Continuity mistake: At the beginning of the movie, Eddie Murphy's character is trying out for the cop show. While arguing with the man trying out as chief, Eddie Murphy slams his hands on the table. When he does this, and throughout the scene, his gun holster and shoulder straps are clearly visible. But after he slams his hands down, and the camera cuts to the directors of the show and then back to Eddie, the holster is gone. The camera then cuts back to the directors and then to Eddie a second time, and the holster is back.
Visible crew/equipment: When the SUV gets blown up, in one quick shot you can see a cable pulling the car forward.
Continuity mistake: Robert De Niro and Eddie Murphy visit the crime scene where the house is demolished, and Eddie Murphy is sometimes seen through the recording video camera. The counter is first at the 55 minute mark, then changes to 21 minutes in the second shot, then 23 minutes less than a minute later, and finally the 26 minute mark approximately a minute later.
Continuity mistake: When the Corvette is chasing the garbage truck, the top is on and then seconds later the top is gone.
Continuity mistake: In the chase scene between Robert DeNiro (in the police cruiser) and the garbage truck, the windshield switches back and forth from being completely shot out to having a couple of holes in it, then being perfectly intact. Toward the end of the sequence it settles on having holes, since DeNiro has to kick it out in order to escape from the cruiser.
Continuity mistake: When the producers try to give Robert DeNiro the retired drug sniffing police dog, the dog is sniffing around in white powder in a potted plant, which leaves white stuff all over his snout. When Eddie Murphy tries to pet "Powder", we see the dog growl and snap at him with no trace of anything on his face. The next time we see him, the powder is back on his snout.
Visible crew/equipment: When Trey is driving down the alleyway after the truck, an inside shot is shown and visible in the window onside of the police car you can see at least 2 reflector screens the camera and the truck towing the car.
Continuity mistake: After they shoot the pool and the water starts to fall, it does not stop falling.
Visible crew/equipment: At the end when Mitch is getting dragged down on the floor about to go over the edge and Trey grabs him, the stuntman is visible.
Factual error: During the Weapon show Eddie Murphy is shot at by the bad guy with a big gun. He hides behind a pile of sand bags. At the end of the movie the same guy shoots into the ceiling, with the same gun, and we can see that the bullets go through the ceiling making huge holes. How is it possible that the bullets go through a ceiling made of concrete, but not through a row of sand bags?
Factual error: At the scene at the top floor of the apartment building, the roof gets shot about 5 times. There is a pool overhead. But the water takes about 45 seconds to start falling.
