Continuity mistake: As they pull up next to the Vietnamese sampan Clean runs to the port side of the boat in order to catch the tow rope. Chef is standing behind Captain Willard in middle of the boat and doesn't move and all. In the next shot Clean and Chef are both standing on the edge of the port side of the boat. (01:34:50)????
Continuity mistake: As Chef grabs the black wig it's clear to see that the window on the helicopter door has a strain crack going down the middle of it. It's there for two shots then when Clean hammers on the helicopter door the first time it's not broken. After he climbs up onto the helicopter and bangs on the front windshield he comes back to the side window a second time and it's cracked again. (01:29:55)????
Continuity mistake: Captain Willard and Lance run away from Lieutenant Col. Kilgore and the captain says, "get the f&% outta here". As this happens a helicopter is flying towards the colonel and two soldiers are helping an injured soldier. The camera cuts away for three seconds then back to a wide shot of the colonel again and the helicopter and the injured soldier have disappeared. (00:51:00)????
Continuity mistake: When the captain realizes that Chef's head is in his lap he moves around violently trying to get it away from him. We can see that both his legs are tied up with wire but in the next close-up of Chef's head on the ground the captain's foot is freely moving around. (02:47:20)????
Continuity mistake: Captain Willard picks up one of the death cards that Lt. Col. Kilgore threw on a dead body and it's the seven of hearts. This is not one of the cards that Kilgore threw down though. As he was naming each one as he threw it and Captain Willard was walking close behind him. (00:28:05)????
