Continuity mistake: When the dog leaps onto the cabinet, the contents inside fall out including the mop. The shot then switches to a ground shot showing more things fall. We see the mop fall again.
Continuity mistake: In the opening of the movie, when Rusty and Danny are flying back to visit Rueben, you see them boarding a Gulfstream G200. However, the interior shots actually show them flying in a Gulfstream 5 (probably the one on the ramp next to the G200 when they exit the aircraft).
Continuity mistake: When Ben and Gwen are fighting off aliens on Incarcecon, right after the tetramand destroys the hoverboard, the Omnitrix is missing from Ben's wrist.
Continuity mistake: In the study there is a large beige rug, which encompasses most of the room and has furniture on it, that moves farther away from the step up to the doorway as the scenes progress.
Continuity mistake: In the beginning of the movie, Rachel lies down in the shade of a billboard on the side of the road. When they cut to the wide shot the shadow of the billboard is on the opposite side so Rachel is in sunlight. This might have symbolized the passing of time, but in the next shot, when Harlen comes to wake her, she is in the shade again.
Continuity mistake: During the scene where Lewis is first on the roof-top, and Mildred comes up to speak with him, the box he is sitting next to is plain wood on one side, and tallied on the other. When there is a close-up of Lewis' legs and the torn paper, when he's ripping the pages out of his book, the box has stencilled writing that is upside down. (00:06:25 - 00:18:30)
Continuity mistake: During the love scene between Smith and Donna, when the killers first come in the door, Smith's pants keep changing from being down (while he is having sex with Donna) to up around his waist like normal as he rolls off of the bed.
Continuity mistake: When Michelle gives her pep talk to Coach Fields, the house they're in is the house they moved from at the beginning of the movie.
Continuity mistake: When Fred gets to the North Pole and the Security elves take him down. Fred comes up and the snow on his face change between shots.
Continuity mistake: In the hospital scene, when Jenna's close up shot is show her a strand of her hair alternates from being in her face to off her face to back in her face. (01:30:05)
Continuity mistake: Drew Barrymore's hair varies from shot to shot, as well as within scenes. It's always styled a bit differently, as if she did not have the same hairstylist more than once.
Continuity mistake: In the hybraxi, Al Gore's blazer is blue and he is wearing a red tie, but in the next shot, it is brown and he has no tie.
Continuity mistake: When being shot at by the angry waiter, the right hand door mirror was hit by the rifle shot. A few seconds later a view shows only a very minor hole in the glass, and no damage to the rest of the mirror. Surely a rifle shot would have caused more damage to plastic and chrome trim, almost surely passing right through. (00:30:20)
Continuity mistake: While Susan and Charlie are passing notes towards the beginning of the film, her cell phone (a Virgin Mobile endorsement plug) continues to flip from a lying down position to a propped up position on her desk between shots throughout the scene.
Continuity mistake: When Nikki and Kat are sitting on the floor in a secluded part of the library, there is a single book lying flat on the bottom shelf in front of them, with the binding facing out. In the next shot the book has changed position.
Continuity mistake: There's a scene in Kate's restaurant kitchen where Nick asks Zoe to hold the big bowl of spaghetti he had been eating, and she starts eating it. At one point there's a piece of basil hanging off the edge of the bowl and when the camera cuts back to her, it's gone.
Continuity mistake: Kim reminds Charlie that they already spent a lot of their savings on fixing up the house to handle more kids, but in the first movie they fixed up the old comic book store because they weren't allowed to watch more than 12 kids in their house by law. (00:08:25)
Continuity mistake: When Allison is swimming with her nieces and Ben, she is sitting at the edge of the pool and you can see her stomach is normal and toned, but in the scene prior she meets with the gynecologist and you can see she has a fairly big belly. (00:54:45)
Continuity mistake: After arriving at the mountain cabin, Terry comes in to the bedroom and notices Diane has fallen asleep while working. At first, her laptop computer is screen-up on her lap with the stylus in her hand. But just before Terry leaves, the laptop is screen-down and the stylus is gone.
Continuity mistake: When Johns parents come home early, there is a shot outside showing his parents set off down the path to the front door, then there are shots inside of everyone rushing to clear up before they get in. Then it goes back to an outside shot of his parents coming down the path, but they should have reached the front door already judging from the time of the shots inside.
