Continuity mistake: Just as Mike saves Marcus from being hit by the taxi, there is a blue bumper attached / missing / attached / missing from the taxi. (01:37:05)
Continuity mistake: Mike and Marcus go to meet Sanchez and Ruiz on the steps, Sanchez is sat down holding a doughnut (or something) in his right hand and a coffee in his left. A few seconds later, when talking about bongos, there's a close up shot and the items change hands. Back to a wide shot when Mike and Marcus enter they switch back. (01:37:17)
Revealing mistake: When the computer is being hacked and the password and/or code for the database is shown on the screen, most of the display is for an Autodesk printer driver. (01:39:00)
Visible crew/equipment: At the end of the car chase scene between the Porsche and the AC Cobra on the runway, a shadow of the camera as well as the boom can be seen just as the Porsche drives between the concrete blocks. This can be seen at normal speed but is best viewed in slow motion. (01:46:00)
Other mistake: At the very end of the movie Mike has the bad guy down on the ground and he's got his gun in the guys face, we see a shot looking straight up the gun barrel with Smith's eyes over the top of it. If you look at the barrel of the weapon there is a little point of light at the back of the barrel. This is caused by sunlight shining through the firing pin hole in the back of the chamber showing that the gun has no round in the chamber. (01:46:50)
Continuity mistake: After Mike has killed the bad guy at the end, the distance of the bad guy's hand from the gun changes instantly. (01:48:30)
Plot hole: Why was $100,000,000 worth of heroin sitting in the police vault all this time before the bad guys stole it? Wouldn't the DEA have taken possession of the drugs long before that?
Continuity mistake: When Marcus Burnett drops Julie Mott off at Mike Lowery's apartment it's dark outside. When he leaves shortly after, there is daylight outside.
Continuity mistake: In the final car chase - in the close-ups - we see Marcus turning the steering wheel quite far from side to side. With the speed they are going that would make the car slalom severely - and probably go out of control. At that speed only very small movements of the steering wheel are necessary (and safe).
Audio problem: When Mike and Marcus are driving in Marcus's car, just before they sing Bad Boys, in the shot over Mike's shoulder we see that what he is saying does not match the movement of his mouth.
Continuity mistake: The kegs of ether in the truck have hazardous material labels applied to them. These are diamond shaped labels that indicate the class of material in the container. Throughout the chase scene they alternate between Flammable Liquid labels (solid red) and Flammable Solid labels (half red, half white).
Visible crew/equipment: When Marcus is driving and Mike is saying that he is driving slow enough to drive Miss Daisy, when the camera is facing them from the driver's side you can see where the camera is attached to the driver's door. [This may only be in the full frame version. In the wide-screen version, the frame doesn't show any of the door, just the top of the wing mirror.]
Audio problem: When the bad guys attack the main girl's house, one is heard to be pumping his shotgun between shots. The gun is a SPAS-12, and the pump-action is only used when firing non-lethal rounds; otherwise it fires semi-automatically.
Factual error: There is absolutely no way that Internal Affairs would have any authority or power to shut down an entire police force because of stolen drugs. As in the plot of the film, that type of decision would be decided by the city council on a vote and approved by the mayor. In any case, an extensive investigation would take place and the culprits would be arrested and prosecuted. No police force would be disbanded because of this absolutely fictional scenario.
Other mistake: In the film, Lawrence and Smith's characters are Narcotics detectives with Miami Dade Police. There's no way they should be at any homicide investigations. Narc and homicide are totally two different units within law enforcement, so it's unlikely narcotics units would be at a homicide scene. Being the scene where they're investigating Smith's friend getting killed, and then they stumble across the dead body at the mansion.
Suggested correction: The captain called Mike and Marcus to the scene to help because it appeared related to the missing drugs. They were there to find leads to the missing heroin.
Yes, that could be correct, but the chances of that happening are slim to none. A captain from Narcotics wouldn't even have authorization to call his detectives to a murder scene to help out homicide detectives working a murder. Any information or clues would be collected and shared with other units or agencies if deemed appropriate.
Continuity mistake: At the beginning of the film when Martin Lawrence is in bed with his wife, he wakes up on the left side of the bed and leans over turn the alarm off. The next shot he's on the right side of the bed and the alarm has moved to the right side too, he's reaching over to turn it off.
Continuity mistake: When Marcus and Mike are chasing the bad guys who have Julie, the sun changes between shots - while the bad guys are getting away in the cab, in the background you can see it's sunset, but in he next shot the sun is shining back again.
Other mistake: In the scene where Mike returns to his apartment for the first time since Julie was living there, as they walk towards the elevator Chet says "Hey Mr Lowrey" to Mike then says "Hey Mr Lowrey" to Marcus although Marcus never told him that he was taking Mike's identity.
