Continuity mistake: In the rear close-up shot of the Vietnamese machine gun nest the soldier in the dark green shirt is to the right of the soldier in the tan shirt who is firing it. In the next shot the soldier in the dark green shirt is behind and to the left of the soldier in the tan shirt. (00:40:45)????
Continuity mistake: Colonel Kilgore walks over to a VC soldier with a stomach wound and one of his soldiers follows behind carrying a thermos with an orange cap in his right hand and nothing in his left. Kilgore turns and says to this soldier, "Give me that canteen" and in the next shot the canteen appears in his left hand. (00:29:20)????
Continuity mistake: Captain Willard enters the temple after he kills a guard and there's a great shot of him holding the machete as it glistens in the light. He just slit someone's throat not two seconds before and there's not an ounce of blood on the blade and it's not even the same machete he was holding three shots ago when we see his silhouette in the festival lights. The first machete we see has a thinner blade with a hook on the end of it and a different handle. (03:07:05)????
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: When the soldiers come to the door with Captain Willard's new orders a green piece of paper (money) appears behind his gun lying on the table under the lamp. It's there in the close-up but not when they first walk in. The other pieces of paper in front and to the left of the gun are also moved. (00:08:20)????
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: 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: As Colonel Kurtz sits and reads articles to Captain Willard from Time magazine look very closely at the clasp of his dog tag necklace on the left of his neck. Throughout the shots he keeps both hands on the articles that he's reading yet the clasp on his necklace moves down his neck more than an inch without being touched. (02:50:55)????
Continuity mistake: Hubert de Marais says to Captain Willard, "And this is something that you never understood, you American". The gentleman in the tan jacket to his left lowers his cigar towards the ashtray. In the next shot his hand is resting on the table with the cigar between his fingers then he puts it in the ashtray. (02:06:50)????
Continuity mistake: As Lance is on the top of the PBR Captain Willard says to himself, "He's close, he was real close" and they shuttle between shots of Lance and close-ups of Chief Phillips at the helm. The straw hanging down from the roof of the boat behind Chief Phillip's head is is hanging down differently in both of these shots. (02:21:05)????
