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: 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)????
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)????
