Revealing: When Daniel is being taught by Terry Silver in the Kobra Kai Dojo, just after Daniel hurts his foot on the training instrument, Terry decides to show him how to do it. The left plank of the instrument, just before it breaks, you can see it's been pre-cut to break easily. (Zoom in necessary.)

Continuity: Towards the end, when Miyagi comes to save Daniel (yet again) he is fighting John Creese. At one point you see the pocket protector fall out of Miyagi's shirt pocket. He never bends over to pick it up, but 2 seconds later, it is back in his shirt pocket.

Continuity: When Daniel goes to get some pots from the store, the girl who is making a pot is wearing a ring on her right finger, yet in all other shots of her right hand the ring has gone.

Continuity: Immediately before the rest period before the beginning of sudden death overtime, the announcer says there are ten seconds left in the period. However Mike begins kicking Daniel and only two seconds later the buzzer sounds for the end of the period.

Continuity: When Daniel is punching the picture of Barnes, he splatters blood all over the place. In the next shot, there are only a few drops on the picture.

Continuity: When Daniel asks Miyagi to teach him how to sweep, he brings out a broom instead. When Daniel is in his car, Miyagi has the broom in his left hand and is lowering it, but in the next shot the broom is in front of him and he is holding it with both hands.

Continuity: When Mike Barnes walks into Mr Miyagi's back garden where Daniel is training, they fight and Terry Silver appears. When Terry puts his book to Mike's face, in the first shot it's on the right side of Mike's face, but next shot on his left, then back on his left.

Factual error: The storyline in Karate Kid 3, based on the happenings and reference points of the first two movies, is supposed to take place roughly about late 1984, or early 1985. However, if you look close at the beginning of the film when Terry Silver drops off John Kreese at the airport, there are several cars that are definitely later 80's models.

Continuity: At the beginning, when John Creese and Terry Silver pull up in front of the bus, there is a red car at the side of the bus, but when John and Terry pull closer to the curb the red car has vanished.

Continuity: When Daniel is being beaten up by Mike Barnes in the Bonsai store, just after Daniel breaks the glass in the window, look to the left of the screen. There are 4 crates, 1 on top of each other, then when Mike throws Daniel away after punching him, look in the background there are 3 crates and then two next to the 3 crates piled up instead of 4, like we saw in the previous shot.
