Corrected entry: In several shots you can see that the supposedly-identical girl twins are not really twins, for example their hair color is different. You can also tell that some of the kids are really relatives, such as FedEx and one of the girl twins.
Corrected entry: On the Baker kid's first day of school we see everyone go to school except for Henry and Sara.
Corrected entry: In the scene in which the kids prepare to soak the underwear in meat, the underwear comes out of the dryer as briefs. When the kids are drying it, it has become a boxer brief, presumably because it's larger and makes for a better shot in the closeup.
Corrected entry: When Tom is about to take the family picture, Mark walks out in black. However, why was Tom about to take the picture without all of the kids?
Corrected entry: When Sarah gets up from her homework desk to watch Dylan's birthday party, she is in her bedroom and the desk is behind her when she gets up. When she turns around after she looks out the window, the desk is gone and she is in the hallway.
Corrected entry: When Tina and Bill arrive to greet the Bakers, the Bakers dog leaps up at the neighbours, and Tom has to hold back the dog. He is bending down holding the dog, then Tina says "I don't eat meat." In the very next shot, Tom is now standing normally, and their dog has vanished.
Corrected entry: Right after the scene where Sarah Baker decides that they're going to Dylan's birthday party, you see the kids climbing down a rope at the side of the house to exit. You then see Kyle Baker (wearing blue) climbing down the top of the rope. Then when the shot changes, Kyle is throwing down presents to Sarah.
Corrected entry: When Steve Martin ends up covered in breakfast just after trying to catch Beans there is a piece of toast on his right shoulder. When you first see it it is on the front of his shirt, but then the shot changes and when it comes back to him the toast is at the back of his shoulder.
Corrected entry: In the scene where Hank reminds Nora of a previous encounter with her family, he says, "Maybe next time it was my pants, but maybe next time it will be my face". He obviously meant to say, "Maybe last time it was my pants..."
Corrected entry: When Charlie and Hillary Duff first go to school in their new town, Charlie hits the end of the car with his leg and the alarm goes off. The alarm should already be going off because the group that made fun of Charlie and Hillary was already sitting on it.
Corrected entry: When Bonnie is interviewed on radio and taking calls from listeners, no headphones are used. The sound from the speaker in the studio would go back into the microphones and create feedback, no radio show would be done like that.
Corrected entry: How is it possible for only the dad to work, coaching a local football team, and earn enough money to support 12 kids? This would be impossible in real life, but in the movie, they live comfortably, and appear to have no financial strain other then the daughter asking for no more hand-me-downs.
Corrected entry: In the scene where Sarah goes to get the dishes out of the dishwasher, she says "Mike's athletic cup?" Mike is her younger brother, who probably doesn't play, and would not use a cup.
Corrected entry: When the twin boys are the only children left at the football game, they are hitting each other with the W and the E from 'We love the coach'. At the end of the movie when the whole family returns to the field, the 'WE' is on one piece of cardboard.
Corrected entry: A college football stadium that seats 80,000 people would not have a football team consisting of 10-15 guys.
Corrected entry: When the new neighbours are walking home from their 'welcome' visit, they're walking along a footpath (US: sidewalk), yet they live directly across the road - no need to walk anywhere except straight across (as is done by the Baker kids on their way to the neighbour's birthday party later).
Corrected entry: At Mark/FedEx's first day at his new school, he runs into some bullies who knock his glasses to the floor. He kneels down and has to feel around on the floor in order to find his glasses, so obviously his eyesight is so awful that he can't see even 10 inches in front of his face. Yet in a later scene, he's laying in the bed and rolls over to look at a picture of his Mom and him on the bedside table, and sees it WITHOUT his glasses.
Corrected entry: When Steve Martin announces that the family is moving, the kids cast votes on pieces of paper. When he counts them he says "Eight no's, 3 yes's and 3 maybe's". That is 14 votes, but the oldest daughter is living in Chicago and wasn't at home to vote. There should have only been 13 votes.
