Continuity mistake: When the police arrive at Victor's house the guards in the security room decide to run. At this time they are wearing guns in shoulder holsters. When you see them next, running out the door, they are unarmed. You see them again in the van, again with guns and shoulder-holsters.
Continuity mistake: Check out the police car(s) when Axel is in the back of the trailer truck. At first, the police arrive in a then-new 1984 Plymouth Gran Fury, then when the truck flees, the police car reverses back out of the alley, emerging in the next shot as a late 1970's Dodge St.Regis. The next shot has the police car now a 1977 Plymouth Fury, which seconds later changes back again to the St.Regis.
Revealing mistake: Just before the white Beetle is struck by the truck, it can be seen moving forward as if being driven, but there is nobody in it, and its tires do no touch the ground as if it is on casters being pushed by the green Buick (with black vinyl top) behind it. A tubular brace that might connect the Beetle to the Buick falls off the Beetle's right-side rocker panel when the car is hit.
Revealing mistake: Near the start of the truck chase, a long shot shows the truck followed by several police cars. In the foreground, another police car's roof comes into view, showing hastily-applied orange numbers on the roof. They appear to be magnetic vinyl, but don't adhere well at all, looking very wavy, with gaps under them. Also, they seem to be applied over faded, yellow, painted, *different* numbers, and are aligned so badly, that the old numbers are very exposed. This error is visible in later shots as well, but most exposed here.
Continuity mistake: In the last scene (Victor Maitland's house) Taggart, Rosewood and Foley are hiding behind a small wall. After Rosewood says 'I hate machine guns', all three of them shoot back at the gangster, who is trying to gun them down. Foley shoots first, one shot and his gun is empty. One second later he shoots back once more (with the empty gun), and he reloads only after this.
Deliberate mistake: When the truck is slamming numerous parked cars on a residential street, it sideswipes a parked Dodge Aspen (white with tan landau top). At the lower-right corner of this shot, a white Chevy Nova is parked at the corner (its vinyl top and trim has been poorly painted the same white as the body). Both these cars are repositioned to be at the roadblock location at the end of the chase, with the Nova slammed from behind by the truck and the Aspen parked near the cop cars.
Continuity mistake: When a police car pulls in front of the truck from a side-street, a shot from inside the truck's cab just before the two collide shows the police car's license plate reads '742JOU', its unit number (on the C-pillar) is '82340', and its trunk lock cylinder is missing. As the car spins out with its rear toward a camera, the plate now reads '103DLS', the unit number becomes '82199' and the lock cylinder is back.
Continuity mistake: When Victor catches Axel and Jenny at the warehouse one of Victor's henchmen is holding a gun to Axel's head and his other hand has Axel's sweatshirt in his grasp. Watch the hand holding the sweatshirt, it keeps changing positions as the camera angle changes throughout the scene.
Continuity mistake: During the machine gun fire at Victor's house Rosewood holds up his badge and says "Police, you are all under arrest". The bad guys then shoot at Rosewood and Taggart. They shoot up a sculpture/planter above Taggart. A piece falls onto Taggart with part of it leaning against the planter and the top part leaning against Taggart's shoulder. The next shot the piece is shown standing on the ground leaning up against Taggart's head. It did not have time to relocate to the position it ended up in.
Continuity mistake: When Axel is asking Lt. Bogomil to straighten things out with Inspector Todd during the conversation we get numerous shots from behind Foley's head. When he says "I guess I'm just out of a job. It's cool though" there is nothing in his afro. The camera then goes to Lt. Bogomil. After Foley tells him he is going to "start his own investigation company. How does that sound?" we get another shot of the back of his head. There is now a white piece of fuzz on the back left side of Axel's afro.
Visible crew/equipment: When the fruit truck is slammed by the tractor trailer, it slides into a parked, green Chevy Impala. Before the collision, the Chevy can be seen to have camera equipment under its front and rear bumpers, concealed by black cloth or tarp (the rear camera location is made obvious in a slow-motion shot when the fruit truck slides right toward we viewers). When the Chevy is hit, the rear camera is hidden from view and very likely damaged, but we actually see the front camera fall over.
Continuity mistake: When Axel and Mikey are in the pool hall, the guy playing pool calls out a 2 rail bank. Mikey says "fifty bucks you don't make that shot". The guy says "bullshit". They they get a close up camera shot of the shot. The cue ball and the angle of the shot change between the bet and the actual bank shot taken. At first the cue ball was down near the corner. When the shot is taken the cue ball is struck from around the side pocket.
Factual error: When Axel and Taggart are taken under fire by the gunner with the dark glasses (who is shot by Billy), notice that the gunner stands perpendicular (i.e. at a 90° angle) to the stairs where Axel and Taggart take cover. Yet, two of the bullet holes appear in a column at the base of the stairs which would have come from a different trajectory, namely in line with the stairway and thus from Axel and Taggart's flank.
Visible crew/equipment: When Axel first pulls up to the country club to talk to Victor, he gives the valet his keys and requests his car be "parked in a good spot" as last time it was damaged. As valet drives off you can see the reflection of the camera, stage light and a crew member on the rolled up window. Easier to see on the VHS version.
Continuity mistake: When Axel visits Victor at the club he throws Victor's henchman across the buffet table. When the henchman gets up he has a strawberry smashed into his hair at the top middle-right portion of his forehead. Later on the strawberry is gone but there are green leaves that now are on the middle-left side of his forehead. This is evident as the camera regains focus although the colors can be seen when the the view of him is blurry.
Continuity mistake: When Axel and Jenny go to Victor's warehouse you see Axel walk up to a crate and put both of his hands on it. The camera angle changes and his hands are no longer on the crate and he's pointing to a label on the crate telling Jenny that this is what they are looking for.
Continuity mistake: Right before Axel shoots Zack at the mansion, there is a large vase behind Axel. When he shoots Zack however, the vase disappears. There are bullet holes in the wall where the vase was, implying Zack fired his gun at Axel. But Zack never fires his gun, so the vase simply vanishes from the scene.
Continuity mistake: At the end shoot out in the house, Foley and Taggart bump into each other and a henchman shoots the grass near them with a submachine gun, ripping up the grass. Billy shoots the assailant and they come out from behind the wall - the grass that was shot up is in pristine condition, with no bullet holes or damage whatsoever.
Continuity mistake: When Axel Foley hits Victor's hitman in the restaurant and the hitman lands on the buffet table, he has lots of stuff on his face and something green is stuck on his forehead. In the next shot, the hitman's face has been cleaned up a little and the green thing stuck on his forehead disappears.
