Visible crew/equipment: When Ben and Andie are on Staten Island and pull up in the driveway on the motorcycle, if you look at the black car next to them you will see a cameraman's reflection.
Continuity mistake: In the scene where Ben is on stage and getting the two guys to stop Andie for her to also come sing with him, Ben has the microphone he is using plus another in his hand. The second microphone goes away and comes back several times before he finally picks one up on the piano to give to her.
Factual error: In the scenes where Andie and Ben are at the NBA Finals games, it always shows a shot of the basketball players. When the clock is winding down, and it is supposedly a very close game, it shows the bench players of the Sacramento Kings on the court. Players such as Lawrence Funderburke, Gerald Wallace, and Scot Pollard only play when there is a huge difference in the scores of the teams, but in the movie, they are supposedly playing a very close ball game. Also, this movie takes place in 2003, which is the year that the Kings got new uniforms, so they wouldn't be playing in the ones that they were wearing. Also, when a team in the NBA enters a finals game, they wear new jerseys that have the NBA Championship Trophy stitched onto them. In the movie, neither team had this on their jerseys.
Continuity mistake: When Michelle puts the wallet down the first time, she puts it on the book. When she puts it down the second time, she puts it directly on the table. In the next shot that shows the wallet it is back on the book.
Continuity mistake: When Kate Hudson is eating the hamburger, she takes one big bite. And in the few shots after that it can be seen that one perfect bite has been taken out of the burger. In the last shot you see of the burger from behind Kate Hudson nearly 1/4 of the burger has been eaten.
Continuity mistake: When Ben's mother goes to hug Andie, she puts her right hand on the back on Andie's head and when the camera angle changes to a side view the mother's hand is now on her shoulder.
Continuity mistake: In the scene where Ben is teaching Andie to ride his motorcycle several people people can be seen on the boardwalk with them, which disappear in the aerial angle.
Continuity mistake: When Ben is talking to Tony and Thayer about him getting the account, he punches fists with each guy and when the camera angle changes to behind him, you see him punching fists with the second guy again.
Continuity mistake: When Ben asks Andie to go to the party, he tells her that he wants her to go as his girlfriend and she puts her right hand on his shoulder. The camera angle changes to a shot from behind and her hand is now on his chest.
Character mistake: In the very first scene in the film, the magazine covers are flashing up. There is an article called 'How to get a better bod in 5 days.' If you read the beginning of the article it says 'It Can Done.'
Continuity mistake: When Andie first meets Ben she has her drink in her right hand but as the camera angle changes to a wider shot the drink is in her left hand so she can shake his hand with her right.
Revealing mistake: The first night Ben brings Andie home, he starts the music on the CD player, but no CDs are spinning at all. Yet, the music still plays. He also changes the track mid-scene, and still no CD is spinning.
Continuity mistake: When Ben and Andie are sitting on the couch, Andie has a wedding ring set on. When they go into the bedroom she doesn't.
Continuity mistake: In the final scene on the bridge, after Andie gets out of the taxi cab her hair is wavy and frizzy. Then in the next shot when she is standing next to the taxi cab just before the kiss her hair is different, it's curlier.
Continuity mistake: In the scene where Andie and Ben are looking at the photo album and Ben's mom calls for Andie, the phone keeps switching hands. First it's in her right hand, then her left, and back to her right by the end of the phone call.
Other mistake: In the scene where Spears is walking down the street and stops at the magazine stand to buy Composure Magazine, she hands the man a bill. The seller gives Spears her change without even looking at the money he was handed. How does he know what the exact change should be?
Other mistake: In the movie, the dog that Andie bought for her and Ben had a black face. But in the inside of the dvd case by the chapter selections the dog in that picture is all white.
Continuity mistake: When Ben goes to get Andie's coke at the Knick game, he grabs the coke from the vendor with his hand on the side of the cup. The next shot shows him grabbing the coke from the top as he turns and runs away.
Continuity mistake: When the ladies exit the meeting and are walking down the stairs after deciding that Andie will be writing the column on how to lose a guy, right before they meet the two executive ladies, Andie is seen starting to open up her bag to put her daytimer in. The camera angle changes to a wide shot and the daytimer is gone and the bag is closed.
Factual error: The Knicks are supposedly playing at home for games 1, 3, and 7 of the NBA Finals during the course of the film. This is not possible for two reasons. First, games 1 and 3 are never played in the same location(either 2-3-2 or 2-2-1-1-1). Second, if the NBA Finals were to extend to 7 games, this would typically take place over two weeks and not the 10 day premise of the film.
