Factual error: Towards the end of the movie when Andy is escaping, he breaks open a sewage pipe and is covered with its contents. It is physically impossible for the sewage to shoot out of the break like it did. In order for that to happen there has to be pressure. But there is none there, because the end he crawls through is empty and the end is in the open air. (01:52:20)
Revealing mistake: When The Mask is dancing with Tina and he turns her into a human tornado while spinning her around, none of the onlookers in the crowd show the slightest bit of amazement at the impossible feat that just occurred in front of them, indicating that the extras were not directed to react to the special effects.
Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.
Deliberate mistake: Both in the first scene and last scene of the movie, we see Yolanda and Ringo starting the robbery by jumping from their seat and start threatening the costumers. In the first scene, Yolanda says "And I'll execute every motherfucking last one of you." But in the last scene the line changes to "and I'll execute every one of you motherfuckers". (00:04:40 - 02:18:00)
Suggested correction: Tarantino has explained that this is not an error, rather, he did this on purpose. When we first examine the scene, we are seeing Ringo and Yolanda's conversation from their perspective. Obviously, because this is their conversation, what we hear first is probably what was actually said. However, at the end of the film, what is said is different because we are no longer viewing the situation from Ringo and Yolanda's perspective, but rather everyone else in the diner, most specifically Jules.
Sounds like a typical Tarantino excuse for a stupid blunder.
Continuity mistake: In the movie Christie Swanson drives a BMW 3 series coupe. In the scene where they were making love the car suddenly changes to a four door model then back to a two door. (00:06:10)
Deliberate mistake: Twice in this film Axel is shot at by multiple gunmen using automatic weapons at close range - and they all miss. In the Earthquake theme ride the bullets ricochet of the rails at Axel's feet. Why are they all aiming low? Why don't they raise their aim? In the park outside he hides behind a perfectly ordinary park bench and the bullets hit the wooden slats. Not one goes through the open spaces between them? I know bad guys can't shoot straight in the movies, but this is ridiculous ...
Continuity mistake: In the bowling scene, beer froth disappears from one bowlers face after they howl. (00:15:20)
Continuity mistake: Towards the end of the movie when Chaz and the band are rebelling on stage and wrecking all the equipment, there are a few shots where you can clearly see that Brendan Fraser is only pretending to smash his guitar. (01:26:20)
Factual error: In the beginning of the movie, we see one of the two journalists playing "The Game" in a Game Boy. The other journalist says that the game is available in cartridges and floppy disks. The problem is that the guy playing the game doesn't even has a cartridge inserted in the Game Boy. It's impossible to play ANY kind of game in a Game Boy, if the Game boy doesn't have a cartridge inserted in it.
Continuity mistake: At the beginning of the wedding day scene when Mallory is throwing the red doll off the bridge, her nails are long and manicured, but later in the same scene you can see that they are bitten down to the quick. (00:19:55 - 00:21:50)
Continuity mistake: When Frank is going to look for a disguise he drives into a parking meter. The way the parking meter lies on the hood of the car changes between shots. (00:18:20)
Continuity mistake: After Leon rescues Mathilda from the SWAT team and dodges the snipers, he shoots out a ventilation fan to make an escape route. He gets off two shots before we see the vent, but when it does we see about 7 bullet holes around the vent. Then the camera goes back to Leon as he continues firing. When the camera switches back, the holes around the vent are different. (01:27:05)
Visible crew/equipment: When Angela and Shame are in a car chase from the bad dudes, Shame turns the jeep around 180 degrees and then drives over the bad guys' car. While the jeep is driving off the bad guys' car, you can clearly see the jeep driving off some kind of ramp set behind the car. You can just see them driving down it.
Visible crew/equipment: A boom mike is reflected in the car window, when Alex pushes Hugo's car into the lake.
Continuity mistake: During the trial when Beverly is cross-examining Mrs. Ackerman, her neighbor, she asks if those were her scissors found sticking out of Mrs. Sterner's stomach. That's not where the scissors should have been found. After stabbing Mrs. Sterner with the scissors, Beverly pulled them out and threw them at the husband twice, both times they ended up sticking in the walls, and that is where the scissors would have been found when the police arrived.
Continuity mistake: In the scene when Rudy is holding a colt python to the hotel owners nose, in the next shot, the gun suddenly changes to a smith and wesson revolver.
Continuity mistake: In the Baskin-Robbins scene, Tim's ice cream dish goes from full to empty to full again. His spoon changes positions as well.
Visible crew/equipment: When Honora brings Pauline a tray of breakfast into her room, Honora gives her the tray then talks to her for a while. You can clearly see the face of a crewmember reflected in a window, and then after, you see the reflection of two hands holding the long pole of the boom mic! (00:37:40)
Continuity mistake: When Lloyd's mother is tied to the chair, the red ribbon changes between shots. When viewed from the front, there are three wraps closely spaced near her shoulders. When seen in the close-up from behind, only one wrap is visible but there is a big space below it where the next wrap should have been.
Continuity mistake: During the final basketball game, when Shep makes a finger roll for a layup, his jersey and 15 are backwards.
