Audio problem: The scene where Bennet and Matrix are fighting towards the end of the movie, before Matrix kills Bennet they have each others throat in their hands and one of their backs is against the furnace. While they are grunting and groaning, if you listen carefully, you can hear one of them say "switch" just before they change positions.
Audio problem: When Matrix tells Cooke that "I eat Green Berets for breakfast" you never see his lips move when he says "But right now I'm very hungry."
Audio problem: When the soldiers surround the shack and finish firing at it,you can hear a shotgun blast last while nobody shot.
Audio problem: When Cooke starts up the Cadillac in the dealership you hear the engine turn over and fire twice.
Audio problem: When Arnie sets his stop watch to count down from 11hrs, each second that the watch ticks over there is a loud 'beep'. This is consistent with when he looks at his watch later in the mall, when it reads 9hrs 40mins to go, his watch is still beeping every second. Therefore, Arnie's watch should have been beeping every second of the movie in between these two scenes, but we never hear it. Also, when Arnie and Cindy arrive at the Sunspot Motel (7hrs 57min to go) and when Arnie's in the back of the police wagon, at 5hrs 2min to go, the watch no longer beeps with each passing second.
