Revealing: When Daniel is about to paint the fence of Mr. Miyagi, Mr. Miyagi tries to catch a fly with chopsticks. Daniel tries as well. You can see pretty clearly that the "fly" is attached to a wire or a nylon string, moving like a pendulum and bounces as if someone's pulling the string.

Other: In the semi-final where John Lawrence fights against Darryl Vidal, the female referee has major problems of what to do. When Lawrence gets his first point, the referee first raises her red flag (Vidal is wearing the red ribbon) but then swiftly changes her mind. And when Lawrence gets his third point, the female referee again incorrectly raises her red flag.

Revealing: When Daniel is running from Johnny and his gang after the bathroom incident at the dance, there's a lot of fog outside. If you look at one of the trees in the background, you can see that all the fog is being puffed out from behind the tree - obviously a fog machine.

Continuity: We first see from the inside of the door (and therefore backwards) the instructions that Mr. Miyagi leaves for Daniel to paint the house. In the next shot we see the same note from the outside - from Daniel's viewpoint. Clearly they are two different notes. The left & right arrows switch directions, the drawings of the hands change, the position of Miyagi's signature changes, and the placement of some of the exclamation points changes.

Continuity: In the final fight between Daniel and Johnny, there is a time when Johnny's head band falls off (after Johnny scores his second point). Right after it falls off, if you look quickly you can see it back on, then it goes back off.

Continuity: When Daniel and his mum are in their apartment unpacking, there mum has nothing in her hands in one shot, and in the following shot she has a small red case.

Continuity: When Daniel comes back from the restaurant having just seen Ali with Johnny, Daniel sits down next to Miyagi. When Daniel says, "Banzai," he does not have his arm resting on the small table, yet in the next closeup his arm is now on the table.

Continuity: When Mr. Miyagi rescued Daniel, he didn't hit Johnny in the face at all. The next day, however, Johnny had a black eye.

Continuity: After Daniel's little party at Miyagi's, they both go outside and Daniel sits in the yellow car and Miyagi walks up. In the shot from the front Miyagi has his hands crossed leaning on the car door, yet from the back he has his elbow leaning on the door, then back to just his hands on the door.

Visible crew/equipment: In the scene when Miyagi and Daniel are about to get into Miyagi's truck and drive to the Cobra Kai Dojo, Daniel is yawning and to the bottom right of him the boom mike can be seen for a few seconds.

Continuity: When Daniel gets the spaghetti and sauce spilled all over him, his white pants are drenched with sauce all the way down to his crotch area. When he gets to Mr. Miyagi's house, he only has one faded streak of sauce on each leg and the rest of his pants are clean.

Deliberate "mistake": During the final match, Johnny scores his second point with a forearm to Daniel's side. However it is incorrectly announced as a kick to the side. Johnny was on one knee at the time and in no position to kick him. Also, you can see Johnny throw a forearm and not a kick.

Continuity: When Mr Miyagi saves Daniel from Johnny, you can see that its not Mr Miyagi jumping over the chain fence, but a stunt double.

Continuity: When Johnny and his gang jump Daniel at the chain fence, Johnny smashes the sign on the fence, yet in the following shot the sign is there again, then the shot after its broke again.

Continuity: When Daniel is about to hose Johnny down in the bathroom during the Halloween party, Johnny only has one glove on. When Johnny chases Daniel (and eventually beats him up), he has two gloves on. With all the commotion, he would not have taken the time to put another glove on.

Continuity: In the scene where Mr. Miyagi teaches Daniel defensive moves, Daniel blocks Mr. Miyagi's punches with his right hand on the 'paint the fence' move. Daniel then leaves his right hand high, in a defensive position. This shot is taken behind Daniel, over his left shoulder. The next shot, a side view with Daniel on the right of the screen, shows Daniel's left hand held higher, as if he'd used that hand all along.

Visible crew/equipment: The first time Daniel goes into the Kobra Kai Dojo, when the camera is behind him, you can see a cameraman dressed in black in the mirrors at the other end of the room.

Continuity: When Daniel catches the fly with the chopsticks, he catches the fly in the middle of the sticks. When the shot changes, he now has the fly with the tips of the sticks.

Continuity: Before the dance in Mr. Miagie's work area you can see the red shower curtain with the polka-dots that Danny wears to the dance hanging on the wall. After the dance, when Danny is in the work area after getting saved from the Skeletons, you can still see the shower curtain on the back wall.

Continuity: As Daniel gets out of his mom's car for his first date with Ali, his shoes are white. When we see him being introduced to Ali's parents, his shoes have changed to brown.
