Audio problem: On the beach Colonel Kilgore takes the radio phone from one of his soldiers and calls in the napalm attack on Vin Din Dop. If you look closely at his lips they do not go along with what he's saying. This happens again two shots later when he sends the Vietnamese woman and her baby to the hospital by helicopter.

Audio problem: Approaching Kurtz' compound Lance starts drumming on two tin cans and if you listen closely they get the overdub wrong. At first we hear two distinct pitches, which are the actual sounds, picked up by the microphone but the last time he hits it we hear a third higher pitch which was overdubbed. There are only two cans not three and he doesn't change the way he's holding them therefore you can only have a maximum of two audible pitches. (02:29:05)????
Audio problem: On the French plantation dock Captain Willard walks over towards the Frenchman and they do an excellent job of overdubbing the sound of his helmet strap each time it hits his chest. Two shots later they don't put in the sound as the helmet strap hit's against his chest several more times. (01:58:00)????
Audio problem: On the French plantation dock Lance picks up what looks like the sole of an old shoe and smells it. If you look closely you hear a sniffing sound that isn't in sync with the movement of his chest because he doesn't really inhale while that horrible thing is near his nose. (01:57:05)????
Audio problem: On the boat while reading Kurtz' file Captain Willard narrates to himself, "dear son, I am afraid that both you and your mother well have been worried at not hearing from me during the past weeks, but my situation here has become a difficult one". At this point they show the actual letter that he's reading from and the text of the letter is not the same as what we are hearing. (01:20:40)????
