Revealing mistake: During the first chase, when the Batmobile joke is said, skidmarks from previous takes are visible on the road. (00:02:55)
Continuity mistake: When Marcus opens the Porsche's door, his left arm is on top of the car or lowered depending on the shot. (00:03:20)
Continuity mistake: When Marcus sees his baby grandson, a nurse in the background is picking up a white diaper. In the close-up the diaper is now blue. (00:03:35)
Continuity mistake: When Marcus is holding his baby grandson, the position of the woman next to him is inconsistent in every single shot. (00:03:55)
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)
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)
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 Rita looks at baby Marcus's picture on old Marcus's phone, she holds it differently between shots. (00:13:00)
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)
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: 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)
Other mistake: After Mike is gunned down, Captain Harris visits the AMMO team hard at work to figure out who could have done it. However, it seems unlikely that they are so dedicated to their job that none of them had time to change clothes when we see another briefing after Armando's three other killings, which happened across at best days, more likely weeks, or the six months of Mike's recovery. Everyone is wearing the exact same thing. (00:19:00 - 00:21:00)
Character mistake: Following the killing of a DEA forensics agent [guy sniped on the boat], a newspaper clipping is shown on screen. Underneath the headline of the article, "Assassinations" is misspelled from omitting an S in the second set of S's. However, if you read the article, you will see the word is correctly spelled in the first paragraph. (00:20:28)
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: 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)
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)
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)
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)
Continuity mistake: When the Captain, Detective Lowry and Rita walk to the elevator, she is wearing black boots. When they exit into the ops room, she's wearing high-heeled shoes. (00:35:40 - 00:36:40)
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)
