Audio problem: When the Knights deploy their missiles with no results, we see in close-ups as they respond that Steven is Knight 1, Jimmy is Knight 7, and another Marine is Knight 3. After Steven says, "Knight 1. Sweet Luck. Echo, Fox 2," we see a close-up of Knight 3 and hear his voice (not Jimmy's) say, "Knight 7, Fox 2", though he is in fact Knight 3, and Jimmy is Knight 7.

Audio problem: After David's rant about burning the rainforests, etc, when he's on the ground Julius takes the bottle out of David's hand and we hear the sound of the bottle hitting the floor. But Julius still has the bottle in his hand, then puts it down two shots later - with no sound obviously. (01:35:30)
Audio problem: The same female scream can be heard three times during the first attack by the aliens. It is first heard in the scene when Jeff Goldblum is riding his bike to his father's house. The second time it is heard right as Jeff gets to his father's door. The third time is in Los Angeles when the people are running away. It's a very distinct scream.
