Audio problem: When Vader is talking to an Imperial officer in the hangar in the Death Star, when the officer says, "It must be a decoy, sir. Several of the escape pods have been jettisoned." his head is shown from behind, but his profile shows his mouth is moving before the words are heard. (01:03:55)
Audio problem: After Bond sets the timer on the bomb at the end, the ticks don't add up. There's a definite tick each second, and you can count 12 of them after he starts it, then we cut back to the bomb and only 7 seconds have passed. (As a vague trivia aside, coincidence though it is, on the UK DVD he pulls the pin out at the DVD second timer ticks onto "07").
Audio problem: Just before Toby closes his bedroom door while Roy and Ronnie are arguing, if you listen carefully you can faintly hear director Steven Spielberg telling him to close the door. (01:05:00)
Audio problem: After the bus crashes to a halt on the courthouse steps, the gunfire stops. A few seconds later, a bullet hole opens up on the side of the bus - but there is no sound.
Audio problem: The rock drummer is way out of sync with the drum sounds. Examples include fills, rolls, and cymbal crashes being performed when a straight beat is heard. (01:34:20)
Audio problem: The section of sound effects used as the Trans-Am and the big-rig pull up to the warehouse to get the beer is exactly the same 'loop' as the effects used when the Trans-Am and the big-rig stop by the pond to give 'Fred' his burgers for lunch. Specifically, the Trans-Am's engine idling down to a stop, then the T/A's door closing, then the big-rig's air brakes squealing a very distinctive sound and finally the big-rig's engine rattling to a stop. Exact same 'loop' both times.
Audio problem: In the scene where Bobby is talking to Tony's brother (the ex-priest) in the nightclub about getting his girlfriend pregnant, his lips rarely move when he is speaking, when the scene is shot on his right side. His movements of his mouth do not match the dialogue. (01:04:45)
Audio problem: During the scene where Lauren is talking to Wade on the phone and the car smashes through the window, she says she's hears the engine of the car, and that it "sounds so weird". Watch closely, though, and you'll see that the words aren't quite synchronized with the way her mouth moves. (I saw this on the VHS tape and the DVD).
Audio problem: In the initial narration, just after the voiceover mentions the gods and "protect men from their own weakness" you can see the singer moving his mouth without any voice being heard, and in the next shot the flute player peeking at the camera laughing to himself instead of playing - but the sound we hear is just perfect anyway. (00:02:00)
Audio problem: In a wide view of the mice singing "Rescue Aid Society" at the United Nations, a mouse is hitting his drum with a drumstick, but no sounds are coming out of it.
