Continuity mistake: When Skeeter is making the "rice cake, banana and wheat-germ sandwich" during the scene the broken sandwich on the plate and also the banana on the counter keep on changing their position. Also, in the closeup of the sandwich after Skeeter has poured toothpaste on it the jar of wheat-germ is not visible, but in all the other shots it is right beside the plate.
Continuity mistake: When Mickey and Skeeter are in the hotel kitchen talking about Kendall's promotion, Mickey is eating food off a plate. During the scene he keeps changing from eating to not, and food appears and vanishes from his hand and his hand changes from being by his face to down, etc.
Continuity mistake: In the beginning of the movie when Marty is tucking young Skeeter into bed, as Marty is sitting beside Skeeter's bed we can see the slatted blinds behind him are almost down to the bottom of the window. But as the scene comes to an end and the camera pulls back from out of the same window, the blinds are now almost pulled to the top.
Continuity mistake: When Skeeter arrives at his sister Wendy's house, he walks into the kitchen and meets Patrick and Bobbi. He says he has some presents for Bobbi, and Patrick turns around and leans his arm on the back of the chair. In the next few shots his arms keeps moving from resting on the back of the chair to down in his lap.
Factual error: When Kendall is about to implode the school, the demolition practices are completely unfeasible. The school would be completely gutted, with all glass, copper, and plumbing removed (the building simply looks cleaned out a bit); additionally, significant structural damage would be intentionally introduced to weaken the internal support (every wall is largely cored); further, the school building and/or surrounding buildings would be sealed in tarps to minimize damage spread; finally, the crowd of protesters and onlookers would be at least a quarter-mile away. Even given this is a bit of a fairy-tale story, the demolition techniques are completely incorrect on several levels.
