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'.

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)
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)
