Continuity mistake: When Bowen first catches up to Draco under the waterfall, he is completely soaked as he stands there and talks to him. Draco takes off flying and Bowen goes after him on his horse and is now completely dry, hair and all.
Continuity mistake: As the Doctor is being put to sleep, he lies on the operating table which has no pillow for his head. When Salinger uses the defibrillator on the Doctor, he has a blue pillow cushioning his head.
Factual error: When the boys have a night on the town with a bunch of eager Dutch girls, the girls somehow forget their native tongue and start to chatter in Danish.
Other mistake: As Plisken escapes in the hijacked chopper, Quervo Jones picks up a bazooka and prepares to fire on it. As Fast Eddy shoots him through the chest, watch the bazooka. You can see right through the barrel. In other words, there is no ammo in the weapon. (01:25:05)
Continuity mistake: When the Presidents jump off the moving train, James Garner pushes Jack Lemmon off first, waits several seconds, then jumps himself. Given the speed and direction the train was going, Garner should have landed quite a ways away, to the left of Lemmon. But he ends up only a short distance away, to the right of Lemmon (based on the direction they were facing when they jumped.)
Factual error: Towards the end of the song "Out There" Quasimodo climbs onto the large spire on the roof. That spire was added in the 19th century and thus didn't exist when the movie was set.
Revealing mistake: Throughout the movie the rescue helicopter changes. The paint job remains the same but they're two entirely different choppers. This can be most easily seen by the flat single-pane windshield of one and the round wrap-around windshield of the other.
Factual error: When Xander's thugs are taking the Phantom up to the roof to do away with him, he breaks away and ducks into the machinery room for the elevator. In the scene the door of the room is lockable from the inside only. This door should be lockable from only the outside.
Visible crew/equipment: When Angel Marie comes up to attack Fozzie, you can very easily see the forehead of the puppeteer, as well as the T formed by the human hand merging with the puppet hand.
Continuity mistake: During the scenes on the makeshift snowboard Jackie uses to evade the skiing soldiers, every time you see Jackie's face he is standing left foot forward on the board, but whenever you cannot see his face he is standing right foot forward. (00:19:45)
Other mistake: The Mongolian guy is supposed to be knocked out cold - however, he appears to smile upon being knocked down.
Continuity mistake: Throughout the flight with the seagulls attached to the peach stem, the length of the peach stem gets shorter and then longer and then shorter again.
Visible crew/equipment: A safety cable and harness are visible during the fight scene, on top of the industrial complex.
Other mistake: In the scene when Gunther jumps in the guy's car who doesn't pay him, he takes off the collection sheet and the holes for the clips are on the bottom. All holes for collecting books are on the top, so he is reading the collecting card up-side down.
Factual error: At the start of the movie Amy and her mother Alaine are in a car accident near Auckland, New Zealand. The ambulance is a US or Canadian ambulance, as New Zealand ambulances do not have the word paramedic on the side.
Factual error: Following their re-equipping at the South Essex depot, Sharpe marches his battalion across the bridge towards London. However, every non-commissioned officer is aware that troops don't march across a bridge. They break step to avoid setting up harmonics that would collapse the structure.
Visible crew/equipment: Whilst Dignan is leaving the motel, Inez gets Rocky to say to Dignan "Tell Anthony, I love him", to which Dignan says "All right, man, okay" and walks off. The following shot after this is of Dignan walking past the side of a building. Right at the start of the shot, for a split second, the reflection of the cameraman can be seen reflected in the window beside him. (00:48:45)
Continuity mistake: During Toad's walk on the road dressed in a tealady's dress, when the camera is at his feet, his green tights are pulled down to the shoe, but when Toad puts his foot on the stone sign his tights are all the way back up his legs.
Deliberate mistake: In the scene where Joan and the kids pile into the station wagon after Stanley is kidnapped, Joan tells the kids to hold on tight and puts the car into reverse. However, in the matter of seconds that have gone by, Joan hasn't even started the car, yet she was able to put it in reverse and drive off. Even if she had the skills to start it that fast, you would hear the car turn over. The car is never heard turning on.
Visible crew/equipment: After Thorne gets his "temporary permit" to go cut down the trees, he's seen getting into his vehicle. Above it, a boom mic comes into frame.
