When George and Matty Banks are practicing walking down the aisle in their hallway, Matty asks, "Is it right-together-left, or left-together-right?" to which George replies, "Right-together, left-together..." George's last minute reminder, and Matty's "cheat," written on his hand the day of the wedding, "Left-together, right-together," is opposite of what George says in the earlier scene. Oddly, none of the characters do any of the steps and just walk down the aisle normally.

In the opening credits, the wedding invitation says that the wedding date is in October. However, when Annie and her parents are discussing the wedding with Franck, they state that the wedding will take place on January 6th.

George's socks change color from the supermarket to the jail.

Annie's hair changes when introduced to the caterer.

The huge chandelier in the dining room disappears and reappears throughout the film.

The swans in the bath honk like geese when, in fact, they are silent.

When George pulls up outside his house to welcome Annie home, he states that Annie was in grammar school when they bought the house. However, the night before the wedding when they are outside playing basketball, she says that she's lived in the house since she was five.

Grammar school also can mean elementary school. Elementary school consists of children in kindergarten through sixth grade. A child typically enters kindergarten when they are five years old.

When the cops arrive to complain about the street being blocked with cars, the police car is seen in front of the house. If the street were completely blocked with the guests' cars, the police car couldn't have gotten there.

When Annie puts the ring on Bryan's finger at the wedding, it is obvious by the tan line and indention that he already has been wearing a wedding ring for a long time.

When Annie slides down the banister, talcum powder is visible on her behind.

The two young boys moving the cars from the street are too small to reach the pedals.

When George goes outside the night before the wedding to talk to Annie, the wind is whistling constantly (as it's about to snow). However, none of the trees or bushes are moving.

At the dinner table when Annie and George are arguing about her engagement, she responds to something he says by saying, "All right, hold on." However, looking closely, one can see she is saying, "All right, hold on a minute."

In every wedding with a photographer, particularly one with a high-priced wedding planner, there are a series of pictures of everybody in the wedding party, including the bride and her parents. There is even a scene showing the bride having some of the professional shots being taken at the reception. So it is almost inconceivable that the father and the bride would not have had a moment together after the wedding.

Howard calls George Banks at his shoe factory to tell him the wedding is going to cost $250 a head. It is not until much later in the movie, however, George tries to get the cheapest food for the dinner. Obviously the "per head" estimate could not have been made until the menu had been decided.

When Franck is showing the book of cakes to the Banks, the price of the cake is $1200. in reality, wedding cakes are sold by the slice. Therefore, the price of the cake wouldn't be a factor until the final guest count.

In the supermarket, George says that he's removing 4 hot dog buns from the packet of 12 because he only wants 8 buns to go with 8 wieners. Yet he does this with 3 packets of buns. So if he'd just taken 2 packs of 12, he would have the same amount as 3 packs of 8. But then he probably isn't thinking straight because he's stressed with the wedding plans.

Despite all the practicing and "crib notes" on 'left-together, right-together', it's clear that everyone is walking down the aisle in standard left-right, left-right instead of bringing the feet together after each step, then continuing with the opposite foot.

Annie's "old ten-speed" that George gets tuned up is a large men's road bike with racing components.

Annie's brother practices walking for the wedding and writes the instructions on his hand but then walks normally down the isle.

When George is headed home with Annie's bike, he says that he had it completely overhauled including "new seats", but it isn't a multi-person bike, so it obviously has only one seat.
