Continuity mistake: When Baby Joker and Joker are counting the money in the room and they get interupted by Little Joker and the two girls they shove the money in the pump. Then when Craig gets into the room and opens the drawer with the pump and pulls out some money it is all wrapped up in rubber bands.
Continuity mistake: In the scene were Day-Day and Roach are being interrogated by the Joker brothers, all of the brothers are shirtless, but later when Joker kicks the three girls out of his house he appears in the doorway with a shirt on. In the next shot when he continues interrogating Day-Day and Roach he is shirtless again.
Continuity mistake: When Craig first meets Karla her brother Joker send Cheeco after him and you see Cheeco running out of the house, through the garage to chase Craig. The camera angle changes and you see Craig going back to his cousin's house and he turns to see Cheeco coming out of the garage again.
Continuity mistake: When Day-Day's dad goes into Joker's house to rescue him and Roach, his dad walks up to them as they are laying on the floor and you can see some potato chips and other things on the floor next to them. The camera angle changes to a close up and you now see some things on the floor next to Roach's head that were not there in the previous shot.
Continuity mistake: When Uncle Elroy shows Craig his swimming pool he fishes a used condom out of the hot-tub. In one scene he is holding it upside down so the water can run out of it, but in the next scene he is holding it right-side up, the water is still inside and then he empties it.
Factual error: At the end when the cops come after the fights. Ice Cube seems to be able to 1. tell the cops who to arrest even though the cops just arrived. And 2. Walk right out the front door of a house being raided by several cops with a the cash cylinder and no-one even seems to care. In reality everyone would have been arrested in handcuffs, questioned at the scene, and only released when or if it was determined they were not doing anything illegal.
