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: 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)
Audio problem: When Noah and Casper follow Julia on the roof and then narrate to the audience her amazing off-screen escape out of their range of sight and fire, Casper says two lines ("I can't believe she made it!" and "Jesus!") without even moving his lips. (00:28:55)
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)
Visible crew/equipment: When Will Smith breaks through a window when the bad guy lurking at the madam's place throws him into it, in the second shot of the stunt (the one with the camera at ground level), the camera wobbles, hit by the debris right before it cuts to the side view. (00:33:05)
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: 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)
Other mistake: Marcus and Julie identify the correct suspect; it's one Noah Trafficante (his last name literally means 'smuggler', so you know he's up to no good). The profile says, "WANTED. Reward; £18,000 Reward Armed and Dangerous." Barely a minute later in the movie, in a scene at the police station, Mike asks for his parole jacket and Francine tells them he works at Club Hell. (00:56:10 - 00:57:40)
Other mistake: In the scene at the police department when Mike ends up pranking Marcus by pretending to flirt with his wife on the phone, the janitor keeps mopping the same small corner of the office for two minutes straight of screen time, and the same cops can be seen doing the same movements at least twice (for instance, one wearing a denim shirt and white tank top and one with a pink shirt). (00:56:40)
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)
