Continuity mistake: As Captain Willard sits in the boat looking at pictures of Colonel Kurtz the shadow of a metal bar slowly goes from left to right across the pictures indicating that the boat is turning. In the next shot of Clean dancing to Satisfaction we can tell by looking at the sky that the boat is not turning but going straight ahead. (01:15:15)????
Continuity mistake: A soldier walks up to Colonel Kilgore, as he offers the wounded VC soldier water, and says, "I think one of those soldiers is Lance Johnson the surfer". His floppy hat has the name Latigo printed in the dark letters on the back of it. The next time we see the back of his hat when everyone talks with Lance the name Latigo isn't there even though he doesn't touch it. (00:29:45)????
Continuity mistake: A vehicle on the Vin Din Dop bridge is shot by a rocket from Kilgore's helicopter and Lance says' "nice shot Bill" after he sees the car blow up. Colonel Kilgore's helicopter has surfboards on its sides not rocket launchers as was seen when they took off in the last scene. (00:41:45)????
Continuity mistake: Chief Phillips says, "Lance take a 16 on the bow" and we see him walk to the front of the boat past the spot we're Captain Willard was hiding for cover during the attack that killed Clean. The molding was blown off by machine gun fire during the attack but now it's good as new. (01:55:30)????
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: When the Captain asks the Chief for the binoculars the boat is standing still but in the next shot as the Captain is watching Kilgore's men they're moving rapidly towards the shore. However, in the next shot, a close-up of the Captain, the ship is back in the same place and standing still. (00:24:40)????
Continuity mistake: When Dennis Hopper says, "The heads, you're looking at the heads, sometimes he goes too far, he's the first one to admit it" look at the two cameras around his neck. At first the lenses are both pointing outward then in the next shot he turns around and the left camera lens is pointing at the ground. (02:33:40)????
Continuity mistake: Look closely at the shadows going across Chief Phillip's face just before he tries to kill Captain Willard. First they're going from left to right, then in the next shot when he grabs the captain's head, they're going from right to left. This happens several other times in the scene. (02:23:05)????
