Continuity mistake: Just before the warrior throws his spear at Chief Phillips there's a shot of Lance at the helm of the boat and we see the right side of the arrow in his hair pointing straight out and the left side pointing upward. In the previous shot both sides of the arrow were pointing straight out. (02:22:25)????
Continuity mistake: As Chef shows Chief Phillips and Clean the picture in his Playboy magazine of Miss December you can see the USO stage behind them. In the previous shot of the boat leaving one of the six tall lipstick statues on the upper left of the grandstand was knocked down. Now as the boat departs all six statues are standing.

Continuity mistake: As Captain Willard stands in front of him the shrunken head hanging off Lieutenant Colby's rifle is not this same one we saw several seconds ago when the captain first set eyes on him. The second one has thicker darker hair and is attached to the rifle differently. (02:33:00)????
Continuity mistake: After they leave the French plantation Chief Phillips maneuvers the boat through some thick fog and says, "I said I can't see a thing captain I'm stopping this boat, I ain't riskin' no more lives". When he says this line he's looking directly at Captain Willard but in the next shot his head is turned as he looks over towards his right. (02:20:15)????
Continuity mistake: As they begin to break out of the fog bank Chef says, "watch it over here, chief, got a stump". Here he's helping Chief Phillips steer the boat with a long pole that he places back on the floor of the boat after the uses it. You can see that it's not hanging over the right side of the boat behind Chief Philips but at the beginning of the arrow attack it's back extending out over the side. Then a few shots later as Captain Willard runs to the back of the boat to stop Chef from firing it's gone completely. (02:20:55)????
Continuity mistake: There have been many shots of the surfboards as they flew to Vin Din Dop and they were all on the skids of the helicopters, now when Colonel Kilgore says, "do you wanna surf, soldier" we see the surfboards placed next to each lengthwise through the helicopter with their fins sticking out the side doors. (00:46:05)????
Continuity mistake: Captain Willard shreds all of his notes on Colonel Kurtz and narrates to himself, "but the thing I felt the most, much stronger than fear, was the desire to confront him". In a wide shot of the boat we can see that the flag that covered Clean's body is back on top of the PBR. (02:26:20 - 02:27:50)????
