Continuity mistake: When Stella and Steve are on their date and Stella says "you're just gonna have to wait and see" you can see Steve holding his hand up. When it cuts to Steve his hand is down. (01:07:40)
Audio problem: When Skinny Pete warns Charlie over the phone, he says "mother freaking", which is a clear dub over. (01:15:30)
Character mistake: When the helicopter's pilot says "Zorro-Mike" it should be "Zulu-Mike" (01:20:15)
Continuity mistake: When Napster is comparing height of the armored trucks they all have their truck number on the fender right behind the rear tire, but the number isn't there in any other shots. (01:23:10)
Continuity mistake: When the three armored trucks are driving side by side there are stars on the sidewalk, indicating that they are behind the walk of fame. Truck 128 passes this and later, the Minis are seen on the Walk of fame with the truck passing beside them. (01:23:20)
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. (01:24:55)
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. (01:26:10 - 01:27:25)
Continuity mistake: When the Mini Coopers enter the subway tunnel, the white Mini is bumped by the train, yet in the following scene and the rest of the movie no body damage is visible to the rear of that Mini. (01:27:45)
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.) (01:27:45)
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. (01:29:15)
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. (01:33:40)
Continuity mistake: During the chase scene in the tunnel, the two motorcycles were always pretty close to each other through most of the scene. When the first motorist was knocked off, it should've taken out the second one right away. (01:36:00)
Visible crew/equipment: When the Mini Coopers jump out of the sewage tunnel, you can see the black ramp they launch off of to give the tunnel exit more of a dramatic effect. (01:36:15)
Factual error: Even a minor low-speed impact of a motorbike that heavy into a car door would damage it so badly that it would look different than shown on the white Mini - if the door were still there. Most certainly the glass would be shattered and the door could not be closed. (01:36:30)
Continuity mistake: When the blue Mini is driving through the streets, there is a dent on the rear wing on the passenger side, but when you see the car drive into the train, the dent is no longer there. (01:37:00)
Audio problem: When Mashkov's men grab Steve, you can hear him say "Come on, Charlie", but his lips aren't moving at all. (01:39:35)
Revealing mistake: As Edward Norton is finishing up the chase scene to the train station, the last turn he takes is off a one way street. But as you watch the other cars, you notice all the cars are going the wrong way down the one way street. Except for Norton that is. (01:40:35)
Factual error: When Mark Wahlberg is a child, he steals a wallet with bills sticking out. The bills are large head print, not possible in that time period. (02:10:10)
Continuity mistake: In the getaway scene after Charlie leaves Stella and Handsome Rob to go after Steve, Napster says take the next left and you see the Mini's number plate which reads 2SBI658. When he skids narrowly missing a truck it now reads 2SAQ321.
Revealing mistake: When Edward Norton takes Charlize Theron out to dinner, the mustache on the right side of his mouth is further away from his lip, than on the left side of his mouth showing that the mustache is only stuck on.
Answer: The Mini Cooper for the movie was also made as an electric car for the chase scenes in the tunnel because gas-powered cars were not allowed to be used in the tunnels. I heard that from the director's cut.
