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)
Continuity mistake: Mike and Marcus go to meet Sanchez and Ruiz on the steps, Sanchez is sat down holding a doughnut (or something) in his right hand and a coffee in his left. A few seconds later, when talking about bongos, there's a close up shot and the items change hands. Back to a wide shot when Mike and Marcus enter they switch back. (01:41:30)
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: At the party scene in the early minutes of the movie, the bad guy who calls the two women to his place to "party" is shot once in the knee. Blood spurts and a gaping hole is made in his dark blue pant's leg by the bullet. Seconds earlier, the black hooker is shot three times. Where are the three gaping holes and blood on her solid white dress? Ah, there are none. (00:26:00)
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: When Mike and Max are talking in the equipment room, the clock behind them reads 3:27:40 twice - once before and once after Marcus drops the weights on his chest. (00:16:55)
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)
Continuity mistake: The taxi leaves the scene with a left turn. You can see it is missing the front hubcap on that side, but it was in its place just moments before; no further crashing happened. (01:37:25)
Suggested correction: The taxi's front left hubcap does not suddenly go "missing" between two shots. The reckless taxi hits the median island (sparks in this shot), hits three metal trash cans, and slams into a car. It's quite plausible to accept that, due to these jarring impacts, even though no further crashing happened the left hubcap has already been jostled loose; so during Martin Lawrence and Will Smith's iconic close-up shot, there is sufficient time for that hubcap to fall off while the taxi is off-screen.
I never said it was from consecutive shots, just that there were no other collisions. It didn't look loose in the slightest after all the collisions you mentioned. The last time we see it on screen, it is actually hidden by a fender that is not supposed to be there because of another mistake already reported, so we could say that is part of that other mistake, if anything.
Even though "there were no other collisions" that occurred, within the scene it's a reasonable possibility the hubcap could have been loosened by all the impacts from moments before. And the problem with stating "it didn't look loose in the slightest" after all the collisions is that a loosened hubcap can sometimes be completely unnoticeable visually while the vehicle is in motion. The hubcap could have fallen off as the taxi is driving away, while off-screen (blue fender shot notwithstanding).
