Continuity mistake: Inside the Al Capone suit, Captain Howard asks the Bad Boys who the guy on the chair is. "Eddie Dominguez," says one. The captain is chewing gum, arms down at his side. In what's supposed to be an immediate follow-up, Martin Lawrence adds, "Yeah, the ex-cop." Joe Pantoliano in the foreground is taking a puff from a cigar instead. (00:29:05)
Continuity mistake: There's a rubber flower (a toy sunflower with sunglasses) on Mike's desk. When Captain Howard answers the phone, it goes from fully straight and vertical to hunched over as the shot changes. Throughout the whole duration of the scene, the flower is straight in the wider shots with Pantoliano standing by the desk, and 'wilted' when the framing is focused on Martin Lawrence. (00:33:20)
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: Marcus ends the phone call with Julie, saying, "Mike to the rescue." He suddenly has his left hand on the microphone. (00:35:00)
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 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 they're in the basketball court, Will Smith marches over to Martin Lawrence, saying "you left a strange hooker in my apartment?" He's holding the ice pack in his hand in the wide shot, but in close-up it's not visible. (00:48:55)
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)
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: 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: 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: 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: 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: 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)
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)
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: 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)
