Continuity mistake: When Mrs. Fuller is telling Big Momma that the girls walking by in the spa are Victoria's Secret models, the gold watch on Big Momma's left hand is missing and you can see the seam of the costume on Big Momma's wrist. And in the next shot, the watch is back again.
Continuity mistake: During the bingo scene when Big Momma is about to fight the drunk elderly women, the picked numbers on the bingo board change from shot to shot dramatically.
Factual error: You can tell that the "Brillo pad" Andrew eats is not real as Andrew would have been VERY ill due to the cleansing chemicals on the pad and the fact that the metal would have cut his mouth considerably. There was no blood, no foam coming out of his mouth (the box says Oxy action implying foam), and he keeps eating despite that the taste would have been horrible.
Factual error: I used to cheer at major competitions like at the end of the movie. These competitons have VERY strict rules concerning music and acceptable moves. Carrie's cheer team would not have been allowed to compete with the song they use and some of the moves they do. They would have been considered vulgar/ inappropriate for their age group and the team would have been immediately disqualified.
Continuity mistake: When Leah Fuller is sitting down to watch the cheer club class at her house, her ponytail is on her right shoulder. But in the next shot, the ponytail is not on her shoulder.
