Audio problem: When the cop saves the girl from the mob of locals, his car tires squeal as he accelerates away, but the car is on loose dirt, which makes the squealing impossible.
Audio problem: Before they leave for Mission City, Lennox tells Keller, "Sir, you gotta figure out some way to get word out..." Then in the next shot, as Lennox shouts, "Let's move!" his mouth stays open - not forming the "m" with his lips to produce the word "move", which we hear very clearly (it looks as if he really said, "Let's go!"). Changes in dialogue are done during ADR and often are not in sync with mouth movements seen onscreen. (01:45:45)
Audio problem: Just as McClane and Farrell are about to leave the Eastern Power Hub, Farrell goes on a long rant and his mouth does not match the words he is saying. [In the unrated version of the film, the rant concurs with Will's mouth movements, but the mistake is valid for the regular version.]
Audio problem: At the scene where Mikey asks the elder penguin if anyone surfs in Shiverpool, when he says,"You know you're standing on thin ice," his beak never moves.
Audio problem: When Dakota and Jerrod start having sex, Aubrey's mother can hear Jerrod's moans through the ceiling. But up until they *really* start getting into the act, the moans that Susan is hearing don't match the shots in the bedroom.
Audio problem: When Troy and Gabriella are singing "Everyday," Troy sings with his microphone away from his mouth numerous times during the scene, yet he is still heard just as well, and not at a lower level, like he should be. (Within the context of the film, this is sung live on stage and is not implied to be pre-recorded.)
Audio problem: During the scene where he is hitting golf balls off of the ship, he is hitting an iron. For anyone who plays golf, the sound that goes along with this is that of a driver or some type of fairway metal.
Audio problem: In the hospital, while discussing the list, Edward talks to Carter and, from the back, he says the word "grief" and the sound stops; but his jaw keeps on moving as if he kept on talking.
Audio problem: When Milly tells Jason about Johnny, Jason tells her, "If you want me to say it, I will stop seeing him," right after that he says something else, but there is no sound. Looks like a word starting with the letter F.
Audio problem: When John and Nedderman show up at Woodcock's ex-wife's house, and Nedderman is driving away, he tells John to ask if she has a pool, then a koi pond. Then he says, "Fish tank?" as he is driving away, but his lips are not moving.
Audio problem: When Ben and Jason are talking over the phone, after Jason tells Jonah, "Your mom is already there", we hear Jonah say, "Uncool man," but his lips are mouthing something different. (01:47:05)
Audio problem: In the scene where Doyle, Scarlett and the kids jump into the Volvo estate to escape the gas and infected, a number of references are made to the car having a manual gearbox, i.e. "pop the clutch". Doyle puts the car into second gear and several shots of the gear lever are shown. However, when Doyle push starts the car and they drive off, listen carefully and you will hear the distinct sound of the gear change of an automatic box.
Audio problem: When Damien Blade shows up at the end, he shows up on a motorcycle close to the crowd, right on the main road, yet there's no sounds of a motorcycle pulling up before hand. They would definitely have noticed him pull up and hear his motorcycle coming in way before he stepped off the bike and the crowd parted way.
Audio problem: When the number 8 soccer player says to the other soccer player, "Your mother is a chain smoking terrorist," his mouth isn't moving.
Audio problem: In the scene where Davey Jones is playing his organ, the sound is backwards to the way it should be. When he hits the lower notes, the sound emitted is actually *higher* than when he hits the higher notes.
Audio problem: When Luna and Harry converse, as she posts signs for her 'lost' belongings, in the overhead shot of her dangling sneakers she says, "If not always in the way we expect," but her lips are not moving. (02:01:45)
Audio problem: When Rasputia is hitting the crowbar in her hands the sound is out. (01:06:40)
Audio problem: When Angel is having a go at Danny in the rain after Tim Messenger has been murdered, there is a shot of Danny over Angel's shoulder. In this shot you can see Angel's mouth isn't moving, but we hear him still shouting at Danny.
Audio problem: Harrison hears Ro's phone yet it's on silent mode.
Audio problem: Lois and Jimmy are snooping around in LexCorp and find a locked door. Jimmy goes to a panel and says "Great... Retinal scanner. Now what?" when he says "now what", the camera switches to an over the shoulder view, and his jaw is not moving when he says it. (00:56:40)
