Continuity mistake: In the White Power vs. Blue Power scene, Mike jumps and shoots a bullet in slow motion. While following the bullet, you can see one man take 3 or 4 steps, before the bullet hits Marcus's ass and eventually the guy's neck. (00:09:15)
Continuity mistake: In the "white power vs. blue power" scene when Mike yells "Marcus!", he fires both his Glocks. But in the following slow-motion shot, the bullet from the gun in his left hand is nowhere to be seen, although you can see he fires them in the same direction. In fact it probably would have hit Marcus, while the bullet from Mike's right-hand gun scrapes him in the bottom-cheek. (00:09:35)
Continuity mistake: After Marcus is shot in the butt, Mike shows up with a donut for his behind. When the scene shows Marcus from the front, Mike is holding the doughnut out. When the scene switches to showing Mike from the front, the donut is close to his face. (00:16:40)
Continuity mistake: When Syd arrives, the dog is swimming around in the pool in Marcus's house. In the next shot, just before the pool collapses, the dog is out of the pool and isn't even wet. (00:18:50)
Continuity mistake: During the shootout in the street, Will Smith does a sharp turn while shooting at the Haitians and ends up killing one Haitian who falls back on a car. A few shots later at a different camera angle, you see the same Haitian man get killed and fall back on the hood of a car. (00:20:00 - 00:31:55)
Continuity mistake: At the start of the long chase scene with the Haitian gangsters, the gangsters are running to their muscle cars to start chasing Syd. The orange muscle car has a noticeable dent/crumple near the right headlight. Later on in the scene, this dent is gone. (00:25:25 - 00:28:15)
Continuity mistake: When the Haitians have a shootout in the intersection, you see Mike do a 360 degree spin and then shoots the first Haitian in the green, but moments later you see Mike shoot him again. He was already dead. (00:29:15 - 00:30:35)
Continuity mistake: In the truck chase, the amount of damage to the front of the truck changes throughout. Keep an eye on the grill two pieces keep disappearing and reappearing. (00:33:10)
Continuity mistake: When the Haitians are on the highway, one of the cars fall off and is dragged by a chain and it hits the large black Ford beside it, with just a bridge wall. Then when the thug (the one who says, "Jesus f***") is shown inside the car, there is a Maersk Sealand vehicle there. (00:33:20)
Continuity mistake: During the chase scene, Marcus and Mike are being shot at. At one point the car headlight is shot out. The headlight is intact for the rest of the scene. (00:33:45 - 00:35:25)
Continuity mistake: During the freeway chase scene, the windscreen of the car first thrown from the top of the truck smashes out at least three times. (00:34:00)
Continuity mistake: In the highway sequence, you see a white car being pushed off from the top deck of the trailer, by the Haitians, and in the next shot it manages to land upside down. Also, the Haitians on the top deck of the trailer, are now gone. (00:34:15)
Continuity mistake: After the first car has been thrown from the top layer of cars on the trasporter, the windscreen of the car thrown off is seen to come out. The camera changes and it's back on the car. The camera changes again, and the windscreen pops out for a second time. (00:34:25)
Continuity mistake: In the freeway chase scene watch the boat's engine compartment cover. When the Mack truck knocks it off its trailer the lid comes off but then the boat gets hit by the car and turns perpendicular to the road and you see it come off again. (00:36:25)
Continuity mistake: When Syd gets out of the back truck after the high speed chase, she has blood on her nice white suit (probably since the guy next to her in the car was shot in the head). However, when she gets out to talk to Mike, her suit is clean and white again. (00:37:00)
Continuity mistake: After Syd is chased down in her black truck with the money in it, she meets up with Mike and Marcus. As she is talking to Mike, her bangs change positions. They go from down, to put up. (00:37:35)
Continuity mistake: When Joe Pantoliano is circling "tactical narcotics team" after the car chase, check out the circle. When he draws it, both ends meet nicely. Next time we see it there's a curve at the end of one line, and the next time they meet again. (00:38:30)
Continuity mistake: When Marcus and Mike get back to the station after the chase, the captain underlines "tactical" poorly, missing most of the word. When they walk to the captain's office, the underline is now visible under most of the word, obviously a different line. (00:40:10)
Continuity mistake: When Mike and Marcus are getting in trouble after the car chase on the bridge, watch the incense burning on the captain's desk; it keeps getting longer, shorter or whatever combination. (00:41:05)
Continuity mistake: Near the end of the shootout scene in the pink house, Mike starts to bring his gun up to shoot the Haitian through the wall, and the gun is empty - the slide is back. When the camera changes the slide is forward - indicating the gun has bullets inside. He then shoots through the wall killing the Haitian. (00:51:25)
