Rank Title Mistake
1 Jurassic Park III After the aeroplane crashed, a dinosaur stepped over it and the windows shattered making the typical sound of made-of-glass things when broken. I can tell everybody (I'm a pilot) it is not accurate because they are made of plexiglass (a sort of fibrous plastic).
2 Scream When Sidney comes running to the house and she sees Dewey come out with the knife in his back she screams "Dewey!" but her mouth says "no!"
3 Meet the Parents When Focker is going back to Chicago the woman who is typing stops moving her hands for a little while the clicking noise is still going.
4 Star Wars: Episode II - Attack of the Clones The aliens that populate the planet of Geonosis have an extremely peculiar method of speech - consisting of clicks and weird ringing sounds. However, despite the fact that they make up 99.9% of the crowd in the arena, the sound of the crowd cheering is human.
5 Legally Blonde In the scene after Reese Witherspoon and Luke Wilson are returning from questioning the ex-wife of the murder victim at a spa, they are driving up in Luke's car. You can clearly see, as they get closer to the camera, that what you hear Luke saying isn't what his lips are saying. It was a very obvious dub over...and a very bad one.
6 Selena When Chris drives up in the truck while Selena is mowing the lawn, Selena asks what he got. While you hear "junk food" his mouth says something else.
7 The Wizard of Oz At the very end of, "We Welcome You to Munchkin Land," at the very last 'fa la la la la laaaaaa' right before the Wicked Witch interrupts the song with her explosive arrival, you can hear someone scream before the explosion even occurs.
8 Meet the Spartans When Britney Spears gets pushed into the Pit of Death, you hear her talk and scream but her lips are not moving.
9 Harry Potter and the Philosopher's Stone When the troll is about to swing at Harry for the third time with his club, Ron levitates his club in mid-air. When the club falls, it hits the trolls head with a loud thunk, then falls to the ground. But you never hear any sound of the club hitting the ground.
10 Star Wars When Vader is talking to an Imperial officer in the hangar in the Death Star, when the officer says, "It must be a decoy, sir. Several of the escape pods have been jettisoned." his head is shown from behind, but his profile shows his mouth is moving before the words are heard.
11 Men in Black When Will Smith is looking at the two space ships at the MIB headquarters, if you look in the background Zed and K are there typing on the computer. But if you look closer you can tell that they're not even touching the keyboard and the sounds are just added into the movie.
12 Ace Ventura: Pet Detective At the beginning, when they steal the dolphin, you hear the peel-out sound effect as if the truck was on a paved road, but they were on grass.
13 The Matrix In the lobby shootout scene, when Trinity starts kicking one of the guards after he goes to reload and reaches for a new clip, you can hear her yell the first time she kicks him, but the next two times, although her mouth opens the same way, the audio's been silenced.
14 Big Momma's House 2 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.
15 Grease During "We go together" at the end of Grease, John Travolta's mouth is not in sync with the words.
16 The Terminator When the Terminator breaks into the police station, he has an auto-shotgun in his left hand, and a machine gun in his right. Before he kills the power in the building, he comes to the end of a hall, points his shotgun through a doorway, and shoots. A machine gun sound is used for the blast, instead of a shotgun sound.
17 The Notebook In one of the beginning scenes, when Noah and Fin are at the fair, you see Allie and Sarah on the bumper cars. Allie bumps into Sarah, and you can see and hear Sarah yell "Rachel," which is actually the name of the actress who plays Allie - Rachel McAdams.
18 Blade Runner Deckard (Harrison Ford) investigates the maker of artificial reptiles; an Abdul somebody. It's obvious that the dialogue was added as neither actor is in sync with the sound. The end of the scene has the storekeepers voice telling Deckard the information he was seeking while Deckard's mouth is the one moving. Deckard's mouth continues to move even after Abdul's lines are finished and the scene cuts.
19 Apocalypse Now As Playmate of the Year Carrie Foster is brought out to the audience carried by two Green Berets watch the band behind her closely. The bass player stops playing as he scratches his head but the bass on the soundtrack keeps going.

26 West Side Story During the opening overture, right when the orchestra starts "Maria", you can hear someone sneeze in the background. It's easier to hear on the soundtrack but you still can hear it in the movie.
27 Slither Just after the car crash, when the zombies are taking Starla, Bill and Kylie yell after her, but they call her Carla.
28 Independence Day When the Knights deploy their missiles with no results, we see in close-ups as they respond that Steven is Knight 1, Jimmy is Knight 7, and another Marine is Knight 3. After Steven says, "Knight 1. Sweet Luck. Echo, Fox 2," we <b>see</b> a close-up of Knight 3 and hear <b>his</b> voice (not Jimmy's) say, "Knight 7, Fox 2", though he is in fact Knight 3, and Jimmy is Knight 7."
29 Eegah After Roxy, Tom, and Robert discover Eegah's footprint, Robert can be heard saying, "Watch out for snakes!" however his mouth does not move at all.
30 The Lizzie McGuire Movie When Lizzie is performing at the end of the movie at the awards show, at the part where we see her from the back facing the blue light, her voice sounds like it's changing. It seems like it's someone much older singing, or the synthesizer went wrong. It just obviously isn't Lizzie's voice anymore.
