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: Robin's minstrel's hand doesn't hit his tambourine the first time we hear them sing.
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: After the scene where the men had to fight off the giant bugs, there is a wide shot where the men can be seen being helped out of the pit by the captain and a few extra crewmembers. The captain is shouting something, however, if you look closely, his mouth is not in sync with what he is saying.
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.
Audio problem: In the end of the movie, after Lara and the gang get in the Jeep, she drives off, turning sharply and you can hear the tires squeaking, as if they are on pavement.
Audio problem: When Timon and Pumbaa awake from their first dream home by the rocks, they look up to see the animals towering and singing "I just can't wait to be king", but their mouths don't match the words of the song. They are actually out of sync by a few seconds because in the first Lion King movie the chorus was already sung at this point.
Audio problem: Just before midnight when the band is playing "Morning After" the camera pans out for a wide shot of the dance floor - the dancers are dancing MUCH too fast for such a slow song - and you do still hear the song.
