Continuity mistake: Mike infiltrated the spa to try and stealthily deploy Marcus Jr, but he is spotted. Theresa was getting pampered with both hands crossed on her belly, the bow of her belt tied an inch away from her hands. In the reaction shot, her relaxed position begins with her hands on top of the bow. Moreover, she turns and raises her head in those close-ups, while from the other side she is still supine, back on the bed, masseuse's hands on her shoulders. (00:49:20)
Other mistake: When Marcus receives the phone call from Theresa after the bad car 'accident', the phone screen is blank in the wide angle, and in close-up displays a 10:35 time, which is incompatible with what was already shown before. Moreover, Marcus's right hand changes position on it/off it between shots. (00:51:20)
Continuity mistake: When Renny makes a splash on Theresa's car, the post casts a shadow on the radiator, next to an inch away from the Nissan logo. Mike and Marcus take their time to bicker for a few seconds, and when Marcus checks the car with its now embedded corpse, the shadow is already on a portion of the logo. (00:51:20)
Continuity mistake: The biker assailant and Mike crash onto a table outside the Broadmore Hotel. The area they land on is in a large shade. The biker recovers a moment later and gets up in sunlight. (00:52:30)
Continuity mistake: Watch Mike when he joins Captain Harris at the bleachers. The kid to his right (left of the frame) holds a phone in the closer view; he had none in the long shot. (00:54:20)
Continuity mistake: In the scene of the sniping on Mike and Harris, in close-ups, Armando's face is fully lit, but when Zway-Lo is in frame, the shadow from the side is wider and there's a thin shadow (from the post) intersecting his right eyebrow. (00:57:25)
Continuity mistake: When Mike kicks Picante Jenkins's door open, the door closes shut behind Marcus and him, but is slightly open in inconsistent ways during the rest of the scene. (01:02:00)
Continuity mistake: In the scene at Picante's 'office', the camera cuts away for a split second when the unlikely accountant taunts Mike, calling him "butterscotch." His gold chain was under his tank top; now it's above. (01:03:45)
Character mistake: After the scene at the obese accountant's place, Rita is going through the case with Mike. She says, "Judge, prosecutor, criminal informant, the captain and you." She didn't mention the forensics expert, who is also on the board. (01:04:35)
Character mistake: When the good guys plan their next moves at AMMO, they show on screen the profile of Taglin, the boss killed early in the movie by Armando. His profile says that he was born on 1/17/68. Then in the third paragraph, it says, "First arrest age 16, 4/20/82," and that he fully served 18 months in prison. The fourth says his second arrest was on 8/19/83. So, 14 years after his birth, he was 16, and he was arrested 14 months into his 18-month jail term. Got it. (01:06:05)
Visible crew/equipment: During the chase, Zway-Lo attacks the Bad Boys with a car that is being towed, causing it to explode and fly off the bed of the truck like a projectile. Complete implausibility aside, every time you see a glimpse of the men in the truck cabin, there is a 0 reaction from them. The truck goes on as normal, nobody flinches in the frontal view, the guy in the passenger seat barely glances to the left when Will Smith drives his bike past the window, stone-faced. (01:18:50)
Factual error: When Armando fired the M141 SMAW-D from the helo, there was no back blast out of the other side, not to mention the other man is the back would have maybe had his face blown off from the back blast also. (01:20:10)
Continuity mistake: Marcus, in his half of the sidecar, is on a collision course with a truck (after they show the truck driver steering to avoid Zway-Lo). In the more dynamic, wider angle, he is screaming, body stiff and hands off the machine gun. A close-up of Martin Lawrence shows him still clinging to the weapon. (01:20:30)
Continuity mistake: When Mike tumbles on the flatbed truck after bouncing Marcus's sidecar out of the way, he rolls head to the left, feet to the right. It's the other way around at the cut. (01:20:40)
Other mistake: When Mike goes through Isabel's file, it says that she escaped prison on April 10, 2019. However, the scene is set on August 22 of the same year, 2019 (it says the date right there as it checks "the last 2 months" of phone calls with Dorn). Mike was shot at least 6 months before (it says "six months later" in the wedding scene, which is where he makes his reappearance after the shooting scene, possibly more time passed). Mike was shot only after Isabel got out of prison, so that's impossible. (01:24:30)
Continuity mistake: Somehow, Marcus got a plane seat right behind Mike. He puts his hand by Mike's headrest, and in the same shot, he removes the hand from that position. But the hand is still there in the next one. (01:30:50)
Continuity mistake: When Marcus asks to switch seats with a passenger who is all too eager to go for it, his left hand changes position between shots. (01:32:00)
Continuity mistake: In the Mexico hideout, when Dorn gets through the door with a cheerful "¡Olé!", the jacket on his shoulder changes length between shots. (01:35:15)
Other mistake: Mike has a spycam in the locket, but Isabel tears it off his neck. However, the device immediately stops working. Unless the 5' woman crushed the actual metal instantly in her fist, it should keep working and broadcast at least the audio, even if she snapped the cord free. (01:39:25)
Continuity mistake: When Dorn does a Superman punch on a bad guy during his sortie on the left flank with Rafe, the guy he attacks had a machine gun in the previous shot, but he takes the punch already hands-free. (01:44:10)
