Continuity mistake: When Franks Audi does the big jump from the top of the car park, it lands and you can see the front of the car get damaged, yet in later shots the damage has gone.
Continuity mistake: The Audi car is missing its W12 logo in the grill in one shot. In different scenes with the Audi, there are two different number plates at the front (at least where the number plate were supposed to be: one with two "holes" at the lower end, and one without. Obvious that there were 2 different cars used.
Continuity mistake: When Lola is in Frank's car, in the garage she doesn't have her seat belt on in the close-up. Then in two following shots she has her seat belt on. In the next following close-up, the seatbelt is off once again before she is seen putting it on.
Deliberate mistake: When Frank is fighting in the doctors surgery, both he and one of his attackers easily get thrown through walls, yet Lola's shots later don't penetrate to hit Frank when he's hiding in the storage cupboard.
Revealing mistake: When Frank is pushing Gianni out of the sinking plane at the end of the movie, the surface of the water can be seen, along with the reflection of Gianni's head on it. Since they are supposed to be pretty deep, this can only mean they're in a water tank.
Continuity mistake: When Frank picks up Jack at the beginning of the movie, Jack is seen leaving the school. Right before the shot, where the kids touch Franks car, Jack is carrying his schoolbag over his right shoulder. When he opens the car door, he is carrying it on both shoulders.
Factual error: After crashing headfirst into the water, the airplane is not damaged "correctly" at the end of the movie. The front shows little damage, when it should be crushed and the back has come apart, despite taking the least amount of impact from the hit.
Other mistake: When Frank shows up at Audrey's house, the cops are patrolling the grounds for security reasons. One cop sees that a glass pane in the french door has been smashed, to allow an intruder to unlock the door from the inside. But when the cop opens the door, we see that there is no lock, or even a latch, on the door.
Revealing mistake: Near the end of the movie, the car is driving up to the business aircraft as it is taking off. In one of the flashes of the aircraft, the engine reverse thrusters are engaged. This only occurs on landing. They must have filmed the scene in both takeoff and landing phases of flight, only intending it to look like the plane was taking off.
Factual error: The Audi A8 that Frank drives is supposed to be an A8L Quattro W12, but the W12 has long, narrow almost flat exhaust pipes, whereas Frank's W12 had smaller round tailpipes, and is missing certain badging on the trunk lid, suggesting it is actually a lesser model, maybe a 4.2 V8 Quattro.
Continuity mistake: Dimitri gets angry at Sonavitch and strikes him across the nose, cutting Sonavitch, and causes him to bleed. The blood only stays on his face, with none of the blood getting on that white lab coat he is wearing. Eventually Frank shows up and throws a knife, which he picks up from a table, into Sonavitch's left leg, as Sonavitch is trying to flee. All of a sudden there is blood on the white lab coat.
Continuity mistake: Frank and Jack arrive at Audrey's house and Lola enters the Audi. She opens the window and uses her guns. In the following shots the window is sometimes open, sometimes closed.
Revealing mistake: When Lola shoots the police helicopter, it is a noticeably poor visual effects job: the flames appear to merely be superimposed onto the helicopter, and it doesn't look as if the helicopter actually exploded.
Continuity mistake: When Lola kills the receptionist and doctor at the office, you can quickly see her bullets hit the window behind the doctor (at the end of the hallway) cracking the window up. Yet, in the next scene, when Frank is walking around, the window is not damaged at all.
Continuity mistake: When Frank does the big jump from the car park roof and lands, the bomb under the car should have been torn off.
Continuity mistake: At the doctor's office, Lola shoots up a police car, damaging the passenger doors, and destroying the light bar on top, then steals the car. When arriving at Audrey's house, to get into Frank's car and kidnap the kid, the police car she is driving has an intact light bar on top. When Frank leaves the driveway, and accelerates away, the police car is hit, but once again the light bar is shot up, and there are bullet holes in the passenger side doors.
Factual error: When the plane crashes into the water, both men in it should have flown towards the front of plane due to the sudden deceleration.
