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. (01:46:20)
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. (00:19:45)
Visible crew/equipment: When Xander is jumping from the plane with the snowboard attached to his feet he does some aerial moves. When he is finished and about to pull his parachute cord you get a shot from up above. On the ground you can see the shadow of the helicopter that is there to film the aerial shots of the scene.
Continuity mistake: When XXX first gets on top of the AHAB submarine, he lands on it with a smash and you can clearly see his arm hitting the bubble covering the harddrive, which then is very loose and even opens up for a few centimeters. Next shot we see XXX opening up the bubble by releasing some security handles.
Continuity mistake: At the end of the movie where Xander's tanning at Bora Bora, notice that his tattoos are brighter. They have a just re-applied look.
Audio problem: In the mountain battle scene when Xander is in the airplane, he says: "Get me along that tower." His lips don't match with what he says, indicating this line was added during post-production.
Factual error: When Xander is snowboarding down the mountain, trying to outrun the avalanche, he is also at one point being chased by the gang on snowmobiles. According to the USSA World Speed Trials at Boonville, NY, the top clocked speed for a Ski-Doo down hill was 127.3mph, and in Marienville, PA, the fastest time for a Ski-Doo on a straight half-mile oval track was 87.0mph. However, the fastest recorded skiing speed was at The Super G Alpine Ski Competition, which was 85mph (men). Therefore, it would have been impossible for Xander to outrun an avalanche, practically with ease, yet have it catch up to the gang on snowmobiles in minutes, even seconds.
Factual error: In the beginning of the movie where Xander Cage (Vin Diesel) takes the senator's automatic transmission Corvette, he hops in and immediately pulls the shifter as far back as it will go. The shift pattern goes P R N D 3 2 1. If you pull the shifter as far back as it will go you would be in first gear going forward, but he lit up the tires in reverse. It's definitely an automatic - in slow motion you can see there are only two pedals. (00:06:15)
Continuity mistake: During the test when they infiltrate the drug lord's camp and X escapes. In one scene before he leaves the barn/building to go outside and get the bike you see him get up and lean against the door twice. Once to get up and look outside to see one of the copters blow up a truck then it cuts to a reverse angle and you see him get up again to lean against the door.
Factual error: When Xander uses the x-ray binoculars, it is impossible for that to work. First it would have to have every single bit of each layer of what he is looking at pre-programmed in it, or it would have to determine what to see through and what to be able to see. (00:44:45)
Continuity mistake: After the Prague cop shoots at Vin Diesel and Yorgi, when they are in the garage, they chase him in the GTO. You see Diesel skid the car to a stop to shoot the cop, but when the camera pulls away, you see the car skid another couple of inches after it had clearly stopped before. (00:49:35)
Factual error: When X uses the tray to "skateboard" down on the rails of the stairs, how could that tray possibly take his weight? The tray would have either bent in half or snapped in half and would have had X fall crotch first onto the railing.
Continuity mistake: In the beginning, when Xander steals the corvette, he goes into a reverse 180. When the camera angle is switched to camera 2, he's clearly coming out of a power slide (i.e. fishtail). (00:06:20)
