Audio problem: When the country music singer tells Parker that Elvis can sing his songs "but no wiggle" there's a side shot of his face and his mouth doesn't match what he's saying.
Audio problem: When Lionel tells the others to lift the button at the center of the compass, you can notice that the music box is still playing, but the drum of the machine is still. (00:08:30)
Audio problem: When Ritchie tells Sam, "I'm coming with you," right before they leave the bowling alley, Ritchie's line seems strangely dubbed in. It just doesn't quite match his lip movements for the first half.
Audio problem: In a flashback scene after Anthony says, " It is normal to be a little nervous" and Malia asks, "Is it?", Malia's mouth does not move when she finishes her question, "more rational to be paranoid or careless?" (00:47:13)
Audio problem: When Trevor is explaining to Riley how he wants to rob the storage unit, at one point there's an over-the-shoulder shot where he says "Totally anonymous... nobody's ever seen any one in there... but, like the shit..." If you look closely, you can tell Trevor is saying something completely different. True, his mouth isn't on-screen the whole time, but his jaw movements and his mouth movements don't match the words at all when they are visible, revealing they altered the dialogue in post.
Audio problem: The baddie enters the room with the two ladies and fires a shot in the air. He is holding a revolver but the empty casing can be heard hitting the floor as if the pistol was magazine fed. (00:39:00)
Audio problem: When Baldacci shoots the van that is coming at him full force, the sound bits inserted are of bullets hitting metal. Since he is aiming at the windshield, either his gun does not shoot straight or someone has been very lazy with the sound editing; even if he hit bulletproof glass, the sound it would make would not be like that at all. And a few seconds later his colleague shoots at the van from the side and there is no bullet impact sound at all; to Miss a static target of THAT size from a few feet of distance she'd have to blind as well. (00:43:05)
Audio problem: Katherine visits Poirot at the field hospital; the opening line has a loud gulping, most likely dubbed, and then Branagh's voice says "I asked you...not to come" with the second part of the sentence added in dub; his lips don't move. (00:05:45)
Audio problem: There was no sound during the time the scientist was giving his several-word response to, "Do you want a coffee?" (00:16:25)
Audio problem: When the boy and the leader of Iceland are hammering in posts and the boy is complaining that he's the heir and shouldn't have to do manual labor, there are at least two times when bad wind flutter in the microphones can be heard. It sounds like the wind clips the volume level and the audio briefly cuts out. It happens on windy film shoots, as wind screens can only prevent so much and its obviously very windy in this scene. Why this wasn't caught in post is hard to say. This is audible on the video on demand version.
Suggested correction: No such problem exists on the UHD/Blu-ray release. I also did not notice it on the VOD release, so it could have just been an issue with your sound setup.
