Character mistake: When Charlie is calling out the brick count to Napster from the subway, he describes it as being "13 across, 4 high, 4 deep". The bricks appear to be 2 deep in the safe (13x4x2), so he could just be lumping two shelves together, which works (13x4x4 = 13x4x2x2). The problem is that when the camera pans down there are 3 shelves in the safe. This means that there are more than the 208 bricks that Napster announces.
Revealing mistake: In the chase scene in the subway, Napster stops the subway train at the end of the tunnel to block the tunnel entrance. When you see the view on his laptop, the train station CLEARLY has a metal railing. There is no such railing throughout the rest of the scene. (Yes, it's likely while filming that railing was removed to enhance the scene then put back.)
Continuity mistake: In the sequence where the three Minis are being driven around a waterway as a rehearsal for the job, the auxiliary driving lights (the ones fixed in front of the radiator) go off and on. In the first shot all the cars have these lights on, in the next external shot the white car has them switched off, then back on again for the immediately following shot. Shortly afterwards the red Mini has these lights off for one shot - then back on in the very next one.
Continuity mistake: In the scene where "the Napster" is changing the street lights, there is a shot where armored truck 128 is slowly moving behind a grey or white Saturn (right after you hear on the radio "Truck 128, what is your progress?"). In the next shot, where one of the men in the truck says "Ah, get us outta here," you see Napster's computer. On the computer, when you see the street camera looking down onto truck 128, the Saturn is gone and all the surrounding traffic has moved. Truck 128 is one lane closer to the curb, and the car and SUV that were on 128's right in the live shot appear to be to the truck's left on camera. Other cars are gone or have changed places as well.
Factual error: The crew sets off explosives so the armored truck will fall through the street into the subway tunnel. In reality, the subway tunnels underneath Hollywood Blvd are about 6 stories underground. That means the truck would have to fall through approximately 80 feet of concrete, soil, rock and more concrete to fall into the tunnel.
Continuity mistake: During the Venice water chase, Charlie's boat goes under a bridge toward two green tugs. The tugs are moving apart to let him through, but when he comes out from under the bridge, the two tugs are close together and off to one side. In the very next shot, they are far enough apart to allow Charlie's pursuer to pass between them.
Continuity mistake: As you watch the chase scene after the golf course, you can tell that Left ear is driving the white mini instead of Handsome Rob. [If you watch the deleted scenes, it shows them switching places due to a gunshot wound in Rob's arm. A mistake, but explained.]
Continuity mistake: When we are looking back to when Charlie was a kid we see the thug kid walking by some kids before he slaps the book out of the other kid's hands. When it cuts, one of the girls that the thug just passed by suddenly is far down the hall. She couldn't have gotten there that fast.
Continuity mistake: Charlize Theron parks her original Mini in a tight spot behind the Ford 4WD where she goes in front first at a fair speed. But when we see the wide shot of the Mini parked in there, it's almost bumper to bumper - there is no way anyone could have parked the Mini in that spot going in front first no matter how small the Mini is.
Factual error: In the scene where Charlie is introducing the gang to Stella, the Napster arrives on a yellow Ducati motorcycle. All Ducatis are twin cylinder machines which have a distinctive throbbing exhaust note. The sound used is from a higher revving four cylinder machine, definitely not the bike being ridden. The same is true of the motorcycle chase scenes - they are BMWs, opposed twin configuration not producing the 4-cylinder engine noise, which must be overdubbed.
Factual error: In the Mini Cooper subway scene, the cars are first seen outside of the Hollywood/Highland red line station. However, when they jump in front of the metro rail line, it is the blue line they are jumping in front of and not the red line. The only red line station that meets up with the blue line is the 7th Street/Metro station, not the Hollywood/Highland station.
Revealing mistake: In the shots of the Metro tunnels, the "rails" are flush with the concrete surface, as streetcar tracks would be, to form a level surface that automobiles can easily drive on. In a dedicated right-of-way, however, the engineers would not go to this unnecessary trouble and expense; the rails would simply be mounted on the tunnel floor. Also notable is the presence of crossovers, but the absence of any movable switching equipment, rendering them useless.
Other mistake: In the opening boat chase in Venice, the safe is supposedly represented by a metal pipe structure covered by cloth. But it doesn't flap or wave in the wind at all. On the contrary it has completely straight sides. It is quite clear that there must be a box underneath.

Continuity mistake: After the minis jump out of the tunnel, Handsome Rob spins the mini around and tells Left Ear to open the door. The camera then switches to an exterior shot of the car and you can see that the rear window on the passenger side has been shattered. But in the next shot and throughout the rest of the film, the window is intact.
Other mistake: Just as the minis are finishing loading up the gold from the truck, there is a shot of at least 40 gold bars still left in the truck (3 rows of 13 bricks and at least 1 single brick on top. We are given the numbers by Charlie as he relays it to Lyle to work out the value). Then 10 seconds later, we are shown the minis leaving, having got all the bricks, packed up and started the engines. There is no way they could move 40 bricks and pack up in less than 10 seconds.

Continuity mistake: When Charlie and Stella are talking in Stella's hotel room in Hollywood, a strand of her hair goes from over her head to hanging beside her face as the shot cuts to behind her. When it cuts to her face, the strand is over her head again, though she didn't touch her hair.
Other mistake: When Charlize Theron is in her hotel room, Mark Wahlberg knocks on the door and walks right in without either waiting for her to open the door and without a key (or lockpick) apparent in his hand. Most, if not all hotel room doors lock automatically and cannot be left unlocked. Even the best lockpicker would take a few seconds to get it open.
