Audio problem: When they scream at the cupcake shop, Gru sounds like he's behind the glass dome, while Lucy gives off a regular scream. But as we can see, Lucy is behind the dome, making a silly face, not Gru.
Audio problem: During the Walmart scene, it seems they edited in Gary saying "Oh, God." However, it's over no visible mouth or throat movements. (01:15:17)
Audio problem: In the scene where the Prince meets up with Leonardo da Vinci for the first time and notices that his guards have found him, he says 'Oh, I can't believe this'. His mouth isn't in sync with what he's saying.
Suggested correction: Firstly, the closed captioning reads, "God, I don't believe this." Second, Henry actually says it twice - the first time his mouth IS in sync with what we hear, but then he mouths under his breath "I don't believe this," again, in annoyance with the situation.
I am watching the scene right now, and his mouth really isn't in sync. In order for him to say the word "believe" (even in mumbled form), he would have to move his mouth to form the "b" sound, and he does not at that point.
Audio problem: The carts the guards are chasing Pee-Wee in are electric, which we see when they first get to them and have to unplug them. However throughout the entire chase scene we distinctly hear gas engine sounds. (01:12:30)

Audio problem: When Spiller throws the rope in the milk bottle trying to pull Peagreen out, you can hear him straining and grunting to keep a hold of it but his face and mouth are both relaxed.
Audio problem: The chairman talks to the mayor, and says that "no one supports you." When he says "supports", his lips look nothing like it.
Audio problem: When Hynkel refers to the peace treaty and says "I'll sign it," you can hear the sound quality change abruptly, and when Hynkel is saying "Napoloni the grosse peanut, the cheesy ravioli," his lips are not in sync.
Audio problem: As they are running away in the ice cream truck, Ed turns on the jingle and starts dancing. Dexter gets annoyed and turns the jingle off, but the music stops about a second before he hits the button.
Audio problem: In the Final Jam scene, when Mitchie is singing the lines "Every day and every night, it's all we want to do in life," Caitlin and Shane can be seen mouthing "We rock, we rock, we rock," in the background, but it is not actually being sung. (01:32:05)
Audio problem: When Sarge is giving instructions to Allbright over the taxi radio Allbright replies "I don't know what the union's going to say about all this" to which Sarge replies "**** the union". His mouth doesn't open while the noise sounds to cover up his swear word.
Audio problem: At Thomas J's memorial service, Vada goes up to the coffin crying. Just after she says something about his glasses being missing, her father comes up to comfort her. Watch his mouth - he is heard talking but his lips aren't moving at first (they are in the next shot).
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 Janis shouts at Cady out of Damian's car, Cady says "It's not my fault you're like in love with me, or something." After she says this, her mouth visibly moves saying more words, but no audio is heard. (00:58:40)

Audio problem: In the beginning of the movie when Clark is preparing to light the Bar-B-Q, He squirts charcoal fluid out of a plastic bottle. Then Ellen squirts more fluid onto the coals out of the same plastic bottle. Listen to the sound; it is the distinctive sound of a metal charcoal lighter fluid bottle. (00:07:45)
Audio problem: During the football match when Forrest runs and bumps into the band players, we hear what sounds like cymbals crashing/dropping to the ground. But if you look at the band players he knocks over, there are no cymbals anywhere near them.
Audio problem: When Rocco is testing the bomb in the morning in the cabin, when he says, "We're going to detonate it", his mouth isn't moving with the words. (00:50:35)
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: In the public restroom fight, Arnold slams one of the bad guys head into the ceramic urinal. Although you hear two loud and clear "klonks", the urinal bends when Arnold presses the bad guy's head down. [Only visible in the pan and scan version.] (00:31:55)
