Continuity mistake: When Jack rips the door off the cab, he first breaks the top hinge and enters the cab. In the next shot when he pulls the cabbie out of the car, the door is completely off and laying on the ground. A few shots later when Jack grabs the newspaper, the door is seen hanging again. (01:40:10)
Continuity mistake: When they are in the ambulance, Danny screams 'I said, turn around!' and draws his gun. The next shot shows the driver looking to the rear and getting scared by the gun. In this shot you can see by the window that the car is totally stopped, and some car with a yellow light is passing by them. But in the very next shot, the ambulance is stopping (you can even hear the tires) and there is no car with the yellow light to be seen. (01:55:05)
Continuity mistake: When Nick tells Danny that he can arrange a preview of the movie, he puts his glasses on, yet from the side-angle they're off.
Continuity mistake: Jack's shirt does not have bullet holes, as he walks up the stairs on the way to his apartment, but in the previous scene his shirt had bullet holes, as he packed up his stuff from his desk. (01:03:20)
Continuity mistake: When Jack is speeding to get to the funeral at the hotel, he drives through the pond in front of the hotel. When the car goes in, it has the set of wheels it had throughout the film. When it emerges from the pond, it has a new set of white Cragers on it. (01:08:05)
Continuity mistake: When Whitney points the gun at Benedict, her arms change position between shots.
Continuity mistake: During the car chase when Danny is in movie-world, Jack is firing the thugs and his hair moves a lot during the wide angle, but barely at all a frame later in the close-up.
Continuity mistake: When Benedict pulls Leo's finger at the funeral to start the timer on the wristwatch, you can see that the timer was pre-set for ten minutes on the upper part of the display and the countdown is in the lower part of the display. There are two more shots of the countdown on the watch. First at 3:32 left when Jack knocks out the doctor and then at about 30 seconds left over the tar pits. Both of these shots show that a piece of silver tape has been applied to the upper half of the display, probably to cover a lower starting count so they wouldn't have to wait 10 minutes between shots. (01:07:50 - 01:18:05)
Continuity mistake: When Benedict is getting away from Jack's daughter's house he gets into a white car, but when Jack shoots him the car is black.
Suggested correction: It's the same car the whole time. The car he gets into is black, but the way the camera picks up the light that hits part of the door does fade out of the color some, but you can see the rest is black.
Continuity mistake: The chopper lights a bright laser light that reflects on Jack's forehead. When the crane behind appears, the light disappears, yet in the immediate close-up of Jack's face the beam reflection is still there.
Continuity mistake: When Danny's mom is asking him why he missed school, the purse's strap on the table behind changes positions between shots.
Continuity mistake: When Jack is being chased and the guys in the red pick up truck are throwing dynamite at him, they throw one that hits a parked car just as Jack makes a hard left turn. The next shot has the car exploding and Jack having made a hard right turn.
Continuity mistake: When Jack s shooting at the chopper from inside the elevator, its door has bits of remaining glass around the sides, which disappear from the chopper's POV. This changes back and forth.
Continuity mistake: When a prostitute walks to Benedict and opens her coat, when the angle changes her right arm and hand are in a different position, plus a guy is suddenly right behind her.
Continuity mistake: When Arnie's car is parked with the thugs in front, and he is pressing the gas pedal while Danny sits behind encouraging him, there's a wide angle of the car and Danny is completely gone, only to reappear in the next shot.
Continuity mistake: When Danny ties his mom's tie, her collar swaps from raised to lowered between shots.
Continuity mistake: When Vivaldi is interrogating Frank, the ropes around him are tied differently depending on the shot.
Continuity mistake: When Jack and Danny enter the video store a sign on the door reads Acme Video, yet inside there's a huge "Blockbuster Video" sign.
Continuity mistake: When Arnie drives towards the red truck, their distance to the boxes increases/decreases randomly with no logic whatsoever.
Continuity mistake: Jack is inside the elevator after the chopper has killed the mobsters. He's got glass all over him, but when the angle changes to a wide shot the bits of glass are gone.
