Continuity mistake: The number and position of bullet holes in the police cars are constantly changing between shots. This is not because the gunmen are shooting at them constantly, some instances are between instant cuts. (00:44:00)
Continuity mistake: When the bank employee is talking to his boss in the carpark, the folder he has under his arm switches position instantly. Note the header. (00:12:30)
Visible crew/equipment: When Henry gets out the back of the police car at the domestic disturbance call, a crew member is reflected in the paintwork. (00:20:40)
Visible crew/equipment: When we see the dog walker getting loaded into the ambulance, there are green and red T markers visible on the floor. (01:15:30)
Continuity mistake: When Swat arrests Emil, the one officer has his foot on Emil's back. Camera changes to a higher overhead shot and his foot has gone from Emil's back. (01:13:30)
Continuity mistake: The truck driver flips two kills switches in his truck before running off. However when Emil tries to start the truck the switches are back in the on position. (01:10:10)
Continuity mistake: When Larry commits suicide his hand falls and comes to a rest on the grass. When the camera changes his hand is now on the kerb stones. (01:07:50)
Visible crew/equipment: When loading all the semi-automatic weapons into the cop car, the camera moves in and the filming equipment is reflected in the paintwork. (01:02:50)
Continuity mistake: When racing to the bank the registration of the lead swat car changes from "999015" to "853417". (00:30:00 - 00:59:20)
Continuity mistake: When Henry is down after being shot, the blood pools by him are constantly changing size. (00:46:50)
Revealing mistake: When Henry is running to the injured civilian there is a shot where you can see his kneepad under his trousers. (00:46:20)
Continuity mistake: Larry passes Emil the pill bottle with the lid on. However when Emil looks at the bottle the lid is off. (00:14:40)
Factual error: There are a few instances where a modern Bank of America flag is shown. This logo wasn't in use until 1998. The movie is set in 1997. (00:11:20)
Continuity mistake: At the very start the layout of the paper over the diamond window in the neighbours door changes position. Note the one top piece has a corner sticking out very noticeably that disappears in the next shot. (00:01:50)
Visible crew/equipment: When Henry is being loaded into the ambulance, and his partner walks over to him, a red marker is visible on the floor where she stops. (01:14:45)
Continuity mistake: When Emil is captured at the end, between overhead shots his arm goes from tucked under him to out by his side. (01:13:15)
Visible crew/equipment: When the cop gets out of the car to take the homeless man's trolley, a boom mic is reflected in the window. (01:08:50)
Other mistake: When Emil gets out of the car before seeing Larry is dead, he is shown in the front of the car on the right hand side of the car. But the car is a left hand drive as shown when he gets back in. Who was driving? (01:08:20)
Suggested correction: You see him sitting on the right hand side the whole time, even when he first gets in and Larry says "new plan." He's reaching over with his left hand to steer as the car moves slowly through the streets. There's even a straight on shot around 1:03:15 and it's not a flipped shot since the license plate is normal. It could just be moving on its own momentum while in drive, or he's reached over with his foot, or both sides have pedals (like on a driver's ed car).
Continuity mistake: Emil sticks his head into the pickup truck to inspect it. However the damage that is to the windscreen inside the truck differs to the damage on the outside. (01:09:40)
Continuity mistake: When Emil commanders the pickup truck the driver leaves the door open. When Emil gets out his car, the door is closed. (01:09:30)
