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.
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: 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: There was no sound during the time the scientist was giving his several-word response to, "Do you want a coffee?" (00:16:25)
