Deliberate mistake: None of the helicopter's in the movie have the Army markings seen on Vietnam era Hueys. The most you'll see is some crooked, faint and inaccurate stencils in the wrong spots. (00:37:50 - 00:51:25)

????

Audio problem: Right when Captain Willard introduces himself to Colonel Kilgore, the audio track for the background battle sounds cuts out for few seconds. (00:27:20)

????

Continuity mistake: As Colonel Kilgore calls out to the soldiers surfing in the water Captain Willard's band-aid on his right cheek appears out of nowhere for the first time in the movie. He had no band-aid on his face before this and we don't see him put one on, and there's no indication from the last time we saw his face that his scar started to bleed. (00:47:00)

????

Continuity mistake: When Colonel Kilgore shows Lance the surf as they fly over the beach he says, "look, good six-foot swells" and his surf board is not on the side of his helicopter as it is in the next shot when they land. (00:45:10)

????

Continuity mistake: As they approached Vin Din Dop over the beach we see the bridge on the left and no sampans with red sails are there. Fifteen seconds later when they come around the other side of the bridge there are three sampans with red sails unfurled. (00:39:40)

????

Continuity mistake: Before Colonel Kilgore looks at Captain Willard and says, "Someday this war's gonna end," the Vietnamese women and the soldier waving behind him to his left have moved between shots. (00:49:45)

????

Visible crew/equipment: As they sit in the foxhole watching the surfers, Lance's helmet gets wet and you can see the reflection of two studio lights, and the crew standing between them, in it. (00:47:10)

????

Audio problem: Before they dock at the USO show at Hau Phat Chef says, "Jesus". He also says some other stuff that has been edited out. (01:04:00)

????

Audio problem: Just before the flare flies into Colonel Kilgore's helicopter, Lance says, "Nice shot, Bill" but his lips are not moving. (00:41:50)

????

Continuity mistake: When Colonel Kilgore talks to the men and says, "It smelled like victory," a line of sweat and dirt appears on the right side of his chest around his dog tags between shots. (00:49:45)

????

Continuity mistake: In some shots of the helicopters as they approach Vin Din Dop they're above the clouds, but in successive shots they're at or near ground level. (00:38:35)

????

Continuity mistake: In one shot we see the helicopters firing on the huts along the Vin Din Dop beach and the four missiles go directly into the beach nowhere near the huts. In the next shot the middle hut blows up. (00:40:00)

????

Other mistake: Kilgore watches from the beach after he calls in the napalm attack on Vin Din Dop. We see a large explosion but the three fighters never actually drop any napalm, they just fly over. (00:48:50)

????

Continuity mistake: As he looks towards the surfers, Colonel Kilgore says, "Lance, the wind, the wind" and it's quite overcast. Then in the next shot of the surfers the sun is out. This scene switches between close ups of Kilgore and the other men and the sun is out in the close-ups but not in the other shots. (00:50:10)

????

Continuity mistake: Right after the napalm explosion there's a wide shot of the beach as Colonel Kilgore and the two soldiers with him look across at the destruction. We also see Lance sitting alone in the crater and Captain Willard is nowhere near them. They cut away to the PBR for three seconds then back to the crater and the Captain is sitting next to Lance again. (00:48:55)

????

Visible crew/equipment: Kilgore points at the jets as they approach the tree line just before the napalm explosion. Look closely above Lance's head as some stage equipment makes a very quick appearance. (00:48:50)

????

Continuity mistake: Kilgore walks towards the beach and notices that the wind is starting to blow on shore and ruin the surf, and intense red green and yellow smoke canisters appear on his left between shots. (00:50:00)

????

Visible crew/equipment: In the shot of Captain Willard and Lance joking about the colonel Lance says, "how am I going to shoot him the next time he comes around?". Look closely between the two actors as an equipment shadow moves from left to right than back again against the trees behind them. (00:54:45)

????

Revealing mistake: In a close-up of Captain Willard's face as he reads about Kurtz' "Operation Archangel" the sweat droplets on the band-aid are exactly the same as the droplets on his skin. The droplets were obviously sprayed on his face as Band-aids don't sweat. (01:02:50)

????

Continuity mistake: As they start to eat with General Corman there's a hat hanging on a cabinet behind and to the right of the general and both doors are closed behind it. The next time we see it the right door of the cabinet has been opened but no one went near it. (00:11:45)
