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)????
Visible crew/equipment: As he looks out to the surfers Lt. Col. Kilgore says, "It's gonna blow this place out, it's gonna ruin it it's the napalm that's what's doing it" and a mortar shell soon explodes in the water. If you look closely behind the surfer on the left you can see the explosive device floating in the water before the explosion. (00:50:15)????
Continuity mistake: There are four shots of the fighters that drop the napalm. The first time we see the jets there's only three of them and the part of the nose in front of the cockpit is painted black. The second time we see them there are five planes, the third time we see them there are four without black paint and the last time we see them there are three. (00:47:55 - 00:48:45)????
Audio problem: In the first aerial shot of the schoolyard the closed captioning reads, "this should make everything burn" but if you listen closely what the pilot is actually saying is, "can somebody cover that downed bird". Also the helicopter he's talking about hasn't been shot down yet. (00:40:20)????
Continuity mistake: As the chopper pilot circles the courtyard he says, "We've got wounded down there" and a yellow flair is in the center of the courtyard. In the next shot of the soldiers running around down below we see the center of the courtyard but the yellow flare is not there having been replaced by a Vietnamese hat. (00:43:10)????
Continuity mistake: When the helicopters first attack Vin Din Dop we see eight in formation attacking from the beach with the bridge on the left. One second later we're in a helicopter attacking from the other side of the bridge and we can see the entire beach. From this angle we should be able to see all eight helicopters, but we don't and we also don't see any smoke on the beach from the explosions in the previous shot. (00:39:55)????
Continuity mistake: Martin Sheen's fingers are shown many times in close-ups of him reading files such as after the "Satisfaction" surfing scene. They all look the same except for when he picks up Kilgore's death card. The thumbs on this person's hands are much longer than we see throughout the movie and are not Martin Sheen's. (00:28:10 - 01:13:55)????
Continuity mistake: When we first see Captain Willard in the movie he's looking at the ceiling fan spinning above his head. There's only one fan above his head yet we see two different fans in the scene. The first ceiling fan has a different motor and the acoustic tiles show signs of water damage not seen on the second fan. (00:01:50)????
