Deliberate mistake: When Jojima's car is blown into the air, one of Ryuuichi's thugs throws a knife at it. When Jojima gets out after the car crashes to the ground, the knife is stuck in his stomach. This is physically impossible, as the knife would have to go through a large portion of metal to hit him there.
Deliberate mistake: When Sidney is typing the message to the police, you can see that there are red lights flashing, which must mean the police are there, 5 seconds after she types. Obviously deliberately done for the humor. (00:29:30 - 00:30:25)
Suggested correction: Contrary to what the entry says, I don't see police lights flashing as she types, nor when she talks to Billy. I do agree that still it's barely a minute before the police arrive in full force on the scene and it's pretty ridiculous (although I am not sure it's deliberate humour).
There's a time skip between Sidney encountering Dewey at the front door and Billy being arrested. It's plausible Tatum had sent Dewey to check on Sidney knowing she was going to be late, and so he arrived before the rest of the authorities. Billy did not chase after Sidney and likely reacted calmly to Dewey to look as innocent as he could, he wouldn't necessarily have been arrested right away.
Deliberate mistake: When Laurence Fishburne goes to Reva's car when she delivers Tre, Lawrence's face can be seen in the inside rear-view mirror as he kneels down on the passenger side.
Deliberate mistake: In many scenes bullets are shown striking things and sparking (this is especially visible on the attack on Knockout Ned's house when a bullet strikes a chair and gives off a huge spark of light). In real life, only special bullets with incendiary materials (meant for starting fires) cause sparks, and this is only when they're fired against metallic objects. It is impossible that a bullet striking a chair would give off a spark.
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: The same shot of the railway station concourse is used when Graham and George are heading to work, and also when George commits suicide. The giveaway is that several people are seen in the same position. (00:05:00 - 01:20:30)
Deliberate mistake: The floating contact mine that explodes at the end of the movie would never have been put in an evidence room in a police station. Barring that error for the plot's sake, FCMs weigh 450lbs and would have required a hydraulic crane and a cart to move it, not just a couple of guys. They also did not contain clocks. (00:42:40)
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: In the scene where the boys scratch off the paint on the window so they can look at the ice skaters getting dressed, there's a grille about 6 inches from the window. When viewed from outside their faces are pressed against the grille, but when the shot changes to inside the building looking at their eyes moving, their eyes are much closer to the window than the grille would allow. (00:09:30)
Deliberate mistake: It is shown throughout the film that card keys are to be used to open the hotel room doors; this is a security measure that is used for doors in elegant and expensive hotels (if not all). There are no hotels that use this measure without having break-safe metal material inside of these doors, yet the killer and cops are shown breaking down doors fairly easily. Add to this the fact that only thin slices of wood are shown breaking off of the doors, not metal nor even the card-keying device.
Deliberate mistake: When everyone is surfing at night, the sound of the waves in the background is significant, as it should be. However, at one point, when Keanu and Lori are having an intimate conversation on the water, the sound of the waves disappear. The wave sounds resume in the next scene.
Deliberate mistake: When the fight first begins on deck of the sub, a henchman jumps from the hatch and picks up a wrench that was lying on deck. If the sub just surfaced, where did that wrench come from?
Deliberate mistake: The tanks used in the film are German "Leopards", never used by the US army.
Deliberate mistake: When Carlo and Bonehead go upstairs to confront Jack at the hotel, Bonehead accidentally shoots Carlo in the leg and Carlo fires eight shots in retaliation at Bonehead killing him. Carlo immediately bursts into Jack's room same gun drawn. When Jack jumps out the window Carlo begins firing and shoots another 15 times. There is no way the single clip in the gun Carlo uses could possibly fire 23 rounds.
Deliberate mistake: The eyewitness testimony that placed Oswald in the lunchroom at the book despository didn't come to light until the House Select Committee on Assassination in 1978, many years after the Shaw trial.
Deliberate mistake: During the final scene, where Dom and Brian are dragging, you clearly hear that the Dom's car is straight piped. When the Charger (Dom's car) is spinning, you see that the car has a complete exhaust system.
Deliberate mistake: The number of acts Lecter performed during his escape from the individual jail cell and until he was attended to by an officer (who thought he was an injured officer) would have taken a lot of time and effort to complete - way more time than he could have gone undetected by one of the many officers in the building. Slashing/ bludgeoning to death a person can be done fairly quickly (munching on a victim's face adds time!), but three particular acts required a substantial amount of time, especially for an elderly man whose ultimate goal was escape: Swapping clothes (undressing and dressing) with a police officer and trimming off his face/scalp to appear to be that officer, then getting to a strategic location to be discovered; Setting a dead officer on the roof of the elevator; and, somehow hanging / impaling (crucifixion-style) an officer from the top of the jail cell (which appeared to be around 10' high). The latter feat would be challenging for TWO physically-fit officers.
Deliberate mistake: When the media truck follows Mel, he comes to a traffic light and stops. When he throws away the van's keys, he speeds off from the intersection. Why are the cars at his left not driving? They look like they have parked there and with no drivers present in the car. Weird for a very busy road.
Deliberate mistake: While in the Japanese bath you see the fat samurai swim in the "pool" with an underwater camera. But when on the surface you can see the "pool" is no more than a man's length, in other words he could not have been swimming in there. (00:42:45)
Deliberate mistake: When Gregor is holding a long lens camera in a cafe house, he is pointing it at two men, you can see this when he looks through the lens, yet the next shot of through the lens is not from his camera but more like from a person standing right next to the two men. (00:59:40)
