Continuity mistake: When Kate runs out the church she goes through a side door but you can just make out the street from where they came in.
Continuity mistake: When Resputia is going down that slide it shows her a couple of times close up and she is on the part of the slide that is level for a long time even though that part of the slide is physicaly not that long. When they pan out she is just sliding off the tilted part and on to the level part and out of sync with the previous shot.
Continuity mistake: When Kate is Helping Norbit up after falling off the bike she goes from helping him with two hands, to holding the bike with one. (00:53:55)
Continuity mistake: When going down the big water slide, Kate's hair is wet. But when she stands up and is looking at Rasputia he hair is dry. (00:49:40)
Continuity mistake: When Kate and Rasputia are arguing at the water park. Kate's hands move between shots. (00:47:00)
Continuity mistake: Norbit gets soaked when he falls into the water riding his bike. When he gets to the church he is completely dry.
Revealing mistake: When the twins beat up Norbit (during the last shot of him getting beat up) you can tell that he was replaced with a very obvious dummy because his skin doesn't look realistic, and also it looks stiff as a board.
Factual error: When Mr Wong is threatening the 3 brothers, he pulls a harpoon from nowhere. (00:16:05)
Factual error: When Rasputia gets in the bath the amount of water that is displaced is not proportional to the amount of water in the bath. (01:11:55)
Audio problem: When Rasputia is hitting the crowbar in her hands the sound is out. (01:06:40)
Other mistake: Rasputia did not have enough time to get on the top of the white slide and there were several people before her.
Visible crew/equipment: When Norbit & Rasputia are about to have sex in the bedroom, before Rasputia jumps on Norbit you can see a crew member wearing a headset reflected on the bedroom wall.
Revealing mistake: When Norbit as a child pushes Rasputia on the swing (helps in slow motion) he is a digital effects blur, just before he is pushed away.
Continuity mistake: In the final scene in which Norbit's father hits Rasputia on her back, he is holding the whale spear with the arrow point at the back, then when it hits Rasputia it goes on her butt with the pointed side.
Visible crew/equipment: When they show the scene in which Rasputia appears exercising with the instructor with other members of the class, the reflection of a cameraman with jeans and white sneakers is faintly seen in the glass on the right side. (00:17:38)
Continuity mistake: Kate's skin color changes as she grows up. When Norbit was a kid she had a darker skin tone than when he saw her after so many years. (00:25:43)
Continuity mistake: When Rasputia is first at Buster's dance studio, in the mirror behind buster, it shows her facing forward with the rest of the class. Next shot is of her putting her things down. She is facing the back wall. When the scene changes back to Buster, she is again facing forward. (00:15:00)
Continuity mistake: When the chicken is being placed on Norbit's plate at the beginning it changes shapes through scenes.
