Other mistake: When Paul Blart is pwning Rock Band, the vocals shows the tambourine/clap notes. Paul Blart is doing nothing that would play those notes (singing or pressing the "a" button).
Other mistake: When the mayor is talking behind the chainlink fence, with Brent in the background eating sardines, you can see as the mayor grabs the fence, his thumbs clip through the fence wire. This occurs on both hands and easily visible, particularly when Mayor Shelbourne says, "Otherwise, I'm just a tiny mayor of a tiny town full of tiny sardine-sucking knuckle-scrapers." (00:10:52)
Suggested correction: This isn't really what happens, although it looks like it does. The mayor's thumbs are not pointing outwards, they are curled around the fence wire. As he continues to grab the fence, his thumbs don't clip through it, they curl more and more around it, getting a tighter grip on it. Then when Brent says, "But not me, right?", he lets go, and you can see his thumbs curl back out. This is all visible if you look close enough.
Other mistake: When The Chipettes perform their audition for Ian Hawke they are standing on the Jett Records sign on the roof of the Jett Records building. In order for the sign to read correctly from the street, Ian and The Chipettes should have a backwards view of the lettering. In the movie the sign reads correctly from Ian and The Chipettes point of view, meaning that it is giving a backwards view to the street, ie. it is the wrong way round.
Other mistake: Charlotte's dad buys a newspaper in the beginning of the film. The same two paragraphs about Prince Naveen are repeated all over the front page, including under the headline 'Annual Goosenhoper State Gumbo Faire Is Smashing Success.' (00:08:45)
Other mistake: When Tinker Bell constructs a boat with the playing cards paddle wheel, she uses a clip and a rope to make sure the paddle wheel doesn't start turning. However the rope would only work at stopping the rotation if the wheel turned backwards. Since it turns forward, the rope shouldn't be able to stop the rotation.
Other mistake: The Spanish version has all the titles and signs changed to Spanish text as we can see when Carl opens the photo album. However, a side angle shows the letters 'O' and 'D' revealing it's the original English text, "Things To do."
Other mistake: In the classroom, during a travelling under the desks, you can see the girl blinker in the back, blinking.
Other mistake: When Rebecca gets back to New York, the cab she's in drives past a couple of billboards, advertising Disney's "G-Force", and the upcoming Bruckheimer produced "Prince of Persia". The billboards were reflected in the window of the cab in perfectly clear focus and correctly as the eye would see, not backwards as they should be as a reflection. (00:53:05)
Other mistake: After the Santa Buddies arrive and sing at Santa's workshop, it shows the town's Christmas tree magically light up and the sheriff runs out of and around the building to see it. There is freshly fallen snow, but no foot prints from him, or paw prints from the sheriff dog. (01:05:40)
Other mistake: Inspector Clouseau concludes Miss Solandres was the thief by looking at her license plate and discovering he gave the car a fine 2 days before she claimed to have arrived in Paris, 1 day before the Pink Panther was stolen. However she told Clouseau her car was a rental moments earlier, therefore he should've assumed the fine applied to the previous renter as Clouseau had no reason to doubt Miss Solandres' story at that point.
