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. (00:59:45)
Suggested correction: It's not in real time. They could have been back on a different occasion; we just aren't shown it.
Continuity mistake: During the fight scene inside the bathroom of Club Hell, the biker dude throws Marcus against the second-to-last mirror, breaking it. He then does it again... again against the second-to-last mirror. That is back whole, shattering it again. A huge chunk of it, practically the whole right half of it, comes off. But in the next shot, there's a small hole only, same when you see it in the background later. The closer look at the mirror that breaks much more probably is supposed to be the one that Marcus breaks off-camera with the cabinet. (01:07:10)
Other mistake: In the Ether truck chase, Marcus is driving and turning the wheel excessively, however the truck remains on a straight path. (01:07:35)
Continuity mistake: At Club Hell, Marcus is fighting with the flashily dressed bandit, Casper. Meanwhile, sharing screen time with Will Smith, a foot with red varnish on the toes. Cut to Martin Lawrence getting choked, and back to Will Smith. The foot now has no painted toenails. One could assume that since it's off-screen, more than a stripper was on stage. Mike is looking to his left both times though, and the girl that we don't see is lying down. Two performers would have to be crawling on top of each other. (01:07:40)
Revealing mistake: During the fight between Marcus and Casper, the fishtank breaks with the slightest tap of Martin Lawrence's foot, if any. (01:07:50)
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). (01:10:45)
Revealing mistake: As the Camaro explodes on the bridge, a piece of it notably flies off. You can see it fall down a cable attached to it. (01:12:20)
Continuity mistake: During the argument with the crazy and possibly murderous shopkeeper, there's a cut to Julie saying he's got "a cannon." He then shouts, "What do you want?" pointing said cannon towards where Martin Lawrence would be, but then in the reverse shot, it's pointed at Will Smith. Also, when they get him by surprise, their guns are in frame coming from the side, but they were standing in front of him in the rest of the scene. (01:16:00)
Continuity mistake: When Martin Lawrence is in bed with Tea Leoni and a dog and brings up the disturbing image of him "coming with thunder," she suddenly has her hands on her own chest in contrast with the previous shot. (01:17:40)
Continuity mistake: After the scene featuring pictures of Martin Lawrence with a big afro, Julia asks him how Marcus's wife is. She adds in a close-up that she must be pretty amazing. Look at her hand, palm against her cheek. That's not the pose she has in the next, wider shot. That's the pose she will get to a few seconds later when she says, "Watching him tonight," etc. (01:18:25)
Continuity mistake: Marcus falls on a big pile of trash after he unsuccessfully tried to infiltrate his own home. The garbage bins fall with their lids facing outwards, towards the street. Mike and Theresa lean from the window, and an overhead shot of the garbage mess is shown. By any basic rule of cinematography and film logic, that is their POV, what they see. However, they "see" the trash cans facing towards them, towards the house. (01:21:25)
Plot hole: Marg Helgenberger's investigation reveals that the mole has called Club Hell from the precinct. However, if you look at the scene, the villains are not expecting them (Casper spots them practically by accident and asks out loud what the cop is doing there; Noah looks incredulous), and they are even having their ether traffic in the open at the club front. Note that technically it does not say that a call was made before the blitz, but considering the mole knew about it first-hand, it's unfathomable they wouldn't tip them off. (01:23:15)
Continuity mistake: When Jojo is complaining about the guard dogs being lazy and overfed, the bracelet on his wrist turns between cuts. (01:24:20)
Audio problem: We hear Mike cock his two guns a variety of times in a row during the scene when he is threatening Jojo and Marcus. (01:25:25)
Continuity mistake: When Julie takes the key for the handcuffs from the cupboard at Mike Lowrey's apartment, she puts it down her right side. When she unlocks herself at the end in the car, she takes it from her left side. (01:26:40 - 01:39:35)
Continuity mistake: When Marcus's sons yell to call their mom, in the first shot she is holding sunflowers, keeping them straight, stem fully vertical. In the next shot, it's at an angle. (01:29:40)
Continuity mistake: Marcus opens a locker inside Mike's house and fetches two boxes of ammo from it. Look at his body when he is about to close it; he reveals the content of the locker, with a pair of handcuffs shining in the darkness of the bottom shelf. When Julie looks inside to get her handcuff keys, the handcuffs themselves are in a different part of the locker. (01:30:00)
Continuity mistake: When Theresa gets to Mike's apartment and confronts both real and fake Marcus, she mentions that lying to her is no use because she saw them on the news. Will Smith says, "That sh*t be having a slant," both hands free. In the next shot, he's holding a gun in his right hand. (01:32:10)
Continuity mistake: During the shoot-out in the lobby of Mike's apartment building, Chet calls 911 to report the event. In the first shot of him he is holding two dogs and in the next shot he is only holding one dog. (01:34:33)
Revealing mistake: In the mad taxi sequence, there is a shot of the taxi with sparks shooting out. If you look closely you can see the device that made the sparks. (01:37:00)
