Continuity mistake: James and Maya open the cargo container and find pile of of drugs and weapons stashed there. Ice Cube holds the automatic weapon in different ways depending on the angle (just look at the strap), and when Pope gives them a shout you can see also Olivia Munn reach for the gun (which is on the cargo bed) using her hands in a radically different way. (01:24:40)
Continuity mistake: AJ distracts the baddie that was shooting Ben with his assault rifle, and Ben manages to gun him down. The man dies falling in two different parts of the street - just look at the cracked section of the asphalt. (01:26:50)
Continuity mistake: When James quite anticlimactically shoots down Pope's lead henchman to save Maya, he is completely in the open in the last shot of the sequence, but he was leaning for cover against the container all the time before, and was never shown moving, quite the opposite. (01:27:15)
Continuity mistake: James holds Ben by the vest for the big climax - but also by his jumper, when the shooting is over. (01:30:35)
Continuity mistake: The brothers in law are shaking hands with Captain Hernandez in front of the district. There's a woman with long brown hair and carrying a purse. She keeps passing them by walking up the stairs, twice with a friend with a purple top, once on her own, and comes down the stairs not too long after. She's not the only extra recycled / passing a few times in succession, for instance a bald black man in a dress shirt. (01:31:20)
Continuity mistake: When a drunk AJ tells Ben "Happy Kwanzaa, sorry for your loss", a woman in a black and white dress, with a tattoo on her arm, passes by them twice. (01:33:50)
Continuity mistake: When at the wedding Ben calls Maya "handsome" and James drinks from his glass, said glass is in his left hand at first, then changes to right mid-gesture. (01:34:15)
