Audio problem: More than once Gracie or a member of her entourage is seen watching the distant pirate ship battle from the hotel window. The cannons fire and the blast is heard immediately. In fact, at that range (several thousand feet) there would be a discernable interval between the muzzle flash and the arrival of the weapon report.
Audio problem: When Meggett flirts with the cheerleaders by saying, "Call me," his voice is heard before the video shows him uttering the words. (01:05:30)
Audio problem: In the end of the movie, when Ben is found by two Swedish backpackers, the subtitles doesn't match with what the the woman is saying. The subtitles say something like "Come on, lets get him out of here", when in fact she says "Herregud hur kom han hit?", which roughly translates as "Oh my god, how did he get here?"
Audio problem: In the scene where Christina Milian is auditioning for John Travolta and Uma Thurman, it is painfully obvious that the audio for her song was pre-recorded. Her voice sounds distant, as if it were miles away.
Audio problem: Just after the long continuous fight scene in the restaurant, one girl pulls out a knife to attack Tony Jaa. The knife makes a sound like it's being pulled from a sheath but it's not touching any other metal.
Audio problem: Notice when anything heavy hits the bottom of the ocean it makes a loud thud. The bottom is soft sand and wouldn't make noise.
Audio problem: When Bovver is helping Pete up on the beach, Pete says, "My mate Bovver, never could turn down a good scrap," but his mouth never moves.
Audio problem: After Bruce and Rachel kiss, Rachel says, "But maybe he's still out there somewhere". Her head is seen from behind, but you can see from the motion of her jaw that her mouth is moving before the words are heard. (02:02:35)
Audio problem: During the opening credits, when the bullet's in the factory, the box in front gets a lid put on and then nailed. The box the bullet is in gets a lid on but no hammering is heard, so all the bullets would have fallen off when the box was loaded off the belt.
Audio problem: Charlie takes Darius to the big mansion; Ice Cube says "Woah woah woah wait a minute; this is your home?", but his lips don't move. (00:40:30)
Audio problem: When Dwight deduces that there is a spy among the girls in Old Town, there is a noticeable shift in the audio when he says "But first we gotta get our hands on Jackie Boy's head before it gets to wherever it's going and this whole situation blows wide open." The last three words of the line sound like they were re-dubbed.
Audio problem: In the scene when Grandma is at the tournament (but not yet skiing), in the cuts when the band isn't visible, if you listen closely, the lead singer isn't singing. (01:05:05)
