Continuity mistake: When XXX has to take the second test, after he runs out of the shack where the insane guy is, he finds a dirt bike. The dirt bike changes colours 3 times.
Continuity mistake: When XXX steals the Corvette, we see he breaks one of the side view mirrors. On the following shot we can quickly see that one side view mirror is broken and the other one is not. Then when XXX starts talking we see that both mirrors are broken.
Continuity mistake: When XXX is snowboarding down the mountain in front of the avalanche his goggles change from round to rectangular back to round again. The snowboard also changes repeatedly - from red to blue - throughout the entire run. The tops and bottoms of the boards - when high or low angles are shown - are different for both boards, so you see 4 different colors.
Continuity mistake: When Ahab is launched, and XXX and Yelena are running, Yelena's singlet top changes from blue, to white, then back to blue again in different shots.
Continuity mistake: When Xander throws grenades to make an avalanche he unzips his coat. He fixes his goggles and jumps. In next scene his coat is already zipped up. Clearly he didn't have time to zip it.
Continuity mistake: When Triple X is brought to the diner, he has no jacket on. Later on in the plane, he's got a jacket on. When he's on that farm, the jacket is gone again, but when the raid is going on, he has got his jacket back. I don't know where he's always hiding his jacket, but it must be a really clever place to hide it.
Continuity mistake: When X ejects the roof of the car towards the end of the scene, you can see that there are no windows attached, however, after the roof is ejected, the windows of the car disappear.
Continuity mistake: When Xander is snowboarding down the mountain to take out the communications tower, he snowboards goofy (right foot in front) to regular (left foot in front) many times. That either means the stuntman is regular footed, or he would have to do a lot of 180's spins, which is impossible to do when there is a giant wave of snow chasing you.
Continuity mistake: When Xander is snowboarding down the mountain to take out the communications tower, there is one point where the avalanche clearly bumps Xander and moves him ahead by about 12 feet. It appears to be a correction in the graphics so that it doesn't appear that the avalanche will outrun him down the mountain, however, poorly edited.
Continuity mistake: When Yelena and X are on the roof of the building he's staying at and Yelena tells him "Remember what I said, after you kissed me? Never again. I lied.", the shot just before he kisses her she is wearing bright red lipstick, but the next shot it's clearly gone. Likely to spare X from red lipstick all over his face.
Continuity mistake: When Xander is chasing the sub, he is driving on a road to the left of the river, yet when he comes onto the bridge, the car does a left turn onto the bridge, which indicates that the car was driving down a road to the right of the river.
Continuity mistake: In the scene just after the senator calls the cops, you see XXX round a corner in the Corvette, look closely and you will see both mirrors still intact, but in the next scene, they are gone again.
Continuity mistake: When XXX arrives at Yorgi's mansion, there are girls in the water fountain out front. If you watch Yorgi's large bodyguard, the one that sports 5 or so earrings and a large beard, you will notice that he takes a girl out of the fountain. A split second later the shot changes onto XXX and in the background the large bodyguard is seen taking the same girl out of the fountain again.
Continuity mistake: When Xander is in the Diner you can see his watch three times. It shows a different time the first time you can see it than the second and third time.
Continuity mistake: When XXX is hanging by his arms in the shed, just before he tells the bad guy he is short, the bad guy is holding onto XXX's shirt. In the next shot of the bad guy, he is isn't holding the shirt, yet in the next shot of XXX, the bad guy's hand is holding the shirt as before.
Continuity mistake: When Xander Cage is hung up by his arms in the barn, he is hit by a man with his left hand holding a large knife in his right hand. When the man hits him again it is with his right hand, which should have the knife still in it, but it doesn't. There is no camera shot of the knife at all when the man hits Cage with his right hand, so where did it go?
Continuity mistake: The first time you see Samuel L. Jackson, his eye on the burnt side is a real pale brown, but throughout the movie his eye changes to a normal brown and then light, then back to dark.
Continuity mistake: When the Navigator is shot by the helicopters you see it fly up, but while the ugly dude is in it. But when Xander drives off it to get over the Cocaine shack you can obviously can tell that he is not in the car.
Continuity mistake: In the opening scene at the rave, Yorgi instructs Kirill to shoot the man in the suit. In the initial shot of Yorgi telling him, Kirill puts the cigarette behind his ear. In the following shot, he puts it there again.
