Other mistake: When Skinner calls his lawyer he never dials the phone.
Other mistake: When Leela is signing the petition, Amy grows a third arm for a split second.
Other mistake: In the sequence where Bo is taking his driving test, the driving instructor is shown fumbling to put on his seatbelt three times, all of which are from the same piece of film. (00:00:45 - 00:02:45)
Other mistake: After all the plants have stopped being pollenated when the pollen jocks are getting ready for liftoff you see the branches outside the window have green leaves.
Other mistake: When Homer drives through the barrier the second time (leaving the lake after dumping the silo) pay very close attention, his car smashes one portion of the barrier, but his car passes through a second portion of the barrier without breaking it. (00:23:50)
Other mistake: After Kelly and the twins climb out of the sewer tunnel and hear footsteps, the twins sit atop the steel grating pretending to cry while the rest hide below. All the walls and paintings behind the twins are the very same ones behind Kelly, Taylor and Andrea later, when they've finally reached their target painting, in a different area of the gallery. We can even see the square of wood planks covering the area of the steel grating seen earlier. (01:13:35 - 01:24:00)
Other mistake: When Sophie is babysitting her sister's kids, they show her playing a dance game. In one shot of the TV, you can see there is no arrows going up but she is still dancing. (00:17:30)
Other mistake: Near the end of the movie, an order is given to fire a cannon shot at the masts of the Pearl and the Dutchman as they have become entangled. We then see a mast being destroyed by the shot but when the ships separate, not one of them has a broken mast.
Other mistake: Being a three time mom, I know that the sonogram that Susanne gives Nick at the beginning could not be hers, due to the fact that she just found out she was pregnant. The babies on that sonogram are too detailed. They have to be at least 30-35 week-old fetuses. At her stage, you would not be able to make out the baby.
Other mistake: When the cleaning crew is leaving Joe's apartment, you can see a green Oreck commercial vacuum. The handle is on backwards.
Other mistake: Right at the beginning of the movie, when Lewis's real mum picks him up from the box and hugs him, it's no more than three seconds before she hears Lewis from the future slipping on the step. She gets scared and puts baby Lewis back in the box. When Wilbur takes Lewis to meet his mum, near the end of the movie, the time his mum holds the baby is more than twenty five seconds.
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: When Martin Freeman punches in the numbers on the telephone to call Steve Coogan, the numbers he enters are not shown on the telephone's screen.
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: The ink on the pad and the ink on the stamp that Fred marks the kids "nice" are wrong. If you look at it Fred doesn't hit all the colors in the pad. He only hits one color.
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: There's a scene where they turn a wheel to control the flow of water into a much larger chamber. The cavern that is presumably completely filled with water (water is dripping off the ceiling) is massive. The flow from the smaller chamber into the cavern is relatively small. They enter moments after stopping the flow to find the cavern is drained. It should A) either take the cavern a very long time to drain or B) the cavern should never have been fully filled with water.
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.
