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: 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 "Candyman" song near the beginning of the movie, the candy store owner is on a ladder, about to drop candy into the kids' hands. When we see the kids holding up their hands and saying, "Me. Me.", none of their mouths are actually saying anything. (00:04:00)
Audio problem: When Bud is yelling at his sister in the school hallway by her locker, she complains about girls not being happy in poodle skirts and sweater sets. When the camera's point of view switches, her mouth is still moving even though she's stopped talking. (00:37:00)
Audio problem: When the elves are marching around, listen to the footstep sounds and watch their feet. A lot of times the noise and movements don't match. This is especially apparent when the five elves who have been taking wish calls go to the transporter.
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: When Tony goes down to help Rudoplh after he tries to fly out of the window, Tony asks him if he's okay and you can hear Rudoplh saying "Do I look it?" but his lips never move.
Audio problem: When Philippe climbs up to the grating in the church, a little girl talks to him, but her mouth does not move.
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: At the start of the movie when Shao Kahn and Raiden are fighting, Shao Kahn smashes Raiden into a pile of bricks. Then Shao Kahn says "You will never win". Watch when he says it because his mouth doesn't move.
