Father of the BrideGoofs
Continuity
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.
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.
Annie's hair changes when introduced to the caterer.
Factual errors
The swans in the bath honk like geese when, in fact, they are silent.
Revealing mistakes
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 very 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.
Miscellaneous
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.
Audio/visual unsynchronised
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."
Plot holes
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 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 was 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.
Character error
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.
