Audio problem: At the end of the film, where Big Momma is performing with Carrie's cheer leading squad, when Andrew breaks loose and climbs up the human pyramid that the girls made, and jumps, falling on Big Momma's stomach. Then Andrew says, "Big Momma" but his mouth doesn't move.
Audio problem: Just after the car crash, when the zombies are taking Starla, Bill and Kylie yell after her, but they call her Carla.
Audio problem: Alexis confirms in a conversation with his brother that it's Valentine's day 2006, but if you watch his lips he says 2004.
Audio problem: Near the end when Drake is playing Hollywood Girl and gets into the bridge (the steady drum beat part) you can obviously tell he's mouthing the words.
Audio problem: In "What I've Been Looking For", when Sharpay sings the last verse the first time around, listen closely as Ryan takes away the microphone. Her voice remains the same volume, and does not get any quieter as Ryan pulls away the microphone.
Audio problem: When Andy is talking to Nigel during the photo shoot in the park, her mouth is not quite in sync with what we hear during her last line of dialogue, despite the people walking in front of her.
Audio problem: In the shot where the kids are locked in the police car, banging on the windows yelling at the policemen, their cries are muffled as if the car was totally closed up. As the camera zooms in, you can see the front driver's side window is open so the kids' voices should be much clearer.
Audio problem: In the scene inside the bar where Isabella is telling Crockett what happened to her mother (during the over-her-shoulder shot), her mouth doesn't match what we hear her saying.
Audio problem: When Doug is staring at the terrorist and says, "I can see him, he's right in front of me", you'll notice that his mouth moves a little before words are actually said. This is because he first says "Jesus", but they took it out because the character playing the terrorist is Jim Caviziel, who played Jesus in Passion of the Christ. The filmmakers did not want to get a laugh out of that line which it inevitably did in test screenings. (01:06:10)
Audio problem: When Scott is making a distraction, he says, "Well, this show stinks." But his mouth is saying, "Well, this show sucks." Done in order to keep the G rating, I presume.
Audio problem: When Jon and Liz are in the hotel room just after the animals make and eat lasagna, Liz giggles. However her mouth doesn't move to indicate that she giggles, proving that it was added in later. (00:48:40)
Audio problem: When Michael is caught in a traffic jam he shouts, "Will ya stop talking and fix the sewer". But if you look at the side view mirror, his mouth is not in sync with the words.
Audio problem: Everybody knows that waterfalls are very loud. However, in the scene at Hakoni Falls, which is completely surrounded by waterfalls, it's silent as a tomb.
Audio problem: Before the Tortuga bar brawl the musicians are shown playing their instruments. When Elizabeth says, "I just wanted to have the pleasure of doing that myself," it is quiet in the bar, but the violinist is seen happily playing directly behind her and no sound is heard. (01:08:20)
Audio problem: Rocky is trying to convince Marie to work at his restaurant, outside of her apartment. The close up shot of him talking about a bus coming down the street and hitting him does not match his mouth movements, when they go to a long shot.
Audio problem: In the scene where the guys are looking at Olivia, talking about her nodding at Sebastian, Sebastian says something, then his phone rings. He continues mouthing something over the ringtone, but no sound is heard.
Audio problem: When Hilary Duff is in prison with the three ladies, she asks for something grainy to remove the make-up the women are wearing. The large lady says that she has an "egg roll or bagel in the bar" and to just give her a minute. But if you look closely at the lips, she says something else as to where the product is hidden.
Audio problem: When they first enter the building they are going to use for the fake school, Bartleby tries to put a board back in the ceiling, and a body falls to the ground. Schrader screams, but the scream is heard before he actually opens his mouth. You don't see his mouth open until the camera pans into his character, but the scream is audible about a half-second before the camera movement.
Audio problem: When Joanne is pulling out her bra strap, the song that is playing hits a line with the words, "If we're f***ed up, you're to blame (but it actually says the whole word). Whenever the song hits that line again, the word is entirely censored.
Audio problem: The source music in the ballroom does not match the Poseidon orchestra's motions.
