Before the drive-by shooting at the end of the film, Illena's cousin is seen loading an Uzi machine pistol, and when the shooting is about to begin, he aims this gun out of the car window. However, when the shooting actually starts, he has changed over to a TEC-9, a completely different type of machine pistol.
When the cousin of the girl Caine impregnated gets into the car for the drive by, he is seen getting into an older model car which is clearly a convertible. When they arrive and start shooting they are riding in a hard top Pontiac.
Before he beats up Chauncy at Ronnie's party, Caine asks O-Dog for his gun. O-Dog hands Caine his Glock. However, when the beating starts and Caine is pistol-whipping Chauncy, the gun has become a Beretta 92F.
When Kane goes to the BBQ he pulls up to see a red civic, he sees the girl and stops behind her, when he's talking to her outside of the car the civic is black, then when he says that he will call her later and walks off the car is red again.
When Cain first meets Illena, he parks his car behind hers, blocking her in. The scene switches to the barbecue where A-Wax and Stacy see Cain talking to Illena. When the scene switches back to Cain and Illena, Cain's car is no longer behind hers.
Ilena's weight fluctuates throughout the film. When we first see her at the barbecue, she is somewhat slim. When she is shown talking to Caine on the phone, which because of her pregnancy is presumably within a month later, she is noticeably heavier.
During Ronnie's party scene, Caine's voice over says that the party was at the end of the summer. During the party Chauncy tells a girl that "me, A-Wax and Caine went to a Lakers game last night." The NBA season starts in November and has no regular games being played at the end of the summer.
