Revealing mistake: After the bounty hunter, who changes three times throughout the movie, changes into the Reverend, he is in front of someone else who is a stand-in for the real Reverend but is obviously not.
Revealing mistake: At the beginning, when Ivan and the two New York businessmen approach the school, the three are seen through a window from inside the school. If you pay close attention to the reflection of the students in the window, you can see that they are in no way doing anything related to what is being heard inside the school. After the class is dismissed and starts to leave, we see Ivan and the two businessmen begin to enter the school, and if you look in the window, the class is still going hard. (00:03:00)
Continuity mistake: When Eddie and Michel are in the police station and Losado comes to pick up Michel, her hair clip is on the left side of her hair. After Losado and Michel get into the car, her hair clip moves to the right side.
Continuity mistake: When Jim pushes John out the car, in the shot where John is lying on the road, his head is on the road's white stripe, yet when it cuts to a closer view, his chest is on the white line, not his head. (00:12:30)
Continuity mistake: At the end of the movie, Spence is seen with Claudia in a western movie. He walks through the swinging bar doors with a cigar in his mouth. He takes a few steps forward and the size of the cigar has nearly doubled.
Revealing mistake: When Lazarus and Klepper's vehicle goes through the wooden crates and flips over, you can see the wooden ramp used to launch the car.
Visible crew/equipment: When the Overlord is busy destroying the Diner, when he starts destroying stuff on the counter, you can see the small rods pop up that flip the saucers and glasses into the air. You can also see the compressed air they used, to aid with the effect.
Continuity mistake: When Max and Joey take a picture at Luigi's house, Joey is looking at the camera and not smiling while Max's hand is just below Joey's right ear, getting ready to grab it. When Max makes a copy of the picture later, Joey is looking away from the camera, smiling, and Max's hand is on Joey's shoulder. (00:50:50 - 01:14:40)
Continuity mistake: At the funeral, the name shown in the coffin is 'Micheal Wong'. Later in the film, in the scene where Michelle takes a look at the coffin, the name has changed to 'Michael Wong'.
Continuity mistake: In the scene where Remy finally figures out that Ann has some serious questions about his dept., he pushes her against a tree. When the camera is on him, her necklace has swung around to the back of her dress. When the camera is on her, the necklace is 1/2 inside and 1/2 outside the front of her dress. This switches back and forth several times.
Continuity mistake: In the scene where the Volkswagon is sinking in the water, the first shot shows Chuck Norris diving off the car roof and he starts to doggie paddle. The next shot is of Melody Anderson swimming and behind him, Chuck is still on the roof of the car. The next shot, he is back in the water again.
Factual error: In the scene where Tommy Lee Jones's character shoots down the helicopter. The helicopter has a Canadian aircraft serial number - C-GLCD. Since it's being used by the New York Police Department in New York's Central Park we should expect it to display an American registered serial. (00:53:30 - 00:54:30)
Visible crew/equipment: The safety line of John Stamos' stunt double is seen as von Ragnar throws Lance over the dam's top rail.
Continuity mistake: As Tuba's story about the folk-dancing at the funeral becomes exponentially more ridiculous, the man in the pink shirt tries to convince his wife, but there's a clear lack of continuity in his movements between the various cuts. (00:11:15)
Other mistake: Lakella seems to disappear from the movie after the battle.
Other mistake: The end credits are plagued by the biggest compilation of spelling mistakes you'll ever see. The French cast in particular has 2 out of 2 actors with their names wrong (PallarOy instead of PallarDy, a female, Danièle, turned into a male Daniel) and so many errors in the technical cast to make some of them impossible to identify.
Visible crew/equipment: In the opening sequence, Sammo Kam-Bo Hung is scavenging the dead soldiers (with one hilarious twist) - however, when he is holding the ring, in his sunglasses you can see several very much alive crewmembers standing. (00:02:45)
Continuity mistake: Martin McNamara calls his brother at the beginning of the movie and tells him he'll be ready in two minutes. When the camera cuts to a new shot, his grip on the phone changed entirely.
