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: 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: After the blitz at the warehouse, Mike finds Marcus' messages on his phone. The time is 10:35. He has a brief heated exchange with the captain and "that guy" (there's always one) in the AMMO crew. Then he finally picks up one of Marcus' calls at 1:19. It wasn't a 3-hour argument. (00:45:25)
Continuity mistake: When Mike bends Manny over the butcher table, Manny's left hand goes from one side of the cutting board corner to the other. (00:33:20)
Deliberate mistake: To meet Manny, Mike walks through his store. The last obstacle is a PVC curtain. The camera has to go through the curtain, moving it and thus revealing its presence. However, it is definitely a deliberate artistic choice. (00:32:50)
Other mistake: In the montage showing Mike and Marcus' parallel (but also wildly divergent) lives, Marcus asks Alexa to turn down the volume. However, the video he is watching pauses instead. In the next shot, it is paused again, but on a different frame. And before the fan goes haywire and hits the screen, the screen is already turned off (but the breaker hadn't tripped yet). (00:32:00)
Continuity mistake: When Armando uploads the video of the shooting, Mike goes down in a different way than the original sequence, and the passers-by in the background are also different. (00:28:55)
Continuity mistake: Mike proposes a toast at the wedding to his "bad boys for life" motto. Reggie and Megan raise their glasses over their heads in the wide shot, but they have yet to in their close-up. Notice also Captain Howard next to them, as he is in every shot from that angle, but absent in the wider one. (00:23:30)
Continuity mistake: The first time we see the AMMO base, Captain Howard is visiting it to be debriefed about the progress in the investigation. Dorn mentions that they are investigating 4Chan. There's nobody standing next to him to his right, but then there's a close-up of his hands typing away at the computer, and there's a slender arm with short sleeves by his side. Rita is at the other side of the desk and Kelly in that scene is wearing long sleeves. (00:18:35)
Visible crew/equipment: In the opening shot of the foot race preparations, when Mike says that stretching is cheating, the camera casts a visible reflection on the sidewalk when it pans. (00:14:55)
Continuity mistake: When Marcus calls Mike a "dumba$$" about Rita, his bottle of product placement is tilted towards him, but in Mike's reaction shot ("What?"), it's perfectly straight. (00:13:45)
Continuity mistake: When Rita looks at baby Marcus's picture on old Marcus's phone, she holds it differently between shots. (00:13:00)
Continuity mistake: At the bar, Marcus and Mike begin their heart-to-heart talk about a family. Martin Lawrence's hands cross in different ways depending on the camera angle; when the camera is on Will Smith's side, Lawrence's left hand is lower on the table; when it's on Lawrence's side, he keeps it higher - watch his index when he's told about getting fat and breaking 'stuff'. (00:12:15)
Continuity mistake: When Captain Harris calls for a toast, "To Marcus," the guy behind him is pointing his phone in a totally different direction. He was pointing the phone towards him; now he starts the shot with the phone pointed away. (00:09:00)
Plot hole: Isabel's escape can happen just because it's off-screen. For it to happen, it's critical that every single guard (minus the one she kills) is inside the monitors' room, but not a single one stays behind, because it needs that no guard can see what is happening, in person or remotely. No amount of other blindly loyal fellow prisoners who are staying behind can cover not only her fully switching her clothes, but also transporting the body (who was dressed up in full, even if there was no need for that) from the middle of the room to the nearest washing machine. It also needs the paramedics to completely bail out of doing their job; she is not Hannibal Lecter, she is not wearing the face of her victim, she has just some blood smeared on her and superficial cuts.
Continuity mistake: When Marcus' daughter says about the baby's name, "it was Reggie's idea," suddenly the way Marcus holds said baby changes between shots. (00:04:15)
