Continuity mistake: After Norbit crashes on his bike and causes the old men to laugh, he gets up and has multiple leaves in his afro. After two simultaneous takes, they disappear, with no explanation - or wind. (00:54:15)
Continuity mistake: Just before Rasputia chases Norbit out of the house, we see that his shirt is unbuttoned and untucked, yet in the next shot (where he is running past the mailman) his shirt is buttoned and tucked in. Two shots afterward, when he gets hit by the car, his shirt is unbuttoned and untucked like it was before.
Continuity mistake: When running into the church, Rasputia's left foot goes onto the top step. The camera cuts and her right foot is first onto the top level. (01:06:25)
Continuity mistake: When Norbit is yelling outside to Kate from the basement, you see him glance over at the potato on the fork that has acid poured on it. However you can see there's more left of the potato's face than what was melted off a few scenes earlier.
Continuity mistake: Sticks disappear and reappear from Norbit's hair when being hit at the end of the film. (01:27:10)
Continuity mistake: After Kate has come down the slide she gets out and is completely dry (look for footprints) (00:49:45)
Continuity mistake: When getting stuck in the turn-style at the water part, Rasputia changes direct between camera cuts.
Continuity mistake: When hit on the head Norbit's arm goes from beside him to on his chest in an instant cut. (00:39:30)
Continuity mistake: The "evidence" Norbit has, changes colour and wetness in different consecutive shots. (01:27:15)
Revealing mistake: When Rasputin goes through the wooden barrier at the water park it is a clear CGI. (00:50:20)
Other mistake: The subtitles say "Lloyd" when Norbit is talking to the dog but the credits say "Floyd". (01:09:20 - 01:34:00)
Revealing mistake: When Norbit falls off the bike and makes the men laugh a second time it is the same footage as the first time he did it. (00:52:30 - 00:53:40)
Factual error: After Kate's wedding is broken up and everyone leaves the church and ends up fighting in the town square (using shovels, pizza oven paddles, etc.) you can see a post office in the background. The city and state say "Boiling Springs, Tennessee" followed by the zip code 87168. This isn't a real zip code according to the US Post Office, and zip codes beginning with "8" are closer to the west coast (i.e. in Nevada or Utah). Real Tennessee zip codes begin with 37's or 36's. (01:29:35)
Continuity mistake: When we see Kate getting ready to go down the slide there is a huge line of people waiting for the slide. Also Rasputia is at the bottom talking to Norbit. Yet after Kate gets off the slide Rasputia is next. (00:49:10)
Continuity mistake: When Norbit collapses trying to carry Rasputia over the thresh-hold, he is lying away from the door frame but next shot he lying against it. (00:13:30)
Continuity mistake: When Norbit falls off the bike both wheels are on the floor. But next shot one is in the air and spinning. (00:53:40)
Revealing mistake: When Rasputia throws the old lady, when she is flying through the air it is a double. (01:30:05)
Continuity mistake: When the dance teacher leaves, he is naked. When he is seen 2 seconds later he has managed to get boxers on. (00:21:50)
Continuity mistake: When Rasputia is having pizza, a shot shows one piece being taken but she then has two in her hand. (01:01:50)
Revealing mistake: When Norbit runs on top of the church pews you can see foot placements on the pews. (01:28:50)
