Continuity: When Madea is in the car coming back from court, Nikki smarts off at her and Madea turns around to hit on her. While this is going on, you hear brakes squealing and the driver is moving the wheel like the car is out of control. Yet, the background never changes, stays level throughout this scene.

Madea's Family Reunion mistakes
Deliberate "mistake": In the scene at Frankie's house, Vanessa panics when she awakens and realizes Frankie and the children are away. When they re-enter, Frankie is heard telling the children that the carton he is carrying is "ice cream for Mommy." Frankie asks to speak with Vanessa in another room and sets the carton on a table. The sound of the connection makes it obvious the carton is completely empty.
Other: Frankie tells Vanessa that he brings his son to the park on Saturdays and would like to meet her there. It shows in another scene from that day that Nikki, the foster child, had been in school that day so it couldn't have been a weekend day.
