Other mistake: Near the end of the movie, Juni watches the start of the Floop's Foogles show. Yet the clock on the TV showed out the time to be 10:15 - 10:20.
Other mistake: Stifler, Finch, Oz and Jim all have radios. Stifler says during the lesbian scene that they are getting naked. This should have been heard on Jim's radio (he is under the bed), but it is not. We never see Jim turn his radio off as his hands are in shot. (00:43:20)
Suggested correction: It's a bit of a stretch, but maybe Jim had the wherewithal to turn it off (on or offscreen) simply as his radio is most likely to be overheard by the girls themselves, as he Is under their bed (or it malfunctioned somehow, was damaged in the course of all that scrambling about).
Other mistake: During the scene when Nelson takes Sara home after rescuing the puppies, she asks him in for coffee and he doesn't accept. After she tells him she will accept a ride the next morning, he agrees and turns off his car. One of his headlights does not turn off.
Other mistake: When Bev and Jason are on their way to visit Ray to get the form signed, they stop at a diner. Jason uses the phone to call Amelia and Bev orders 2 black coffees to go. After she leaves the bathroom and Jason hangs up the phone, Bev walks out the door and says "Jason are you coming?" and Jason grabs the coffees, but neither of them ever pay for them. (01:34:24)
Other mistake: After the failed marriage between Jo and Jack, there is a shot of a cliff. Notice that the clouds moving overhead simply disappear into thin air.
Other mistake: During the scene where Thrax is talking to the other germs and viruses in the Zit and is pointing out things on the map of Frank, the word 'collarbone' is spelled wrong ('Collerbone'). (00:52:49)
Other mistake: Amelie only recorded a bit of the Tour de France. When you see it played on the glass man's VCR then there is a bit before she started recording that is being played.
Other mistake: When Spike is strolling through the city, at some point he walks by one of those posts pointing to various directions. One of the signs is written in cyrillic characters and, below, we can read the "English" translation: Ruccian Town.
Other mistake: When Marvin and Sgt. Sisk are driving in the squad car, Sgt. Sisk notices Rianna walking her dogs and attempts to pull the car over to the right alongside the curb, but is actually just sliding his hands across the steering wheel, not really turning the steering wheel.
Other mistake: In the courtroom scene near the end of the film, the Apple logo on the laptop is upside down.
Other mistake: Victor and Neil leave in the Rally STX van to take the boys to Moose River. Later, when Beth goes into town the license plate number is '566 241' on her Chevy pickup, but when Victor drops Neil and the boys off, we see their Rally STX has the same license plate number '566 241' as well. (00:30:40 - 00:36:40)
Other mistake: When Jack is using the chainsaw to dig Burt out of the Graboid, we do not see where he is cutting, but we do see sparks fly just before he stops and puts the saw down. The chainsaw angle does not match the sparks' direction.
Other mistake: The sign on the office of the safari business gives the name of Mick's retired business partner as Walter Riley. In the credits of the first two films the character's name is shown as Walter Reilly. (00:02:00)
Other mistake: While in the wooden structure in the trench, a close-up of Ciki's hands reveals that they are pristinely clean. Considering that he has been rummaging around in and out of the trench, and tending to his gunshot wound, his hands should appear at least dirty.
Other mistake: As Jason wrestles around with the kid on his back his left eye opens some and his real eye can be seen. However, the eye was removed during the examination at the beginning.
Other mistake: The door of the plane is open and lets in a huge amount of pressure, but suddenly, a close-up of a corner of it shows how it softly closes tightly, without anyone turning its lever, or pushing.
Other mistake: The size of the town Jimmy lives in is inconsistent with the size of the population shown. The town is quite big if it has its own mall, amusement park, and a large elementary school. Yet combined with the kids and adults seen, there couldn't be more than a hundred people living in this town.
