Continuity mistake: The President's assistant asks him the first time we see him "Roses or tulips?" George appears out of the blue in the next shot despite being barely (perhaps) visible at the very end through the side door, while the other people in front of the President were exactly where they are in the new shot. (00:06:30)
Continuity mistake: Darius Stone is fighting the first two wardens, the ones who have him in cuffs. One of them decks the other by mistake with the baton; the stuntman goes down on the ground next to Darius, face first, in the wide angle, but the actor is limp with his back to the door in the next shot. (00:11:00)
Continuity mistake: When Ice Cube is running out from jail, he kicks out the ventilator and climbs up the roof. Next shot from far, the ventilator is in its place. (00:11:10)
Continuity mistake: When Ice Cube climbs from the ventilator slot, the light changes between shots. (00:11:50)
Continuity mistake: After for some incredibly silly reason the sniper does not shoot Darius thus ending the movie early, the convict jumps off the roof and finds more guards to beat up. He faces the first one, punches him, a new one joins...only, not, since the next shot is of Ice Cube kicking some more the first, while the second is just now coming out of the door giving him more time to kick more butt. (00:12:20)
Continuity mistake: When Ice Cube fights three guards on the rooftop, the light varies significantly; just look at the guards when they are on the ground, the first one in particular, and where the shadow of the building extends. (00:12:40)
Continuity mistake: For his escape, Ice Cube leaps on the incoming surprise silent chopper. The trajectory of his leap is different in the various shots - he was never gonna be able to grab the skid the way he was falling in the first shots. (00:12:45)
Continuity mistake: When Darius is hanging on the helicopter, the way he holds it changes in between shots. (00:12:50)
Continuity mistake: When Ice Cube reverses the Gibbons' "Three strikes" speech, the waitress behind him keeps changing position throughout the scene, serving the table to the right of the door, or to the left, back and forth. (00:14:40)
Continuity mistake: After the prison break they are in a burger bar - Stone gets up empty handed and tells the other 2 how many laws they have just broken. When he finishes he drinks from a milkshake that has suddenly appeared in his hand. (00:15:00)
Continuity mistake: When Gibbons asks Agent Toby Lee Shavers to fit the rocket he picked from the car into a personal weapon, Michael Roof holds the rocket in two different ways (grip on the pipe or between the fins) depending on the camera angle. (00:20:10)
Continuity mistake: In a problem already spotted in the previous movie of the saga, the departed Michael Roof had poor ring discipline; when the scene of the assault at the barn begins and he reminds 'X' that it's a covert operation, he's holding the binoculars with ring-free hands, but in the shot when he sighs saying "Subtle..." he sports an obvious metal band (exactly like in the original movie) at his right ring finger. (00:20:40)
Continuity mistake: XXX aims the RPG above the fence, but when we see the shot being fired, the pipe is between two boards of the fence. (00:20:50)
Continuity mistake: When XXX stuns with rather unorthodox techniques the two guys the idiot co-protagonist left alone to guard the base, the first one to go down collapses with his right arm straight in front and the left hand below his elbow. When Scott Speedman gets back and start chasing Ice Cube, you can see the same man on the floor, right arm all the way down along his side, and his body turned so the left hand is not in the same position. (00:21:40 - 00:22:20)
Continuity mistake: When we see Ice Cube move from boat to boat cutting the fuel line, we see also the disconnected pipes flopping down. But in close-up the little fuel tube we see pumping gas letting it pool into the deck is carefully propped to stays up and spurts at full force. Darius did not take time to fix any engine that way, though. (00:23:30)
Continuity mistake: As Ice Cube waltzes into the truck after the boat stunt, Shavers stares at him. Behind him you can see the car window is half/a third of the way up. With all the commotion, it's unlikely that Shavers decided to close it a bit; it was practically all the way down before, when Darius told him to get his butt off the driver's position, and up when he was saying there was a problem. (00:24:50 - 00:25:20)
Continuity mistake: When Ice Cube jumps off the speedboat he crashed on top of the bridge, the natural light in the shot when he is walking towards the explosion without looking is quite different from the crash shots. (00:25:05)
Continuity mistake: With a gun pointed at his head, Gibbons retorts that General George Deckert does not seem to do "any of the dying." Look at the shadows on the doorframe, and look at them again when the camera is back on Samuel Jackson; big change even if he surely didn't go anywhere. (00:29:40)
Continuity mistake: After the funeral, Charlie is walking in a mall. Behind her there's a man with a maroon tie chatting with a woman at his side. He carries a beige coat that in the second shot is held differently, showing its black interior. (00:34:00)
Continuity mistake: Darius is making his way through the party crowd after the former SEAL member spotted him. Look when he drinks the last glass of champagne; in the background there's the same woman with a pearl necklace his pursuers already passed by. It's like they are -ahead - of him and not behind. (00:39:15)
Answer: To break the surface of the water making an easier penetration. Hitting water at high speeds can be like hitting concrete. By stirring up the water it "softens" the impact.
