Continuity mistake: When Axel, Taggart and Rosewood show up at Emperian Fields, they are driving a brown car, but when they drive to Dent's oil fields, they are driving a blue car.
Factual error: Ronnie Cox is shot in the heart at point blank range by Brigitte Neilsen, and it looks to me like she's using a large caliber handgun. Keeping track of the action of the film tells us that Cox is sitting up in bed chatting to his friends just three days later. What nonsense. Even if he did survive (unlikely) he'd still be in Post-Op Intensive Care at that stage. He wouldn't be conscious, let alone allowed visitors.
Continuity mistake: In the opening scene, Eddie Murphy actually drives two different types of Ferrari - a 308 and a 328. During his journey, the cars keep changing.
Continuity mistake: Bogomil is standing and looking down into the engine of Karla's car when the assassin drives up. However when the shot is fired, Bogomil rolls on the bonnet of the car. When was the bonnet closed?
Continuity mistake: When Axel walks away from the receptionist in the Shooting Club with the bag of vitamins, in the close up he has his left hand below the bag, and holds the top with his right hand. But in the next shot he's suddenly let go with his left hand and only holds it from below with his right.
Continuity mistake: When Bogomil stops to help Karla, the driver's window in his car is slightly open. When he lies shot on the ground, it is all the way down.
Continuity mistake: Hugh Heffner disappears. In one clip he is right next to Axel. Three to four seconds later he is nowhere to be seen, even though the camera pans around, and the spot is quite crowded.
Suggested correction: After he tells them they need to leave, he's off camera for long enough to walk away. When the camera pans around, it doesn't show the area he would have walked away towards.
Continuity mistake: The speed with which the cement truck's mixing barrel turns changes significantly between clips of the car chase - and in some clips it doesn't turn at all.
Continuity mistake: When Axel breaks into the Shooting Club he places a piece of gum on the door. He squeezes it flat with his finger. But in the next clips, the piece of gum is not flat - and its position has changed.
Visible crew/equipment: When Axel is at the hospital and walks into Bogomil's room to say hi to Jan, the reflection of the moving overhead boom mic is visible on the glass surface behind him.
Continuity mistake: When Taggart is shouting at Axel in the pool he has his glasses on. In the next shot of him slipping into the pool, his glasses are gone. Also his cigar was in his hand in the scene before he slipped. Once he slips the cigar is in his mouth.
Continuity mistake: Following the final showdown, the bad guy is shot while trying to run Axel over. The car then crashes through a wall and a fence and plunges down a bank landing on its nose/bonnet. When it explodes, it is lying on its side.
Continuity mistake: When Axel is in Bogomil's house he finds his trainers. Axel picks picks up a left-footed trainer, but in the next shot he's holding a right-footed trainer.
Continuity mistake: The two $10 bills Axel gets from the gun club receptionist get very wrinkled when Axel squeezes them. But when he walks away, holding the bills up, they are totally straight.
Continuity mistake: When Axel, Rosewood, and Taggart are racing to to get to the City Deposit, Rosewood runs over several parking meters on the sidewalk which heavily damages the front end of the car. However, later when Taggart catches up to Axel and Rosewood outside the Playboy Mansion, he's driving the exact same car, complete with the police light, but the front end isn't damaged at all.
Continuity mistake: The construction worker Axel talks to at the beginning yanks off his hat (when he says "Son of a..."), but it jumps back to his head after the angle changes.
Continuity mistake: When Axel's knife breaks in the drawer in the Shooting Club, you can see that there is about 2 inches left of the blade. But when he holds up the knife there is only about 1 inch. Clearly not the same knife.
Continuity mistake: When Axel is hunted in the garage by the black car backing up, you see the hole in it's back window. One shot later the hole is more than twice the size.
Continuity mistake: When Bogomil stops to help Karla their cars are several meters apart. When Bogomil gets the first shot he rolls on the bonnet of Karla's car. He walks 1-1½ steps towards her. She pushes him back (i.e. towards her own car), but even so - he bumps into his own car. It was much further away and in a different direction.
Continuity mistake: When Chief Lutz is going through the case in the meeting with the mayor he says "There is no B and D." But there was a B - when Bogomil got shot. Didn't they find that letter?
