldwin's character brings a pistol and takes a machine gun from one of the bad guys. Several times they overcome other armed men, but after defeating them, never bother to take the bad guys' guns. At one point, two characters argue over who gets to carry the pistol, yet when they knock out a man armed with a rifle, they leave it with him and just walk away.
Deliberate mistake: There is one scene in the movie where Heath Ledger reads a Latin sentence in a book. As he is translating the sentence, he goes over the words one by one with his finger. This would never be possible in a Latin sentence, because words in Latin are never in exactly the same order as in English. Words that actually belong together can be placed at opposite ends of a sentence.
Deliberate mistake: When the two Confederate and Union soldiers meet across the river and trade coffee/tobacco, you can see the other side of the bank behind them. It looks at least 50 feet away, yet before they were able to talk to each other without shouting. Also, the Union soldier raises the pipe to his mouth in his right hand, which switches to his left in the next shot. There is also a mist present at the beginning and end of the meeting, but not in the middle. (00:37:55)
Deliberate mistake: When the platform Jackie and Rathbone are on falls, you can see a shot of a restraint snapping out of the floor. Two cuts later is the same shot, just flipped horizontally.
Deliberate mistake: When Jackie tries to avoid the Jamaican guy he jumps up to a higher deck. As we see him duck out of sight it takes him about 1 second to get to the other side and jump down there. However it's at least 40 feet to get to the other side. Jackie is usually fast but not that fast. (00:34:30)
Deliberate mistake: When Beck and Travis dive off the road and roll down hill, their stunt doubles are quite noticeable in many of the shots down the hill. (00:26:35)
Deliberate mistake: When you see one of Pascal's henchmen turn off the power, he is wearing a black suit. In the reflection of the glass on the power box, you can see 'Police' written on the jacket. The filmmaker chose this suit because it was black, thinking no one would see the police logo on it.
Deliberate mistake: After Mina leaves the car in Venice, Sawyer just manages to avoid several obstacles on the way, including a bend in the canal. But in the first scene, where Sawyer swerves the car around, its front should have slipped into the water anyway, considering the speed of the car and the tightness of the street, which makes a sharp L-turn at such close quarters next to impossible. But then the scene jump-cuts, and the car is well past the hazard.
Deliberate mistake: When Hulk meets his father at the lab, each one's eyes have a special light on them. This adds for dramatic effect, but it's absurd because there is no direct source of light since each one is in front of the other and their faces are in shade in the rest of the shots.
Deliberate mistake: When the teacher walks over the floor towards the blackboard, he walks through a lot of blood. However when it cuts, he leaves no traces of blood where he steps.
Deliberate mistake: When the Crazy 88 crew is coming in to attack the bride they use one of the shots twice. It is the one that shows 1 guy jump over a banister and go to the left of the screen then another guy comes directly after him and heads directly towards the camera. It happens at 1:21:49 and 1:21:53. (01:21:45)
Deliberate mistake: DVD version : When Seagal flees from the dig, the car he drives changes from left side control to right side and back. (in close up - you can see the seat to his left).
Deliberate mistake: When Jason throws Freddy to the wall in the burning house, you can see a window on the wall. Now, the distance between the window and the corner of the wall is about five feet. This gives Freddy space enough to hit the wall and not hit the window. However when Jason picks Freddy up you can see the distance has increased to about one feet. It's like they've put in an extra window where there should be a wall instead. (01:14:30)
