Continuity mistake: When they have rolled all the weed together, Dante lit the bong with both of his hands on the bong, but in the next shot he is just sitting back on the couch.
Continuity mistake: During the jail breakout, when Jake tries to open the ORV's door, in the shot facing Francis he is holding the gun in his left hand as he tries to open the door for his brother with his right hand. In the next shot facing Jake just before shouts, "I don't have the handle, open the lock!" Francis's gloved left hand is empty, and next shot, the gun can be seen in his right hand. (00:01:45)
Deliberate mistake: When MIB agents exit the lift to get into the main hall of the MIB Office, the lift opens halfway up the wall and they need to go down a little platform. But when K and J return during the lockdown and face the trashcan with guns, the lift opens at floor level, so it can be conveniently peppered with bullets. (01:02:05)
Suggested correction: The building is in lockdown so it is no surprise that the lift is changed to a less flamboyant version. Even in the first scene, there are some doors there.
Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Other mistake: In the beginning of the movie, when you first see Mary-Kate (aka Mel) and Ashley (aka Ally), Mary-Kate walks off without ever closing her locker.
Continuity mistake: As the hand creature busts the shackles off Boris' legs in Lunar Max, you can see the bottoms of his pants over his metal prison boots. There are only a few folds and wrinkles over his left foot, and the pants over right foot are hardly wrinkled at all, or affected as the creature climbs up his right leg. But only a couple of seconds later, we see another shot of Boris' feet as the creature breaks off the metal sleeve of his arm, and suddenly his pants legs are very wrinkled. Boris was standing perfectly still the entire time. Boris' legs are also suddenly closer together. (00:03:35)
Factual error: Dutch police cars don't look like they do in the movie, with their blue and white checkerboard pattern. They had blue and orange diagonal stripes on the side. In this movie, they look much closer to what British police cars look like.
Factual error: In the movie, we see the Statue of Liberty with its current bluish-green color. The statue only got that color over time, and as it was still being built, it should be its original brown.
Visible crew/equipment: At the party towards the end, Sherman leaves and Carla comes after him. As she runs toward him, the battery pack slides down her leg.
Continuity mistake: When Frankie is fighting Mitch and gets thrown off the balcony the diaper bin on his head comes off, but in the next shot when he lands in the pool it's back on his head.
Revealing mistake: Near the middle of the movie Samantha Mathis is walking across the high school campus. The name of the high school in the movie is "Hubert Humphrey High School, " but behind her, above the library door, a sign says "Saugus High School Library". Shows better in 4.3 aspect. (00:31:45)
Plot hole: When Andy turns into a werewolf, he kills both Amy and Detective Benbou. Later in the morgue, Amy tells him because of this that she is forced to become his "rotting sidekick." If this is completely true, then Detective Benbou should also be following Andy around but he isn't seen after Andy manages to escape from the morgue.
Plot hole: Ted calls on John to tell him that he saw Lori leaving her apartment with her boss. How did he find him? He turns up not only at the right hotel but the right room! They have had no contact since their fight after the party and Ted hasn't been asking around after John as he tells him he 'just saw' Lori leaving with her boss. So how did he find John? Is he psychic?
Suggested correction: A week has passed since the breakup and we don't see anything that happened during that time. There's nothing in the film to indicate Ted didn't try to reconcile with John (such as through text) or at least find out where he's staying. The only reason Ted decided to go to the hotel is to tell John about Lori leaving with her boss because he knows that would be a big deal to him. And Ted went to Lori's to try to get her to take John back (probably because of things John said to Ted during the week we didn't see). Once Ted is at Lori's and sees her leaving with her boss, he goes to the hotel to tell John he "just saw her leave" with him.
John had no reason to tell Ted where he lives, he didn't want him to come at all, that was shown. Ted wouldn't know where to go.
Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.
Suggested correction: He was using $1000 bills. That's 300 bills in the belt which spread evenly absolutely could have been missed near his waist as part of his clothing.
Rubbish. I specified $1,000 bills as that would be the smallest package he could have secreted about his person, and it would still be instantly detectable. If he used $100 bills the package would be ten times larger, and he would have to carry a rucksack under his shirt.
Continuity mistake: When they are driving to the hotel both the limos have tinted glass, but when they arrive at the hotel John Cusack's limo no longer has tinted glass - we clearly see him inside the car, although the camera's outside.
Continuity mistake: During the interview, while sitting, his striped pants are unzipped for a few cuts, then they are zipped in later shots.
Plot hole: Shortly after the robbery, Kevin Kline and Jamie Lee Curtis get together in a little flat and Kline calls the police from a landline to tell them who committed the robbery. In England this would immediately lead the police to the flat from which the call was made, and the person reporting the robbery would be the first person the police would want to find and speak to. Otto has handed it to them on a plate. (00:12:29)
Continuity mistake: Towards the end when Debbie and Danny get into a fight around 5am at their apartment, Debbie packs some things and goes over to Joan's apartment to mull it over with her. While they're talking with Joan in her robe, Joan's hair goes from being up in a hairband (not even visible out of the hairband) to her hair being down and styled with no hairband at all and then back to up to not visible in the hairband again.
Revealing mistake: When Cindy and Buddy get trapped inside the cold chamber, she starts rubbing him to a point that it becomes masturbation. But when she's sitting on his legs doing the thing, in one side shot you can clearly see she is not holding his privates and her hand is just going up and down, closed but empty. (00:58:05)
Continuity mistake: Linus and Rusty are standing in the Botanical Garden at the Bellagio going over Linus' observations. Rusty has a cocktail glass of shrimp in hand. When they change angles he has a plate in his hand, then change back, it's a glass. Full screen version. (00:43:40)
