Continuity: When Danny meets Sam the second time he is bleeding on the floor. When he falls to the floor the amount of blood on it differs between the shots.

Continuity: In the scene where Jet Li grabs the steering wheel of Bob Hoskin's SUV and they crash and flip over, the side view mirror on the right side breaks off and reappears several times during the crash. Also, when the SUV flips over, one can see a large flat panel on the underside of the car that disappears once the car has come to a complete stop.

Factual error: The registration plate of the white Jaguar refers to a year 2003 registration. This is impossible as this particular model Jaguar ceased production a long time ago, and could never have that plate. (Please note that British licence plates don't get renewed each year like for example US plates.)

Continuity: In the scene where Danny and Bart are fighting in Sam's house, they push the TV off onto the floor. A few minutes later, at the end of the scene, we can see that the TV is on the rack again, in its original position.

Deliberate "mistake": This was probably done intentionally to make them more visible, but the bullet holes left in the stairwell wall by Bart's handgun while he is chasing Danny during the movie's climax look to be about the size of golf balls. Typical handgun calibers aside, just looking at the size of the clip he's loading into the gun and seeing how many rounds it holds, those rounds would have to be much smaller than the holes the bullets made.

Continuity: When Sam reaches for Danny "necklace" Danny grabs on to it with both hands placing his right hand over his left. When it cuts his left hand is now over the right.

Continuity: In the scene where Danny and his uncle is riding down the road in a car, you see a Mack truck hit them. As the car is being pushed along, notice that the hood of the car is sticking straight up in the air and almost ready to fall off. After the truck stops pushing the car, you see some men drive up, get out of their car with machine guns and start to shoot at the damaged car. During the shooting take note of the condition of the hood - the damage is completely different from what you saw earlier.

Continuity: As Danny is reading his ABC book at the start of the movie, blood drips from his head. We then see him picking up something from the bed. As the camera changes back to the view of his face, we see that the blood smear has changed. The blood that was on his eyelid has now disappeared.
