Plot hole: Each of the four magicians are given a tarot card that has a date (March 29), a time (4:44pm), an address (45 East Evan St), and a city (NY). When they enter the building on that date, they know which apartment to go to. The problem with this is that it was never stated on any of the cards which apartment to go to once they reached 45 East Evan Street. (00:08:40 - 00:10:05)
Plot hole: Since they took down the telephone network, it would have been impossible for Justin Long to even be speaking to the emergency response woman for the car, much less send a signal to start the car up.
Suggested correction: Is it possible this is a satellite phone call akin to Onstar?
No, the BMW system requires a cell signal to work, which was taken down earlier in the movie.
Continuity mistake: Toward the end when Crews runs in with Red he first knocks his right headlight out, later it is back in, then it's out again. (01:21:40)
Other mistake: At 1:39:14 the bomb arms, 32 seconds later at 1:39:46 (two seconds after it should have blown up) Dan and Molly jump from the helicopter. Then 10 secs later at 1:39:56, the plane FINALLY blows up after giving them those extra 12 secs to jump and conveniently make it to the pool below.
Continuity mistake: Steve McQueen passes the same green Volkswagen at least three times while chasing the black Dodge Charger R/T. This is due to the same downhill portion being shown to us from multiple angles to artificially extend the length of the scene.
Continuity mistake: When they are in the Whitehouse, and Beavis has turned into Cornholio, he picks up the "Red" hotline phone on the President's desk, and is talking to the nuclear bomb officials. Later, when they are in the President's office again, getting their certificates, there is now a black phone on the desk, where the red one was. (01:03:05 - 01:11:00)
Other mistake: Dante and The Agency both have extensive photos and videos of the team's previous exploits. Trouble is that most of it is simply stills and footage from the previous movies in the franchise, often occasions when nobody was around with a camera to witness and document what was going on, certainly not at the angles we see.
Continuity mistake: When Sly is in the attic, and the fake power dude comes up to kidnap him, Sly uses a ski to "hit him in the gonads". But if you look closely at his face, the guy who was hit in the nuts wasn't the same guy that fell down the stairs.
Revealing mistake: When John Cusack is driving the actress, there is a shot looking over his right shoulder at the dashboard. The speedometer reads 0 mph. (00:08:15)
Visible crew/equipment: In the last scene where the main character escapes, he jumps into the bay and is supported by a sack which he is carrying. Actually you can clearly see that he is supported from underneath by a diver.
Continuity mistake: When Hutch tackles Starsky to the ground after his gun goes off in the disco, Starsky's badge falls to the ground beside his head. Hutch grabs it and holds it up, telling people to calm down, but when the shot returns to Starsky the badge is still there next to his head. (00:49:40)
Continuity mistake: Watch the newspapers on the front of the bus when Mos Def is getting off. At one point there is a big hole and you can see out, but in the very next shot a newspaper is covering it again.
Factual error: Worms are not created in AutoCAD. Ever. Period. Does not happen, cannot happen. Building design work and the like is done in AutoCAD. Viruses and worms are coded out by hand or created with a generator by slackers that don't know the code and then compiled into executables.
Continuity mistake: When Clouseau parks in front of the ministry of justice, he breaks the hood of two police cars. A few shots later, when we see him entering the building, only one of the cars is broken.
Factual error: During the first tunnel sequence, all the cars travel very far into the mountains, turn lots of corners, yet not only is Gisele still able to speak to them over the radios, their GPS still works. GPS signals invariably need a clear 'sight' of the sky and can penetrate light cover, but most certainly not that depth and cover. (00:58:05)
Continuity mistake: When Cage's character offers the money for his brother and the brother is in the car about to get crushed, the back window gets broken out twice. (00:15:55)
Continuity mistake: During the police chase, the hub caps on Saul's police car keep appearing and disappearing throughout the whole chase.
Continuity mistake: When Big Momma and Sherry park on the street in town the car they are in is a Mustang GT and when they get out and walk away the car is a Mustang LX. (00:42:10)
Continuity mistake: When Jennifer Tilly is in bed wearing some kind of skimpy pink thing, only one strap is always on her shoulder, but between shots it changes from left, to the right, back to the left, repeatedly. Every two or three shots.
Continuity mistake: Chili Palmer goes to DeVito's house and parks his mini van next to the curb facing one direction. When Chili gives DeVito the keys for a test ride, the mini van is now parked facing the other direction on the street.
