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: Inside Mike's apartment, Marcus is fighting with the answering machine. Julia puts the bag with one of her dogs down on the couch. You can see her set the bag next to the gap between two pillows, but in the next shot, it's next to the armrest. Also, the strap is off the couch the next time the bag is in frame once he mentions the "peak hours," but nobody touched it. (00:43:10)
Continuity mistake: When the captain greets the Bad Boys, saying "Welcome to our nightmare," Joe Pantoliano is wearing no glasses, either on his face or around his neck. Cut to him opening the door to the vault; he's now wearing a retainer with glasses. The shots are not technically consecutive, but he was only leading them through a corridor. There's no reason why he'd feel the urge to wear his glasses all of a sudden when he didn't even have them on hand. (00:12:25)
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: Inside the suite, Julie takes a sip from Max's glass. Behind her, Eddie Dominguez giggles, "Watch your step." He rubs his already powdered nose, then touches the glass. Cuts to a wider angle, and Eddie is repeating the exact same movements - but Julie isn't. (00:25:00)
Continuity mistake: The Bad Boys enter the precinct, made into a crime scene, through an overhead shot. To their left as they come in, a cop in a suit with fair, curly hair makes a turn around a desk corner. It cuts to Will Smith saying, "Hey bay-beh!" tapping Francine's desk. A different cop is behind them, then it cuts to a wider shot with Martin Lawrence in a more subdued greeting, and the same cop from the first shot does the same turn as before. (00:12:10)
Continuity mistake: After the truck smashes through the drug deal location, there's a brief intermission with Julie trying to open her cuffs, saying "Go, go, go," and then Sanchez fires at a bad guy on the scaffolds, killing him. A few seconds of hectic action pass, Julie detonates the barrels, and Marcus looks up and shoots another villain on the scaffolds. As he falls, you can see another one close by; it's the same guy who died earlier. (01:44:50 - 01:45:25)
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 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: Fouchet dies with a dramatic close-up of Tcheky Karyo tilting his head to the left as he draws his last breath. Then an overhead shot just shows him facing up. (01:53:10)
Continuity mistake: After Fouchet is hit, he still manages to crawl a bit on the tarmac, his head well away from the painted part in the overhead shot. When Marcus taunts his "punk a$$," the close-up on Tcheky Karyo shows him against the white painted asphalt. (01:51:54)
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)
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)
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: 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)
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)
Continuity mistake: Marcus is showing mugshots to Julie on the computer. He gets on the mugshot of a "Trafficante, Noah," which turns out to be the right guy. He already hit "next," though, and the picture of a "Catrini, Robert" starts appearing. Julie tells him, "Go back, go back." Marcus is already on the profile of a "Leachman, Todd," but a single click brings him back to Trafficante. Catrini disappeared. Funnily enough, in a later flashback (when Julie, at home, holds a gun apparently for the first time and decides to go to Club Hell and see if she can single-handedly take on the Mob) the pictures are in the right order; Catrini came back. (00:55:55)
Continuity mistake: Running suspect pictures, Tea Leoni tells Marcus that he's eating "flesh." Martin Lawrence's fingers change position on the sandwich between shots almost constantly throughout the scene. (00:54:25)
Continuity mistake: Inside Mike's apartment, Julie asks Fake Mike who is the guy in all those pictures. In close-up, you can see some frames have been readjusted to look better; look at the ornate silver frame next to the picture of Mike with a basketball. The two frames were a couple of inches apart; now they are closer. (00:53:25)
Continuity mistake: On the basketball court, Mike shows off nailing a three-pointer on his first try when the captain couldn't land any. When he looks at Will Smith's ball flying over him and into the basket, the captain has a cigar in his mouth, but Joe Pantoliano in the reaction shot that follows has none. (00:50:45)
