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.
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.
Revealing mistake: A rocket launcher that XXX shoots is clearly a camcorder with bits added onto it. You can see the viewfinder from a side shot, and the lens from the front.
Revealing mistake: When the AHAB launched its missile in the underground lab, it shows a shot of one of the scientists laying on the ground dead. You can see him breathing.
Visible crew/equipment: Just after XXX says "There's the bridge" and points, you can see the boom mike on top of the frame.
Factual error: There are no mountains high enough near Prague. The closest mountains that fit the description are the Alps between Germany and Italy.
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.
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.
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: 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: 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.
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.
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.
Revealing mistake: At the end of the movie, Czech Air Force sends two Sukhoi 22's to destroy Ahab, armed with rocket pods. When shown from the front, you can see the rocket pods are empty.
Continuity mistake: After Xander's car jumps off the bridge, you can see in one shot that he is jumping from the car. In the following shot, Xander is opening his parachute and jumps off the car.
Factual error: When Xander is seeing through the binoculars what is happening in the basement, he is looking through a brick wall. He would not be able to hear them.
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).
Plot hole: When Xander Cage is just about to try and get into the basement, two scientists walk out. One of the scientists says 'We are finished now - what about you?' The other scientist replies 'We will be done tomorrow' - yet just a few scenes later Yorgi uses the rocket to gas the whole room of scientists. How were they supposed to finish off their job?
Factual error: When Xander is riding down the rooftop of the barn in Colombia, he lands perfectly smooth without a sound. Now with a jump of at least 10 feet and at that speed, the motorcycle would at least bounce a bit.
