Continuity mistake: When Marty arrives in 1955, he lands on Peabody's farm and rams through the pine tree he then hits a scarecrow which flies over the top of his car. Then as they show it from the inside the scarecrow slams into the windshield - but how can it slam into his windshield if it is already over the car? (00:31:30)
Continuity mistake: When Arnold lets go of the landing gear he lands in the water. A few seconds later we see him walking up towards the beach, and we can now see that he is only wet from his waist down. It's not likely that he would have been able to land standing on his feet and not not becoming completely soaked. (00:24:41)
Factual error: The word 'magician' is spelled 'magicinan' on the cart when Nicholas bends down to collect the spiders web. (00:50:30)
Continuity mistake: When P.W. is escaping certain trouble somehow his handle bar comes off (with ribbons) a new one is replaced (without ribbons) - cool bike huh? But in the next scene the new handle has ribbons... (01:13:00)
Plot hole: When Bond and Tibbett break into the underground lab and find the device which drugs the racehorses, you can see that it has a large light emitting diode (LED) on the top of it. What possible use would that be, since the device is implanted in the horse's leg, and is supposed to be covert? (00:37:20)
Revealing mistake: During the scene when Audrey is having a nightmare about eating too much while on vacation, the nightmare ends with her inflating like a balloon from all the food. Her blouse splits open and down the middle, where the buttons have broken, the dark balloon used for the effect is visible. (00:16:35)
Continuity mistake: When Vernon is in the basement files and Carl walks in, the card in the drawer is tilted and it stays this way for a few shots. In the next shot, the card is straight, but in the shot after that, it is tilted again.
Continuity mistake: When Jerry has Charley pinned to the cracked bedroom wall by his neck, he suddenly drags him over to the window a few feet away - which is nailed securely to the frame - and lifts it up effortlessly. Next, we see Charley looking over to his right side, but now he's back up against the cracked wall in this shot, not a window. (00:29:50)
Continuity mistake: When the paperboy comes around to collect his $2.00 plus tip, Lane keeps the door only open a crack. But when it switches to shots of the paperboy not only is the door wide open but the color has changed from blue to white. (00:22:00)
Continuity mistake: In the POW camp, Co Bao is discovered by a guard who points a handgun at her. Rambo shoots an arrow into the guard's forehead, who then falls back against a tree with his cap down low over his eyes. In the next shot his cap is much higher on his head, and the arrow is pointing at a different angle. How could his cap have moved up that far with the arrow holding it to his forehead? For that matter, how could the arrow have moved when it was firmly embedded in the guard's skull? (00:33:25)
Continuity mistake: During the scene where Fletch is at the hospital trying to locate Stanwyk's medical records, he drops lots of files on the floor and asks a nurse to sort them out. When he is talking to her he has a stethoscope in his ears, but when the camera moves behind him they are suddenly round his neck. Moments later they are back in his ears. (00:18:10)
Continuity mistake: When the lads run over the fire hydrant in Jonathan's father's Studie, the bumper appears undamaged. However, when they pull up in front of his house, the right side of the bumper is badly crumpled.
Revealing mistake: You see Scott walking towards the shower and he says hi to Chubby while passing him, but if you look closely after that you can tell Scott's only wearing a mask and his shoulder is bare skin. (01:00:15)
