Continuity mistake: When Casper gets on the plane, he starts shooting at Marcus from the airplane door. To the left of the door, there are two windows with tin foil taped over; the airplane is obviously in storage. The taping disappears when he fires again a couple of shots later. (01:46:30)
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: When the two female characters enter the fancy hotel room, they make a point to say they will only be there for a couple of minutes. It is daylight when they go in. The visit is cut short (the one that's supposed to be a few minutes long) because of a gun battle in which one of the women dies and the other escapes. The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)
Continuity mistake: When Marcus meets Julie Mott she attacks him with a bat. He takes the bat off her and moves to leave. The next shot of Julie Mott sitting on the floor shows the bat in the foreground. Cut back to Marcus still holding the bat and he asks her, "Look lady, you ain't got no more bats, do you?" (00:35:00)
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: Before Eddie Dominguez is shot sitting in the chair, the bad guy in the green suit is on the left of the large guy, but when the big guy pulls the trigger the man in green is on his right side. (00:27:45)
Continuity mistake: When Marcus and his wife walk up the stairs in the house, they are having a heated discussion and his wife (off camera) shouts down "and you don't even have your wedding ring on." At this point his wedding ring IS on his finger, then in the next shot the ring is NOT on his finger and Marcus attempts to put it back on. (00:44:10)
Continuity mistake: When Marcus is talking to his wife in bed about having some early morning sex, she gets up and he is leaning on his side. She tells him the kids will be coming any minute and when they do come bursting through the door, Marcus is now under the covers on his back. Given that we heard them approaching, there's no time for him to move. (00:10:25)
Continuity mistake: When Will and Martin are in Martin's car, just after they find the dead guy, watch the microphone hanging from the rear view mirror. Depending on the camera shot, it changes position. (00:20:00)
Continuity mistake: In the scene at the beginning of the film, when the villain of the piece shoots Julie's friend, he proceeds to turn the gun on Eddie and shoot him in the leg. After Eddie reels back in pain and falls into the chair, a conversation begins. Throughout the course of this conversation, the drool that flew from Eddie's mouth and landed on his right lapel, disappears and then reappears. (00:27:30)
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). (01:50:00)
Continuity mistake: In the party scene, when Fouche shoots Eddie Dominguez, his collar goes from being buttoned all the way to the neck and then being opened as the scene goes back and forth between shots. (00:27:25)
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: When Marcus wakes up towards the beginning of the film, he knocks a Florida snowglobe and some other stuff off the top of his alarm clock. In the next shot, the snowglobe is back on top of the clock. (00:09:30)
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)
