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)
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)
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)
