Other mistake: When Andie goes over to the diamond display (at the party) she isn't wearing any jewelry, and touches her ears a couple of times, demonstrating there's nothing on them. Later on she is seen wearing 'Isadorra' (the yellow diamond necklace) and a pair of matching earrings, which are certainly large and sparkly enough that they would have been visible if she was wearing them earlier. When security chases after Andie after she leaves, they only take back the necklace. I guess that the diamond earrings weren't that important. (01:39:30)
Continuity mistake: When Andie and Michelle are crashing at Michelle's place near the end of the movie, the cat on Andie's lap faces left, toward her head. When Michelle jumps up to answer the door in the very next shot, the cat is facing right before he jumps down. (01:42:33)
Continuity mistake: When Tony is trying to get Ben to read Andie's article about him in Composure, the title of the article changes from shot to shot. In the first shot, when Tony is reading some quotes to Ben, the title is in blue across the top of an all white page. In the next shot, when Ben is holding the magazine with Andie's article, the title is in red and black with a big pink heart in the background. The magazine also shows the same paragraphs on different pages when Ben turns a page. (01:45:20)
Continuity mistake: When the guys are looking at Andie's purse on Ben's desk, the two handles are sticking straight up but the close up shot shows the front handle folded over, and then the next wide shot shows them both up again.
Continuity mistake: In the scene where Andie and Ben are riding the motorcycle and she is wearing a white tank top, you can see the outline of her bra. When they go back to his parents' house and Ben takes off Andie's tank top in the bathroom, she doesn't have a bra on.
Factual error: In the very first scene in the film when the magazine covers are flashing up, the very first one has a headline which says "loose that belly". For a film whose title has the word "lose" in it, you'd think that they could spell this properly.
Continuity mistake: In the scene where Andie is trying to get Ben to look at the photo album and Andie starts to cry, Ben covers his mouth with his fist. In Andie's close up, you can see that Ben has his hand beside his beer bottle. When it shows a close up of Ben again, his fist is still on his mouth.
Continuity mistake: During the Knicks game, there is a shot of the scoreboard with about one minute left. The main score says that the Knicks have 93 points. However, if one adds up the player-point totals on the left (42, 9, 21, 14, 8), the Knicks supposedly have 94 points.
Continuity mistake: When Ben and Andie are visiting Ben's parents, Ben takes the baby to change his diaper. When he comes back, the baby has a blanket wrapped around him, but when Ben passes the baby to his father, the blanket is not there any more.
Continuity mistake: Towards the end of the movie when Michelle and Andie are watching the Final Game at Michelle's apartment, the doorbell rings. Michelle assumes it is the Chinese food they have ordered. As she walks to the door she picks up her wallet. When she answers the door and realizes it is not Chinese food but Mike, she slams the door and puts her wallet back down on the table. Before she re-opens the door to talk to Mike she has her wallet back in her hand and puts it back on the table, again.
Continuity mistake: When the truck hits the pot hole and splashes Ben and Andie with water, Ben's shirt changes from being semi wet to almost totally wet when the camera angle changes.
Continuity mistake: When Andie and Ben leave the first game of the NBA finals and Andie is climbing into the cab, she is holding the cup of Diet Coke and hands it to Ben. In the next shot Ben is holding the cup. Then in the next shot Andie is holding the cup yet again and in the other hand and hands it to Ben yet again.
Plot hole: The scene where Andie comes over for dinner and moves a bunch of frilly stuff into the bathroom, happens at least one day before she comes over with the wedding album she made. In that scene, Ben goes into the bathroom to splash water on his face and discovers the pink hand towel and other stuff - that means he would not have gone into his bathroom for at least a day, or two, since she put the stuff in there, or he would have noticed it sooner.
Continuity mistake: At the beginning of the movie when Ben and Andie have met for the first time and they are outside of the restaurant, Ben gives her the 'goofy' helmet he threads the strap through the clip only once, in the next shot it is threaded perfectly in the clip to fasten the helmet.
Continuity mistake: In the scene where Ben makes the lamb with cherry glaze for Andie, he is about to put carrots on Andie's plate when she says she is a vegetarian; you can see him drop the carrots back on his serving dish. When Andie makes him take the plate away before she gags, there are carrots on her plate.
Continuity mistake: Ben stops his motorcycle in the traffic jam waiting for the light to change. The camera angle changes and he's seen taking off but it's not in the same place he stopped to wait for the light.
Continuity mistake: During a card game, somebody drinks a beer. The tag changes between shots.
Factual error: When the 3 guys are trying to think of a slogan for the new diamond gig, Matthew McConaughey (Ben) suggests that they go play a game of 9 Ball to clear their minds. However, he racks up every ball in the triangle, which means they would now be playing 8 Ball.
Continuity mistake: On the night Ben and Andy meet they go and eat lobster, first the Andy's hair is behind her shoulder then it is in front, etc.
Continuity mistake: When Ben goes to get Andie a diet coke during the Knicks game the amount of soda in the cup keeps changing.
