Revealing mistake: Mirrors were used to make the corridors appear longer, early in the film when Brett is complaining to Parker about the way they are treated by the company you can see their reflections in the mirror behind them as they walk down the corridor. It's only for a second as they are moving off camera but you can see them in their white overalls.
Revealing mistake: When the Enterprise is leaving its docking station and pulling out, two little bugs or debris from the model lands on the camera lens on the lower left corner (corrected in the Director's Edition).
Revealing mistake: In the major helicopter scene when Ride of the Valkyries is played, the actual tape isn't going over the playing heads. (00:37:29)
Revealing mistake: During the end scooter sequence along the cliff tops, you can clearly make out wheel tracks stretching out ahead of Phil Daniels' bike, yet he hasn't been over that ground yet - these are presumably left-overs from a previous take?
Revealing mistake: When the sniper is shooting the cans, the close-up of the first can shows the metal peeling out as though the bullet had come from inside instead of outside.

Revealing mistake: There is a scene which features a nighttime view of Carfax Abbey, Dracula's home. This movie was set in the late 1800's/early 1900's, but if you look closely at the left-hand portion of the screen, you will see the lights of an airplane as it flies in the skies above the castle.
Revealing mistake: When the blind man is telling Brian he can see again and falls down in the pit, you can see the white mattress that he lands on. (01:01:10)
Revealing mistake: You can see the stick making the finger move when it's in the box. (00:38:20)
Revealing mistake: When Godell is trying to get away from the company's goons, he races to the nuclear plant gate where he'd be safe. As he pulls up to the gate, you can already see the 'donut' skid marks left in the driveway from the goons' car when it turns around. But the car turns around AFTER Godell pulls up to the gate, so the donut must be from a previous take.
Revealing mistake: When the Ferris Wheel at the theme park has broken from its mounting and is rolling down the pier, it appears to be rolling forward but rotating anti-clockwise when if it is rolling forward it should be rotating clockwise.
Revealing mistake: When the motorcycles are chasing the guy and his girl in the red car, one of the motorcycle riders attacks the car with a machete. He first hits the side of the car, and then goes to hit the windshield. Notice the windshield is already cracked prior to the machete making contact.
Revealing mistake: In the final battle between Jackie and the main villain's henchmen, the villain throws burning alcohol at Jackie. Jackie puts out the fire the first time. The second time this happens and Jackie is rolling to avoid the flames, you can see his left leg of his trousers is already burning even before the flaming alcohol reaches him. (01:28:40)
Revealing mistake: As Holmes and Watson are riding home from Watson's stay in prison, in the background double traffic lines are visible as are concrete traffic barriers. These are a modern invention and out of place.

Revealing mistake: When Dan Holland, Kate, V.I.N.CENT and old Bob battle Reinhard's robot sentries on the catwalk, part of the bridge the sentries stand on is critically damaged and collapses. In that shot, the sentries are model figurines.
Revealing mistake: You can see Jackie's knuckles are already bloody BEFORE she starts pounding on the closet door.
Revealing mistake: When the boy accidentally hits the old man with the ball, he falls over. Note that you can see the stuntman's full head of hair as he hits the ground. When you return to the close-ups of the old man as he gets up, that extra hair is gone.
Revealing mistake: At the start of the movie it's night and raining, but you do not see any drops of water hitting a surface anywhere although/but things appear to be wet. (00:00:58)
