Continuity mistake: Before the school bell rings, Jason asks Ms. Darbus for her favorite summer memory. When everyone turns to look at him in the shot from the front of the class, there is a book under Troy's desk, which is not there in the previous or following shots. (00:01:25)
Continuity mistake: In the scene where the security guard halts Mr Bean (dressed as a grandma) and the supposed kidnapped child, he is asked for his pass. Mr Bean hands the guard an already opened ID style flip card, but when the guard takes it, he is seen opening it as if it were closed.
Continuity mistake: Once the chipmunks are inside the food cupboards, they begin to devour everything inside. Theodore is seen chewing off a corner of a box of Lucky Charms cereal and eating the cereal that pours from the hole.

Factual error: In the final standoff, Smith shoots Hertz by holding cartridges between his fingers in the fire. This is not remotely believable. The casings, weighing much less than the bullets, would have been blasted off while the bullets themselves would have gone nowhere. (01:15:15)
Revealing mistake: Underdog's first costume is supposed to be a felted down (the more accurate term would be fulled) wool sweater. When wool is felted the stitches lose clear definition and usually achieve a "felted" look. It is clear that the sweater in the movie has just been switched for another smaller sweater as the stitches are still sharply defined after it has been pulled from the dryer. This is especially clear around the U. No attempt to make the smaller sweater look "felted" was made. This refers to the original costume with the solid white U, not the second costume with the yellow outlined U.
Continuity mistake: When Joe gets injured and he insists the back-up quarterback goes in, he takes his wristband with all the plays on it off, so it can be given to the back-up. When the back-up quarterback is shown running on the field, he does not have it on, but when they show the back-up on the field, he does have the plays wristband on.
Continuity mistake: As Juno is walking into the abortion clinic, an exterior shot shows that there is only one entrance door. The shot of her entering from inside the clinic shows a double-door entrance. (00:17:50)

Visible crew/equipment: The first time Candy enters the house, John waves to the guy across the street. Whilst he's doing this, you can see a reflection of the crew in the front door window.
Continuity mistake: When Chazz Michael Michaels goes to Katie Van Waldenberg to "comfort" each other Chazz leaves the door slightly open. Then it has a shot of Katie then back to Chazz and the door is completely closed. Then right before Jimmy walks in it shows a shot of Chazz and the door and it is slightly open again.
Continuity mistake: When Snow White rips off her sleeves she has a tattoo on her right shoulder. Later, when she calls the animals to attack the guards, the tattoo is gone.
