Visible crew/equipment: In the last scene of the movie where Mike and Marcus are both in Marcus's "new" pool, as soon as the pool collapses into the ocean, you can see in the background a crew member standing there as if he was there to "break" the pool and in a quick shot back to where the pool was, he is gone. (02:20:35)
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)
Visible crew/equipment: At the end of the MacArthur Causeway chase, there is a shot of a police car spinning on its underside. A camera is seen sliding on the road, moving offscreen. (00:36:45)
Visible crew/equipment: Just after the chase scene with all the bodies falling out of the black van, you see one of the bad guys jump over a fence while he is running away, as he lands you can see the mat that he is landing on to soften the blow. (01:28:20)
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: When Tapia is talking to the guy about severing his head then threatens his family, he takes the pictures out of the box and the pictures are facing Alexei, but in the next shot they are facing Tapia, as he turns them around to show him. (01:05:45)
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 chase scene with Syd and Lowry, Lowry's Ferrari has silver brake calipers in a close up shot, but in a following close up they are a different style and red. The rims are entirely different as well. The scene is filmed with two different Ferraris. The original car is a 575M (red calipers), the other a 550 (silver calipers).
Continuity mistake: In the final shoot out Mike is wearing Oakley M-frames with a clear lens, but the lens shape changes three times during the course of the fight, from the sweep lens, to the strike lens, to the heater lens. (02:07:25)
Other mistake: When Marcus and Mike are in the Haitian penthouse and are "questioning" the dead, Marcus asks the dead man for info, he is slumped over but is obviously breathing. (00:52:45)
Audio problem: The sound is off when Marcus and Mike are in the video store talking about "The Box". It's most visible during the over the shoulder shot of Mike miming putting the word "flaccid" in the box. Mike's mouth is CLEARLY not in sync with the words that you hear. (00:56:35)
Revealing mistake: In the highway chase scene, when the car's been shot from the outside, you can see that there is only one person inside.
Revealing mistake: When Mike is saying "shoot outside the car" the background outside the car is completely still, despite the fact Mike is still driving at speed. (00:34:10)
Continuity mistake: After the pool incident, Mike's face appears in shade or full sun depending on the angle.
Continuity mistake: Just before smashing through the wall in the Cadillac vs. funeral van chase, the van apparently hits some vegetation before smashing through a fake brick wall. The attached vegetation changes between shots and is completely missing in some. (01:24:15 - 01:27:00)
Continuity mistake: Just before Mike smashes the car into the building, after chasing the morturary van across town, there is one quick shot where the windscreen doesn't have any bullet holes in it, despite there being three holes in it just prior to this. (01:27:10)
Other mistake: When driving through the shanty village huts are exploding nowhere near where the vehicle is driving. (02:14:15)
Continuity mistake: After driving through the shanty village, the cracks in the Humvee's window disappear. (02:13:40 - 02:14:55)
Factual error: Near the end of the movie, right after they arrive at Guantanamo Bay and Smith fires both of his remaining bullets, Tapia puts him TMP SMG and you hear a hammer being cocked. The TMP has a internal striker much similar to Glock, so you wouldn't hear anything. (02:16:35)
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)
