When Steve is driving the Bronco through the train yard, his mustache is missing.
After Stella has successfully opened the safe in the metro, the drill that was stuck in the safe's door after the glass cracked disappears.
When the three MINIs jump in front of the underground train
you can see the last MINI hit the front of the train with the rear bumper and the whole lot goes through the tunnel. But in the next shot Napster stops the train and it stops just in front of the tunnel to block it.
In the beginning when the crew drove into the water, they all would have died, the temperature of the water is so low, your heart and lungs would stop working.
And if the dive would not have killed them, they would die outside the water, with wet clothes and a temperature below zero.
The amount of blood in Steve's mouth after Charlie decks him in the café changes inconsistently between shots.
Bullets do not travel at full speed through water. In reality, all bullets slow rapidly as soon as they hit the water, contrary to what is seen when Steve shoots into the lake. Not only do bullets slow down quickly when fired into water, high powered bullets from weapons like the assault rife Steve is using actually shred within inches of the surface of the water and then simply settle to the bottom of (in this case) the lake. Oddly enough, high-powered bullets have less penetration through water than lower-powered ones (a bullet's power is determined by the cartridge charge).
It was stated earlier that brass would not be used in explosive applications and that gold is the best conductor. Actually gold is only the third best conductor. Copper is 33% more conductive than gold and Silver is 50% more conductive. Gold is used for critical contacts, not because it is a better conductor, but because it does not corrode. While brass is not an excellent conductor, it is 28% as conductive as copper and 40% as conductive as gold.
In the alps, the border-sign says 'AUSTRIA'. In Europe, the country's border-sign is always spelled in the language of that specific country at that location. At the Italian-Austrian border that would be German, not English. So the sign would say: 'Republik Österreich'
When Steve's cable is disconnected, static shows on his HDTVs. He would have had a black screen. Static would appear only on analog sets.
When Charlie tells Lyle how many bricks there are, Lyle tells Charlie 208. He asks Lyle how much that's worth, and Lyle (after making a mistake) says $27 million. However, at that time, regular (non-decorated with the dancers) bricks were worth about $168,000 each, which would make 208 bricks worth at least about $35 million.
Because the letters of the "Hollywood" sign are on a hill with an uneven, undulating surface, they're not all in the same plane. This means that from some angles it really does look as though the sign says "OHLLYWODO".
The weight of the gold recovered from the armored truck, valued at $27 million, would weigh around 4,500 pounds at the period price of gold. It is entirely possible to divide that among three (~1,500 lbs per car) highly modified MINI Coopers and move it around quickly. While it would make the cars quite tail heavy (they would land rear first, at quite an angle when jumped), it is not implausible to modify the suspension to handle the additional weight and increase power to achieve a reasonably quick degree of performance. In fact, we can hear that the MINI Stella drives features the distinctive whine of an Eaton M62 supercharger. The MINIs have a 63/27 F/R weight distribution out of the box. With 1,500 lbs of gold in the rear, the distribution would change to roughly 41/59 and the car would weigh just over two tons.
The wide shot of the driving range facing the "golfers" is not reversed; the numbers and letters are backwards because the signs are facing the street on the other side of the fence, and the camera is showing the back of those signs.
When the initial modification work is done on the minis, they are taken for a test drive. There are interior shots of Charlie, Rob, Stella and Left Ear driving but the exterior shots only have three cars.
When the MINIs exit the pipe during the escape from the underground at least one of the cars lands with its nose hitting the ground first while its tail is high in the air. Due to the weight of the gold in the back of the car, this would be physically impossible.
At the end of the movie, when Charlie Croker hands off the case of gold, he easily spins it around with one hand and lifts it off the ground very easily. Even if were only half full of gold, the case would not be that easy to lift.
The diver propulsion vehicles need a more or less neutral buoyancy to travel. To counteract the gold's weight, air-filled bladders of around 18 times the volume of gold would have been needed (gold has a density of 19.3 grams/cubic centimeter) but none are showing.
When the MINIs jump out of the tunnel, they all land on the front bumper, but in the next shot in the park, all the cars are undamaged.
When Steve is checking to see if his internet is out, the computer has no power cable plugged into it.
After emptying the armored car and during the chase, the three MINI Coopers leap out of the drainage pipe and land front first despite being rear-loaded with over 1,500 pounds of gold each.
After Wrench modifies the MINIs, he and Charlie are walking past a shelf filled with what Wrench describes as "unnecessary engine parts". On that shelf are three exhaust headers and three crankshafts (along with many other parts) which are absolutely necessary for an engine to run.
When all 3 cars exit the tunnel the white mini copper driven by Handsome Ron turns car around tells Left Ear to open his door. Once the door is opened the motorcycle hits the door tearing it off. The rest of the get away shows the door on the car.
The three MINIs' license plate numbers begin with a "2". This means they had to have been issued before 1989. The MINIs were later than this vintage.
When Steve is being dragged away by the Ukrainians you hear him plead "Come on Charlie!" but his mouth never moves.
When Skinny Pete says "Mother Freakin' Ukrainians" his mouth clearly says "Fucking".
The motorcycles used in the chase scene are BMWR1100RT's, which are 2 cylinder motorcycles. The engine noise heard from them is that of a 4 cylinder sport bike, a very different sound than a 2 cylinder sport-touring bike.
When Lyle arrives to the first meeting with Stella, he is riding a yellow Ducati 748 superbike. The engine note heard is of a generic inline-four cylinder sport bike, which sounds nothing like the Ducati desmo L-twin in the 748.
At 6:01 when Jason Statham starts the motor on the boat the sound it makes is that of an inboard engine (listen to the exhaust note) but the boat clearly has a 200hp Mercury outboard, which has a very different sound.
When the van carrying the gold falls down in the underground a chain "helping" it to fall is visible next the front wheels.
While Stella is driving to the train, you can briefly see the reflection on the driver side window of a cameraman sitting in the passenger seat.
In the beginning of the movie, when they navigate the boat backwards into the dock, immediately after Charlie says "we're in", the full camera crew can be seen in the reflection of the boat's window.
When Charlie's blue MINI jumps from the train platform onto the train lines, a pile of boxes designed to cushion the vehicle's impact can be clearly seen.
When Charlie is being chased by Steve in the helicopter, he pulls a 180 when he sees the truck blocking his way. When he starts up again and the shot shifts to ground level, you can see the reflection of the right front wheel in the safety shield that's in front of the door camera.
The train that Lyle remotely stops in the station is a Blue Line train. The Blue Line is a light rail line that runs from Downtown Los Angeles all the way to Long Beach. It doesn't go anywhere near Hollywood.
When John Bridger calls his daughter Stella at the beginning of the film, she is still in bed, and the light outside the window indicates early morning. She confirms this by saying, "Daddy, it's early". However, John calls her from Venice, Italy, at about 8:30 am local time. Assuming a 6-hour time difference to Philadelphia (where Stella is) this would make it 2:30 am her time. It is unlikely that any light would be visible at that time of the morning.
When the MINIs are going down the metro, in the Hollywood and Highland station, it's not really the Hollywood and Highland station, but in fact the 7th and Metro station, stationed in Downtown Los Angeles, based on the fact that the three cars jump into the tunnel in front of a Blue Line train.
Lyle basically confesses to the traffic mess in Los Angeles when he trolls the traffic center by displaying the "You'll Never Shut Down the Real Napster" message on its monitors. At the end of the film, he's shown on the cover of WIRED Magazine being profiled as the 'Real Napster'. Law enforcement would easily make the connection and come after him.
During the chase through the Los Angeles River Basin, police cars blocking traffic and officers calmly watching the chase can be seen on an overpass. They couldn't have been part of the chase as no one except the two gangs of thieves know what's going on at this point.
There is no way the boat used would be able to carry the weight of the safe and gold, and even if it didn't sink, it would handle extremely poorly. The chasers would immediately realise it was a decoy.
It's stated by Mashkov that "he will be on Train 59 to New Orleans." Train 59 is called "The City of New Orleans" and leaves directly from Chicago to New Orleans. It doesn't go anywhere near Los Angeles. The only train from LA to New Orleans is Train #2, the Sunset Limited.
