Continuity mistake: After Chief Phillips falls to the floor of the boat Captain Willard kneels down to try to help him. Look closely at Phillips' left hand, there's blood dripping on his knuckle. In the next shot when he grabs the captain around the throat there is no blood on his left hand. (02:23:05)

????

Continuity mistake: During the arrow attack as Chef is firing the rear machine madly Captain Willard walks from the front to the rear of the boat to try to stop him. Just as he swings into the back part of the boat he slips and falls backwards. In the next shot he's up and running toward Chef. (02:21:50)

????

Continuity mistake: After Colonel Kilgore looks at Captain Willard and says, "someday this war's gonna end" he gets up to walk away and the soldier to his right straps his rifle around his right shoulder twice between shots. (00:49:55)

????

Continuity mistake: During the arrow attack as Captain Willard grabs Chief Phillips to try and make him stop shooting, the sun can be seen setting over his shoulder. Several other shots in this scene, like the next one, were filmed in the mid afternoon with the sun overhead. (02:22:20)

????

Continuity mistake: As the helicopters land in Vin Drin Dop "The Ride of the Valkyries" is still playing but none of the helicopters have speakers hanging out of their side doors to play the music the way they did before. (00:42:30)

????

Continuity mistake: As they all sit on the boat and listen to the "Arc light" B-52 strike Lance is sunbathing in direct sunlight. In the next shot he's in the shadow of the roof of the boat as he gets up and says "there they are". (00:24:15)

????

Continuity mistake: As Chief Phillips is speared he holds on to the roof of the boat with his left hand. The straw has been rearranged from previous shots and is no longer hanging over the side of the roof as it was in the shot before. (02:22:35)

????

Continuity mistake: One minute into the attack on Vin Din Dop one of the helicopters flies over the schoolyard. This aerial shot is taken around mid-day as there are no shadows visible in schoolyard, unlike the first shot of the schoolyard at the beginning of this scene, which was done when the shadows were long. (00:40:20)

????

Continuity mistake: As the boat approaches Kurtz' compound the natives in the canoes are looking forward. In the next shot they're facing sideways looking at the PBR. (02:28:15)

????

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)

????

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)

????

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)

????

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)

????

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)
