Audio problem: As Playmate of the Year Carrie Foster is brought out to the audience carried by two Green Berets watch the band behind her closely. The bass player stops playing as he scratches his head but the bass on the soundtrack keeps going. (01:07:55)
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. (00:47:25)
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: Colonel Kilgore takes the megaphone and says to the surfers, "Okay give it a try guys, one goes left and one goes right "and his lips do not match what he says. In these several shots he's saying a lot more than what we hear. (00:50:50)
Audio problem: When Clean says that great line, "Well I'm next ma'am," to the Playboy bunny, he also says something else that was edited out. (01:32:50)

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: When they first meet Captain Willard asks Dennis Hopper who he is and he answers with a question, "Who are you?". If you look at the Captain's lips he answers the question but it was edited out. (02:29:55)

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)
Audio problem: After Captain Willard says, "They're just little sticks. They're just trying to scare us", Chief Phillips has some prime words that he shouts at the captain which are edited out. (02:22:05)
Audio problem: As Willard, Lance and Chef are approaching Kurtz's compound, Lance is playing come creepy sounds with 2 tin cans and a drumstick. The sounds do not match the number of times that he hits the cans nor coincide with when he hits them. (01:45:40)
