Other mistake: The dead blonde whose "throat was slit" is shown up-close twice (once in real time and once in a crime photo) and her neck is unharmed, with blood only underneath her head.
Other mistake: In his search of Giselle, when Edward knocks on doors 209 (hissing cat), 405 (barking dog), and 714 (purple guy), the funny thing is that in all three close-ups the three door jambs/trim have the same paint glob markings. The actual doors were changed, but the jamb/trim remained the same for all three shots. (Only visible on widescreen DVD). (01:04:05)
Other mistake: The subtitles say "Lloyd" when Norbit is talking to the dog but the credits say "Floyd". (01:09:20 - 01:34:00)
Other mistake: In one shot, a man is leaning over Feng and speaking in Chinese to him. The woman sitting next to Feng translates and says that it means the man has to go to the bathroom. Feng explains where it is and sits down. After, it switches shots to show the man leaving Feng's "throne" in the backround and sitting down, not going to the bathroom.
Other mistake: When Jenna was having her ultrasound, the doctor picked up a linear probe. This probe is only used for vascular purposes (arteries, veins) and cannot go deep enough to show an unborn baby. It also produces a rectangular image on the screen. The doctor should have used a curved probe which produces a curved image on the screen, which is exactly what was shown in the next shot.
Other mistake: There's a scene at the end of the movie where Annie is sitting looking through some graduate school brochures, and her boyfriend Hayden comes over and hands her a letter from the "5th Avenue Mom" she used to work for. She says she can't read it so he offers to read it to her. The camera shows a close-up of the letter as Hayden starts to read. In the letter it's written that it's been "some time" since we've spoken, but he reads it as "several months."
Other mistake: During the "Come Together" sequence when all of the business men have their big dance number, if you look to the right closely, one of the business men trips.
Other mistake: At the end, during the neighborhood fight scene, Monty is punching Joe, but you can clearly see that he is not actually coming in contact with Joe's face.

Other mistake: In the scene where you first see Tracy in class, one of the boys speaks and the subtitles reads," Ms. Whimsy, I can't see the board again." When Tracy says it, the subtitle reads Wimsey.
Other mistake: In the scene in the beginning when Chazz Michael Michaels is being introduced, there is a brief shot where Chazz is alone skating in the same storage where, much later in the movie, Jimmy and Chazz practice for the World Wintersport Championship.
Other mistake: Just before Debbie takes her shirt off after Walter has given all of the Playpen girls suggestions, one of the girls says "It's hot in here." (probably Debbie, but it doesn't really sound like her), but Mona doesn't start having an orgasm, when "in" is supposed to start it. (00:33:50)
Other mistake: When Henry and Lefroy strip off before going swimming, they enter the water wearing their boots, however their trousers have been removed despite there not having been time for them to remove them and replace the boots.

Other mistake: When Chuck is driving Cam to get her spare set of keys you can see it is dark out and the car has its headlights on, but the taillights are out. (00:25:50)
